Microsoft Excel: How to Create a Pivot Table
By Reen Rose
Do you work with data in Excel? Are you using Pivot Tables? If you aren't, it may be because you don't know how. You may even be a little in awe of them and think your Excel skills aren't up to tackling these mysterious creations. Nothing could be further from the truth. I can't think of anything that is surrounded with as much undeserved mystique as Pivot Tables. Let me show you how to create one from raw data. In fact, describing the steps is much more challenging than it is to insert one into your workbook.
The concept of Pivot Tables has changed very little since they were originally introduced, but with every new version of Excel, Microsoft has introduced changes to the method of creating them. I am basing my article on Office 2010 so things may look a little different on your screen. Start by finding some data that you would like to summarize. It needs to be set up correctly in a table or database.
1. Click on any cell in your data.
2. On the Insert ribbon, in the Tables group, click on the top half of the Pivot Table button.
3. A dialog box will appear. Your data should have a flashing line around it, to indicate the cells that Excel thinks you want to summarize. You can alter this if needed. Leave New Sheet chosen for the last option and click OK.
Your screen should have a Field List pane on the right side and a box that says Pivot Table # and some text and graphics on the left. This is the point where many first time creators get a terrified look in their eyes, close the workbook without saving changes and deny they were ever there.
One way to get a basic understanding of the parts of a Pivot Table is to imagine an attendance record like the ones used in school. Generally, the dates are put in the first row (the Column Labels) and the names of the students down the rows in the first column (the Row Labels). A mark is made in the intersecting cells (Values) to show whether the student attended or not. This example doesn't accurately represent the way you collect data in Excel, but it serves our purpose of identifying the areas within a Pivot Table.
Now that we know the areas, we can return to creating one:
4. On the right of your screen you should see the Field List. The field headers from your data should be in the box at the top. Any header that you drag into the Column Labels box will go across the top of your table. Any header that you drag into the Row Labels box will go down the left side of the table. Any header that you drag into the Values box will be summarized in the cells in the center. If the header you drag represents numbers, you will have totals, but if the header represents a field of text the count function will be used for the value.
5. If you want to remove headers from any of the boxes, just drag and drop them anywhere in the Choose Fields box.
6. You can add more than one field to the Row or Column labels. Try dragging these headers to change their order and you will get a very different look. To create a linear table, only put headers in the Row Labels, leave the Column labels box empty.
The best way to begin your journey with Pivot Tables is to drag field headings in and out of the different areas and see what happens. The type of table you want to create depends on the type of information you want to find. It can be a process of trial and error. This article only scratches the surface of what you can do with Pivot Tables, but first steps are important and I encourage you to get acquainted with this powerful Excel tool. You never know what you may be able to accomplish.
Helpful Tips
1. As long as your Pivot Table is active you will see contextual ribbons (Pivot Table Tools) with two tabs (Options, Design). This is where all the Pivot Table tools are. If you are not clicked onto the Pivot Table, or the Pivot Table box that is on the left of your screen when you first insert a Pivot Table, these tools will disappear.
2. A valid database may have empty cells but there shouldn't be any completely empty rows or columns.
3. If you accidentally close the Pivot Table Field List that is on the right of your screen, click on the Field List button in the Show group of the Options tab of the Pivot Table Tools to get it to reappear.
4. Your data is on another sheet of your workbook. Look at the tabs at the bottom to find it.
5. You can make more than one Pivot Table for the same data.
6. If you make any changes to the data and you want it to be reflected in your Pivot Table, you have to update/refresh the table manually. This gives you the option to leave the table unaltered while more raw data is being added.
a. Choose Refresh from the Right-click menu (right-click on the Pivot Table).
b. Click on Refresh from the Data group on the Options ribbon of the Pivot Table Tools.

Microprocessors - The Most Essential Device for Endless Applications
By Joe Faruqui
About Microprocessors:
By definition, a microprocessor is a multipurpose, programmable device that takes digital data as comments, processes according to a set of instructions stored in memory, and returns results as output. Every action or command you input into a computer goes through this same basic process to get the results, a process which is most likely an afterthought for most of us. Microprocessors use sequential digital logic and operates on numbers and symbols with the binary numeral system, which is a base-2 numeral system using only 0 and 1. Microprocessors merge all the functions of a central processing unit (CPU) on one or at most a few integrated circuits.
Significance of Microprocessors:
Microprocessors are undeniably the most essential device in the world as we know it today. You are using a microprocessor at this very moment to read this article. Nowadays, all modern computers are microprocessors by definition, thereby making the prefix micro redundant. The way that processors have transformed society is due largely in part to the introduction of low-cost computers on integrated circuits. Personal computers are general purpose microprocessors that are used for text editing, multimedia display, computation, and communication on the Internet, something we are all familiar with. In addition, embedded systems use microprocessors, which give control over a huge variety of devices, from appliances and mobile phones to cars and the entire industrial process.
History and Quick Advancements till Date:
The very first microprocessor, the 4-bit microprocessor 4004, was introduced by Intel back in 1971, followed shortly there after by the 8-bit microprocessor 8008 in 1972. The very first processors used small to medium-scale ICs that each contained anywhere between ten to a few hundred transistors. As technology advanced, the entire CPU can be integrated on a single IC, which greatly reduced the cost of processors. Single-chip processors also increase reliability and decrease the risk of failing electrical connections. Now that microprocessors are integrated on very small ICs, many older forms of computers are completely obsolete. In fact, only a handful of microprocessors are used in everything from handheld devices to the largest supercomputers. At the rate of present technology, the capacity of microprocessors doubles every two years.
Most Popular Processor Families:
These are some of the most popular processor families, most of which you probably recognize, as they are used in your own computer:
A majority of these are Intel products, and understandably so, as it is arguable that Intel is one of the largest producers and designers of microprocessors today.
You can browse on the web for leading distributors of all types of Computer Microprocessor Parts from a comprehensive list of manufacturers. On these sites, you can get tier 1 pricing from manufacturers which pass selected savings to you.

Ways to Increase Battery Life of Your Laptop
Even with all the modern technology that is available in the world today, there still is not a laptop battery that can last all day long without it being recharged. This can be rather irritating especially if you can not find a plug to plug your laptop into. This always happens when you need your laptop the most, Murphy's Law you know.
Here are some tips on how to preserve the life of your laptop battery during the day or evening so you can avoid having to scramble for an outlet.
1. Screen Backlighting
Lowering the brightness of your screen will save you a lot of battery life as the brightness takes up a lot of battery juice. Set your backlighting so that it automatically lowers when you unplug your laptop.
2. Stop scheduled tasks
Your virus scanner and automatic updates run on a regular schedule. Disconnect these from automatic so you have to turn them on manually. This will save on your battery life. Run these only when your laptop is plugged into an outlet.
3. Unplug USB devices and discs.
When you have something plugged into your USB drive your laptop's battery is constantly connected to that device. The same with CD's which are sitting idle in your laptop; even though they are not being used, your laptop is reading them. Remove what you don't need to use when using your laptop if it is not plugged in.
4. Turn off all messaging apps.
By turning off your messaging apps and Skype you will be able to save a lot of battery life as these apps are constantly pinging the web. If you are watching a movie or working on a project you don't want to be bothered anyway so turn these off and watch how much juice your battery will keep.
5. Turn off your volume
If you are not in need of using your volume control while you are working on your laptop simply turn it off or mute it. Believe it or not even if you put your volume control all of the way to the lowest mark it is still using your battery. Simply shut it off or mute it when you are not using it.
6. Clean your battery contact
By using rubbing alcohol and water wipe down the contacts on your laptop battery. Making sure your battery contacts stay clean will help preserve the live of your battery. Make sure they are completely dried before returning the battery to your laptop.

Can the Government Really View Your Emails?
Internet and email users expect their information and interaction with others is inherently private. That is not the case. The FBI routinely conducts scans and screens on a regular basis. The Freedom of Information Act has opened the door to a new dawn of internet scrutiny. What does that mean for the average person who is using email to correspond with family, friends and business contacts?
Some basic security precautions are to think before acting. Never open attachments from unknown or unauthorized sources. Hackers use these to infect computers with viruses, to steal information and even bank accounts.
Anyone who uses their employer's internet service to send personal emails can expect that information to be read on a regular basis. Most companies now require new associates or employees to sign a waiver allowing the employer to do so. Since many new hires sign anything placed before them, you may have done this and never even knew it.
All email and internet contact leaves an indelible record. Just clicking the Delete button does not erase the message. People trained and skilled in retrieval can recover this information and bring it back to haunt the person who wrote it.
These can be used in court, in custody disputes and divorce cases.
What does that mean for the right of speech and reasonable privacy? The public has a right to privacy as long as that right is not used outside the bounds of the law. If the police, FBI or any other law enforcement agency feels the need to inspect a person's email and internet usage, all rights are immediately forfeited. There are ways to ensure security and privacy for someone who is honest and ethical, one who just desires a bit of privacy.
Email and internet security can be found through Remailers. These are networks that receive coded messages with instructions on where to send them without revealing where they originated. More and more email servers are emerging that do not require the user to provide their actual name, telephone number or other information. These can be had for a monthly or yearly fee.
While once the domain of radicals or people who have something to hide, these remailers and email servers are becoming more popular as privacy concerns arise. A sharp increase in identity theft, banking hacks and other issues that create a sense of violation, make these a haven for honest people.
Cookies are collected by almost every place a user visits. These can be seen by anyone monitoring that website and allow an innocent user to be located if the government, FBI or any other agency chooses to do so.
Email privacy and security essentials are serious matters, one that is individual to every person. Some people just don't care if their communications are read because they have nothing to hide; others have nothing to hide but demand privacy because it should be expected. Whatever one's decision, research shows this is an issue that will only become more prevalent as internet use continues to increase.

iPhone 6 Review
by Emilia Brantingham
The new apple iphone might be among the most critical tools in the Cupertino brand name's history - with the iPhone 5S and apple iphone 5C simple updates to previous models, there's a great deal of tension loaded on the apple iphone 6.
As each typical, the web is flooded with rumor, conjecture and downright lies over this next-generation mobile, which is why we invest our time trawling with each nugget of info, debating its benefits and curating it into this easy-to-read hub for all points iPhone 6.
iOS 7: Apple's face-lift for apple iphone and iPad
A portion of you could have been anticipating the iPhone 6 to have actually debuted in 2013, yet offered the apple iphone's past - from the 3G onwards, there's consistently been a half-step S version before the next phoned number iPhone - we were never getting the 6 up until 2014. Actually, it will technically be the iPhone 8 by that point... however hi, that's counting these days?
Something is for sure, with the Samsung Galaxy S5, HTC One 2 and Sony Xperia Z2 just around the bend, Apple will certainly have to be on its video game with the new mobile - and numerous think a bigger monitor is simply a must.
apple iphone 6 release day
The iPhone 6 launch day will be in 2014, although exactly when that will certainly be in the year is still a little confusing.
Below's just what we assume is likely to take place: at WWDC in June this year we'll see the obvious release of iOS 8, however additionally a larger-screened iPhablet as Apple plannings to create itself ahead in Eastern markets and rivalling the likes of the Galaxy Note 3.
We 'd have usually offered this type of report a broad berth, yet multiple reports have actually mentioned a larger device from Apple at the June event, so we're starting to provide them some credence. At the very least, Apple is certainly examining it, yet could not create it to market.
Afterwards, Apple will launch the iPhone 6 in September, in addition to the iWatch and the initial view of iOS 8, to permit it to both create a brand-new product to market in addition to keeping its schedule secure. This is backed up by KDB Daewoo Securities, which does have a suitable document in Apple early leakages.
Apple has actually launched the continue couple of iPhones at an unique occasion in September, so the wise cash is on September 2014 for the iPhone 6's landing but won't be the only mobile hardware we view from the firm this year.
After trawling through all the iPhone 6 reports we kicked our render machine into equipment and came up with an idea of just what we 'd such as Apple's 8th generation flagship mobile phone to resemble.
Baseding on Business Expert, of the many apple iphone 6 prototypes Apple has actually made, one has a huge Retina+ IGZO display and a "brand-new kind aspect with no house button. Action control is additionally perhaps consisted of." It will certainly feature Apple's new Touch ID finger print tech though?
The Retina+ Sharp IGZO show would have a 1080p Full HD resolution. It's additionally been extensively mentioned that Apple can present 2 handset sizes as it looks for to take on the variety of Android tools now on the market - with both being a great deal thinner thanks to huge enhancements in LED backlight innovation to lessen the density.
We reckon there will certainly be two screen dimensions and resolutions, as mentioned over. A Full HD display makes best feeling for the apple iphone 6, especially if it expands to a 4.7-inch screen as mooted, and the iPhablet will push things even additionally to maintain the Retina encounter on a bigger display.
In fact the 4.7-inch iPhone 6 has been tipped again along with a bigger 5.7-inch model as part of Apple's double assault on the marketplace adhering to the FIVE and 5C.
The exact same source asserts the apple iphone 6 (in both its sizes) will take layout hints from the iPhone 5C and the seventh-gen iPad Nano which introduced in 2012.
In other areas, patents show that Apple has actually been thinking about magical changing technology that can hide sensing units or even video cameras. Will it make it into the iPhone 6? Possibly not.
That stated, there's still a little possibility of the apple iphone 6 sporting a versatile wraparound show after more patents were discovered, however we think that's most likely to include on the iPhone 7 or 8 rather.
Back in September last year, rumors indicated a 6-inch display, with additional talk of a phablet sized 6-inch iPhone claiming it could arrive as early as May 2014 - which jives beautifully with the above chat on an iPhablet.

Advantages and Disadvantages of a BIOS-Embedded Windows 8 Product Key
By Yasir M Chohan
Windows 8 has become a very popular Operating System among Windows users. However, Microsoft has made things a little different for its users. Previously, the product key on a computer that had a pre-installed Operating System was printed on a sticker. For laptops, the sticker was placed on the bottom of the laptop near the battery compartment. On desktops, this sticker could be found on the side of the computer. However, Microsoft has decided to do things a bit differently by embedding the product key of the new Windows 8 Operating System in the BIOS of the computer. This move will affect the user in a number of ways as there are various advantages and disadvantages.
Advantages of the BIOS embedded product key
The first advantage that the user will get from this is that they do not need to look for the product key each time they need to reinstall Windows. In the past, when reinstalling the OS, the user had to look for the original key and input it before proceeding with the installation. This could sometimes be difficult for some users. The Certificate of Authentication sticker could wear out, and the digits would become difficult to read. In fact, the digits were sometimes too small to read. However, since the key is now embedded in the BIOS, the OS will recognize it immediately and proceed with installation without requesting for this activation information.
Users can now be sure that they are getting genuine Windows products. In the past, people would sell pirated OS and use a generic product key. However, after a while, the user would get a notification that their product is not genuine. This means that they would not get support or updates from Microsoft. However, if it is set in the BIOS, they will not need to get a generic product key from an untrustworthy source.
Microsoft itself will benefit a lot from this. In the past, people used to share product keys. This increased the opportunities of copyright infringement and piracy. However, if the activation details are embedded in the BIOS, they cannot be used by another computer. This will reduce the instances of piracy and sharing of activation details.
Disadvantages of setting product keys in the BIOS
The fact that the activation details cannot be used on any other computer could be disadvantageous for some users. For example, in case the PC or laptop dies or the motherboard stops functioning, the Operating System dies with it. This means that they cannot attempt to reinstall the system after they replace the motherboard. This is because the activation details were locked in the original BIOS.
Also, each key is tied to a PC. Therefore, if a PC dies, and the owner is forced to buy a new one, they will have to buy another OS as well. They will not be able to use the installation disc that they already have on this new computer.
This new route that Microsoft has taken has both advantages and disadvantages. However, unless one damages their computer or motherboard, they will be able to enjoy the use of the OS without any problems.
Individuals can now get genuine Windows 8 product key for use on their computers without experiencing any problems.

Samsung's Latest Smart App!
By Philip M Tomich
Companies are always trying to outdo each other when it comes to app development and continual improvement. Samsung, however, has created a new Gear Smartwatch that is going to change the way applications are accessed. Even more creative - this application will not run on Apple's iOS, either.

Samsung has been able to reinvent the app market by placing a smart application on a new, yet familiar platform. The question will now become our people going to really use a watch versus are smart phones? Google believes they will, which is why the native company is doing everything possible to offset Gear.
When you are planning to develop an app of your own, you might want to consider how Samsung decided to bypass Google by beating the company at its own game. They beat them at their own game by not doing what they do with different branding, but by doing what they do in a way that is better and different!
Take notice of these changes to the app industry when developing your next app. Think long term technology versus consumer embraced trends. Will you be able to cater to both? If not, why?

Also, updating to the latest version gives access to the latest and most new features. So, follow the method that is mentioned below to make this possible. The method is divided into two categories. First is for updating Chrome on Mac, while the second one is for updating Chrome on Windows.
For Updating Google Chrome on Mac
· Begin by opening the Chrome web browser. In case an update is available, a small green arrow will be displayed on the top of the Chrome menu in the browser toolbar. The Chrome menu is pictured as a box made from parallel lines that sits on the right side of the search bar on the upper part of the page. In case the arrow is not visible, it means you already have the latest version updated. But, in case the green arrow is seen, move to the next step.
· Next you must click on the Chrome menu
· Now, you must click on Update Google Chrome, which is present as a second last option in the drop-down menu. After clicking, a confirmation will be asked where you again need to click, yes.
· Finish by clicking restart, in case you do not wish to restart, choose Not Now. So, the next time you open your Chrome browser, it will be already updated in the latest version.
For Updating Google Chrome on Windows
· Begin by opening the Google Chrome web browser
· Now, on the top right hand corner, click on the wrench icon, which is also referred as the Spanner icon
· Next click on "About Google Chrome", which will redirect you to the dialog box. If you have an older version of the browser installed, you will see messages reading Installing New Browser. In case, this message is not seen, it means your PC already has the most recent version of Chrome installed. In case you see the message, read the next step.
· You now need to wait until the browser gets updated, when done, you will again see the Chrome dialog box, which will ask you to "Re-launch Google Chrome". Clicking so, will give you the latest version of Chrome.
So, here is a simple method of keeping your web browsing experience secured, by easily updating to the latest version of Chrome. In case you need any other kind of help, support is available with the Chrome tech support experts.

The 10 Android Tablet Apps You Shouldn’t Live Without
by Jack Holt 
10. – DashClock Widget - (Play Store Link) This app is amazing. The kicker is that it only works with Android 4.2 and up. What makes this app so amazing is that I can look at my notifications straight from my lock screen. I can check Google Voice, Falcon Pro, as well as Gmail without unlocking my tablet. What’s even better is that more extensions are being added all the time. If you’re using the Nexus 10 or have a 4.2 ROM installed, than you need to download this app.
09. LilyPad HD - (Play Store Link) LilyPad is a great little social app because it floats over your home screen, which allows you to chat with your friends while using your tablet to do other things. Unlike the beta version this app supports multiple clients. MSN, Facebook, AIM, Yahoo, they’re all there. The free version only supports Google Talk, but a one time purchase of $2.99 makes the rest of them available as well as gets rid of ads. This is a must have if you’re always chatting with friends and family. If you’re worried that it’ll get in the way, you shouldn’t. because it minimizes to almost nothing and is easily accessible through the Notification Bar.
08. Nova Launcher - (Play Store Link) This is probably one of the first apps that I install with each tablet. It takes the stock Android launcher and adds many bells and whistles. It allows for bigger folders, multiple scroll effects, widgets in the dock, and so on. While there are others out there, Nova has proved itself with great performance and customization. The Prime version has more transitions as well as unread counts and swipe gestures. While many would be happy with the standard interface that their tablet gives, this one is my go to for a more stock experience with the added benefits of customization.
07. Google Voice - (Play Store Link) I love this app because not only does it sync my voicemail, but it allows me to send and receive messages from my tablet. It’s a great way to send messages to other friend’s devices in an SMS fashion. Plus if you’re like me and flash different ROMS constantly, it’s a good way of keeping those messages backed up and synced across multiple devices. I know some people who use that solely as the way to communicate foregoing their phone’s SMS app altogether.
06. Drive - (Play Store Link) Given that we here at TalkAndroid use Drive for all our writing needs it’s important to have. What makes it great is just like Google Voice, everything is in the cloud and can be seen across multiple devices. I can create and edit documents, work on spreadsheets as well as work on presentations right from my tablet. Hook up a Bluetooth keyboard and I have a perfect laptop replacement for writing. While it does have its limitations, Google is slowly making strides to improve the overall experience. Here’s hoping that their acquisition of Quickoffice makes the mobile office experience even better.
05. Netflix - (Play Store Link) While I also use Hulu Plus, Netflix can’t be beat for the library it has. Most of the shows that I’ve watched over the years are there. The movie selection could be better, but it’s getting there. The quality isn’t bad, and for the most part, shows and movies stream in HD quality. It’s a perfect way to kill some time while traveling or waiting for a class to start.
04. Chrome - (Play Store Link) While not on par with its desktop counterpart, Chrome for Android has come a long way from our initial review. While I touted it for being a well developed piece of software, it has come a long way. Since our review, it has added tons of features as well as sprouted off a beta version. The speed of the app is still a factor, but I can look past the few extra seconds for the ability to sync across devices. It’s handy for if I’m reading or researching something on my desktop or other device, and I have to leave, I can quickly open the same page on any of my other devices.
03. Kii Keyboard - (Play Store Link) With a plethora of keyboards out there to choose from, it’s hard to distinguish yourself from the pack. With apps like Swiftkey and Swype always in the spotlight, sometimes it’s hard to notice others. Kii Keyboard is such a keyboard. Built upon the Android 4.2 keyboard, it has everything you’d expect. It has next word prediction as well as gesture (Swype) typing. It supports themes like Go Keyboard and offers the ability to split the keyboard for easier thumb typing. I can’t think of a keyboard that I would recommend more.
02. TalkAndroid - (Play Store Link) No this isn’t just a plug for you to get our app but it doesn’t hurt. I came across the app before I started writing for TalkAndroid and I was very impressed. The app was created following Android Design Principles and the quality shows. You can easily navigate through each section and find what you’re looking for. Articles are easy to read and posting comments is a breeze. It’s a great way to keep up with us here at TalkAndroid without the need of a web browser.
Honorable Mention - Carbon Back Up (Play Store Link) - A recently developed app by Koush, CyanogenMod and ClockworkMod developer, Carbon Back Up is a great way to backup and sync data across multiple devices. I haven’t used it enough to give it a full review but from what I have used of it, I had to mention it. You can backup Messaging (SMS) data, launcher data, as well as data from any app you use. The great aspect for this is that you can sync the data on any of your devices. I tested it out when I switched from the G Note 10.1 to the Nexus 10. It saved my game progress from Simpsons Tapped Out so I was able to continue where I left off on the Nexus 10. This works for root and non-root users alike, and if you’re curious about using it, we have a handy guide for you to look at.
And that’s it. These are the ten tablet apps that I can’t live without and neither should you. There are many other apps out there that I use. but these are the first ten to get downloaded.
Understanding How Anti-Virus Software Works
A computer virus is a self-replicating program which installs itself on your computer without your consent. It does so by inserting itself into other programs, data files, or the boot sector of your hard drive. Once this happens, the affected areas are said to be 'infected'.
The vast majority of viruses perform some sort of harmful activity on their hosts. A virus may access your confidential information (such as your banking details), corrupt data or steal hard disk space or processing power, log your key-strokes and spam your contacts. If you are extra lucky, however, it might only display humorous, scatological or political messages on your screen.
Anti-virus software is used to detect and remove computer viruses. It consists of two basic types: signature scanners and heuristic detectors. Signature scanning is used to identify known threats, while heuristics are used to find unknown viruses.
Infected files
In the old days... less than a decade ago... most viruses were contained in executable (or program) files, ie files with extensions such as .exe or .com, so anti-virus software only had to check these kinds of files. Nowadays anti-virus software has to check a greater variety of files, including Microsoft Word documents and other non-executable (and seemingly harmless) files.
In MS Word, a macro is a set of instructions you record and associate with a shortcut or name. You can use a macro, for example, to save the text of a legal disclaimer. You can then add the text to any document you are writing (without having to retype the disclaimer) by just pressing the particular shortcut key combination or clicking the macro name.
Despite the time they can save, macros present a risk. Rogue programmers can use them to hide viruses within documents which they send as email attachments to unsuspecting victims. Once they open the attachments, the victim's computer is infected.
Nasty little programs can also be embedded in other non-executable files, so that opening these files can result in infections.
Some email programs, such as MS Outlook Express and Outlook in particular, are vulnerable to viruses embedded in the body of an email. You can infect your computer just by opening or previewing a message.
Identifying viruses
There are several methods which antivirus software can use to identify files containing viruses: signature scanning, heuristic detection, and file emulation.
Signature scanners
Signature-based detection is the most common method of identifying viruses. It involves searching the contents of a computer's boot record, programs, and macros for known patterns of code that match known viruses. Because viruses can embed themselves anywhere in existing files, the files have to be searched in their entirety.
The creators of the anti-virus software maintain the characteristics of known viruses in tables called dictionaries of virus signatures. Because thousands of new viruses are being created every day, the tables of virus signatures have to be updated regularly if the anti-virus software is to be effective when it checks files against these lists.
To avoid detection, rogue programmers can create viruses that encrypt parts of themselves or that modify themselves so that they do not match the virus signatures in the dictionary.
In practice, the signature-based approach has proved very effective against most viruses. However it cannot be used to find unknown viruses, or viruses that have been modified. To counter these threats, heuristics need to be used.
Heuristic detectors
Heuristic-based detection involves trial-and-error guided by past experience. Heuristic detectors will, for example, look for sections of code that are characteristic of viruses, such as being programmed to launch on a particular date.
The use of generic signatures is a type of heuristic approach that can identify variants of known viruses by looking for slight variations of known malicious code in files. This makes it possible to detect known viruses that have been modified.
File emulation
File emulation is another heuristic approach. It involves running a file in a sandbox, an isolated part of a computer in which untrusted programs can be run safely, to see what it does.
The actions the program performs are logged and if any of these are deemed to be malicious, the anti-virus software can carry out appropriate actions to disinfect the computer.
Memory-resident anti-virus software
Memory-resident anti-virus software installs programs in RAM that continue to operate in the background while other applications are running.
A computer's hard disk is where computer programs and files are stored, while RAM (random access memory) is the memory that programs use when they are running. When starting, a program is first loaded into RAM. Once programs have finished running they exit RAM. In addition, RAM is volatile, ie when the power is turned off everything in RAM is wiped out. By contrast, the programs and files on your hard disk remain when your computer is powered off.
Memory-resident anti-virus programs monitor a computer's operations for any action associated with viruses, such as downloading files, running programs directly from an internet site, copying or unzipping files, or attempting to modify program code. It will also be on the look out for programs that try to remain in memory after they've been executed.
When they detect suspicious activity, memory-resident programs halt operations, display a warning message, and wait for the user's OK before allowing operations to resume.
Drawbacks
Despite its undoubted benefits, antivirus software has a few drawbacks. Because it uses computer resources, it may slow your computer down a bit, though this is not usually very significant.
No anti-virus software can provide full protection against all viruses, known and unknown. Once installed, however, it can lull you into a false sense of security. You may also find it difficult to comprehend the prompts and decisions the software throws up on your screen now and then. An incorrect decision may result in an infection.
Most anti-virus software uses heuristic detection. This must be fine-tuned in order to minimise false positives, ie the misidentification of non-malicious files as a viruses.
False positives can cause serious problems. If an antivirus program is configured to immediately delete or quarantine infected files, a false positive on an essential file can render the operating system or some applications unusable. This has happened several times in recent years, even with major anti-virus service providers such as Symantec, Norton AntiVirus, McAfee, AVG and Microsoft.
Anti-virus software can also pose its own threat, because it usually runs at the highly trusted kernel level of the operating system, thus creating a potential avenue of attack. It needs to do this in order to have access to all potential malicious process and files. There have been cases where anti-virus software has itself been infected with a virus.
Finally, it's best to remember that not all heuristic methods can detect new viruses. This is because the rogue programmers, before booting their new viruses into cyberspace, will test them on the major anti-virus applications to make sure that they are not detectable!

It needs to do this in order to have access to all potential malicious process and files. There have been cases where anti-virus software has itself been infected with a virus.
Finally, it's best to remember that not all heuristic methods can detect new viruses. This is because the rogue programmers, before booting their new viruses into cyberspace, will test them on the major anti-virus applications to make sure that they are not detectable!
