What is Antivirus software?

Antivirus software is a program that can detect and eliminate viruses on a computer. A virus removal software application uses two common methods to detect viruses. One method is of using a list of virus signature definitions. In this method the contents of computer's memory (RAM and boot sector), files stored on removable or fixed drives (floppy drives, hard drives) are examined, and then compared with files against the database of known virus signatures. This method gives protection to the computer against only those viruses whose virus signatures are stored in the database.

The second method is based on heuristic algorithm to find out viruses based on common behaviors. This method is more effective as it can detect those novel viruses that antivirus security vendors have yet to create a signature for.

How to Evaluate Anti-Virus Programs

The security software industry is a billion-dollar industry. According to a 2009 article published in The New York Times, the leading security software company, Symantec, made approximately $1.8 billion in 2008 alone. With such a massive market, many software companies are developing antivirus programs. Consequently, choosing an antivirus program can be a confusing task. Fortunately, there are several simple questions that you can ask yourself in order to make the task more manageable.

Instructions

Write the names of several antivirus programs that you are considering across the top of a sheet of paper or spreadsheet. Consult the various manufacturer homepages and free trials of the software in order to gather the following information.


Determine the cost of the programs. Several antivirus programs, such as Windows Defender, AVG Free Anti-virus and BitDefender Free Edition, are free. The advantage of a free antivirus program is obviously the cost. The main disadvantage is a lack of technical support and often reduced functionality. The price of an antivirus program may or may not be important to you. However, you should note the price of each antivirus program so that you can clearly see the differences.


Use free trials or demos of each program to find out which programs are easy to use. The importance of this depends on your level of computer knowledge. Mark on your paper or spreadsheet which antivirus program is easiest to use.


Investigate each antivirus program's technical support. Most antivirus programs will offer some level of technical support. However, the kind of technical support offered is important. For example, does the antivirus program supply a telephone number that you can call or just an e-mail address? If it supplies a telephone number, can you use it 24 hours per day? Mark which antivirus program offers the best technical support.


Check out the antivirus program's detection rate. In order to be effective, an antivirus program needs to detect a large majority of the viruses that it is confronted with. Antivirus programs that have a good detection rate have received the Checkmark Certification. Visit the Westcoast Labs homepage (see Resources) to see whether the antivirus program you are considering has received the Checkmark Certification. Mark on your chart which antivirus program has received this certification.


Try out the program's update features. An antivirus program that is not up to date is useless against new threats. Most antivirus programs can be updated manually. Some antivirus programs update themselves automatically every day. Place a mark under the antivirus program that offers the best update features.


Add up all of the marks to determine which antivirus program received the most check marks. If there is a tie between two antivirus programs, consider reading a review about each program from a reputable technical website, such as CNET or PC World.

Analyze Anti-Virus Best Program

With a wide variety of products to choose from, it can be difficult to decide which anti-virus program is best for you. Consider performance, ease of use and the quality of customer support when analyzing an anti-virus product. Internet surfing habits should also be taken into account. For example, someone whose teenage children use the family computer to access peer-to-peer networks might need a more robust security program.

Instructions

Read the description of features on the anti-virus to determine if the program's features are suited to your individual needs. Features offered can vary considerably. Some programs, for example, may offer email and instant-messaging protection. Others have the ability to detect as yet unidentified viruses based on their behavioral profiles, and to root out sophisticated forms of malware, such as rootkits, which disguise themselves within system files. If you are worried about spyware being installed on your computer, check if the anti-virus software offers additional protection against spyware.

Check out how well the program performs. An anti-virus program's performance is determined by how effective it is at detecting and removing viruses and preventing them from being installed on a clean system. If a program has won a lot of awards, been certified by a security company, such as West Coast Labs, and received favorable reviews, it should effectively protect your computer from viruses and other forms of malware.

Seek expert opinion. Established security websites often test and compare anti-virus software products for performance, features, ease of use and customer support. Such impartial performance tests and reviews are made freely available to help someone to make an informed choice. They also enable people to make quick side-by-side comparisons of security products, to determine which offer the features that best suit their needs, as well as the level of computer resources they may require.

How to Analyze Best Anti-Virus ?

It is vital to properly analyze an anti-virus program before you decide to spend your hard-earned cash on one--after all, it will be a vital line of defense for your system. There are a number of factors you should consider when looking at an anti-virus in order to ensure that you buy a product that can serve all your needs, from battling spyware to a money-back guarantee in case of disappointment.

Instructions

Look at how much the anti-virus will cost. Different products can range from $39.99 (McAfee's cheapest home-security package, September 2010) to over $60 (Kaspersky Pure, September 2010.) There are also free anti-virus programs on the market, but they can be less reliable and offer less customer support.


Consider the level of support the anti-virus software offers. This will be outlined among the features on the back of the box or on the product's website. An ideal anti-virus product will offer live chat support, no-charge telephone support and email support 24 hours a day, 365 days a year.

Make sure the anti-virus software is compatible with your version of Windows. As an example, the latest iteration of Kaspersky anti-virus is not compatible with a Windows operating system as recent as Windows 2000, so make sure your choice is supported by your version of Windows.


Ask whether your chosen anti-virus software will receive regular updates. This is vital to ensuring your anti-virus stays up to date in the fight against new malicious files. Regular updates are essential, as viruses and spyware are always evolving.

Check whether your choice includes anti-spyware capabilities. A good program will fight threats from viruses, Trojans and worms as well as protecting your computer against easier-to-spot viruses.

Key logger is Now an Even Better Choice

Hwsuite’ recently improved LightLogger keylogger (v 2.2.7.0) is now an even more attractive option for anyone seeking a small, versatile, easy-to-use stealth keylogger. LightLogger’s computer monitoring software evades detection by most malware detection programs yet monitors a remarkably wide range of user activities. The language used in LightLogger’s simple, intuitive interface now switches easily between German, Spanish, Italian, and English. In addition, the current version works on Windows XP, Vista, and Windows 7. You can try this lightweight but effective spy software and keylogger before purchasing a license by downloading and registering a trial version from Hwsuite at keylogger.

LightLogger is computer monitoring software that records the activities of users on your computer, allowing you to keep track of your children’s online browsing and messaging, your co-workers’ use of your system, or your family’s internet and email activity. When you run LightLogger in stealth mode, the monitoring is invisible to all but the most technically sophisticated users. You can even configure LightLogger to secretly make screenshots of your computer monitor’s content at intervals you select, and you can customize the resolution of the JPG images to keep file size low.

LightLogger’s core keystroke logger operates in Windows at a level that enables it to monitor keystrokes typed in all applications, capturing passwords in all applications as well as Windows user logon passwords, something that many higher-priced keystroke loggers and monitoring software are unable to do. LightLogger’s keystroke logs now show the context within which text is typed in each application. Text typed in any web-based email application (like Yahoo), PC email client (like Outlook), social networking page (like Facebook), or other messaging application is captured by LightLogger. And you can easily set keystroke logs to display special characters such as Tab, Backspace, and Enter keystrokes. In addition to screenshot and keystroke monitoring, LightLogger also logs websites visited, programs run, and content copied to Windows clipboard. LightLogger logs websites visited and keystrokes typed on web pages opened in most popular web browsers, including Internet Explorer, Firefox, and Opera.

If you activate LightLogger monitoring software with a paid license, you can use it in stealth mode, which makes it an invisible keylogger concealed from all but the most sophisticated computer users. In addition, LightLogger installs and runs as a stealth keylogger undetected by most anti-virus, anti-malware, and anti-keylogger applications, including Kaspersky Anti-Virus and McAfee AntiVirus. Virustotal (http://www.virustotal.com/), for example, recently found that LightLogger was detected by only 2 of 43 widely used malware detection programs. Finally, you can access LightLogger technical support by sending a text message through the application itself (with an internet connection) or by email. As development continues on LightLogger, it remains an excellent spy software selection if you want a simple yet highly versatile and easy-to-use invisible keylogger.
