An antivirus tool is an essential component of most anti-malware suites. It must identify known and previously unseen malicious files with the goal of blocking them before they can cause damage. Though tools differ in the implementation of malware-detection mechanisms, they tend to incorporate the same virus detection techniques. Familiarity with these techniques can help you understand how antivirus software works.

Antivirus software is a type of utility used for scanning and removing viruses from your computer. While many types of antivirus (or “anti-virus“) programs exist, their primary purpose is to protect computers from viruses and remove any viruses that are found.

Most antivirus programs include both automatic and manual scanning capabilities. The automatic scan may check files that are downloaded from the Internet, discs that are inserted into the computer, and files that are created by software installers. The automatic scan may also scan the entire hard drive on a regular basis. The manual scan option allows you to scan individual files or your entire system whenever you feel it is necessary.

Antivirus software identifies, prevents, and removes malware from a computer system. Malware is any number of viruses and software bits that intend to harm the computer or steal information, such as viruses, adware, rootkits, backdoors, hijackers, key loggers, spyware, trojans, and worms. Modern antivirus software employs several methods to detect and remove malware. However, no antivirus software can detect and prevent all possible malware.


Types of Antivirus Software

Norton AntiVirus

Norton is one of the most well-known antivirus software. One of its key features is that it updates every 5 to 15 minutes to make sure your system is up to date.


McAfee Virus Scan Plus

McAfee Virus Scan Plus is another software that shields your PC from viruses and spyware and includes a firewall that can help prevent hacker attacks to your system.


Trend Micro (“PC-Cillin”) Internet Security

Trend Micro provides an award-winning antivirus engine that protects from viruses, spam, spyware, trojans and other online security threats.


Bit Defender

Bit Defender offers protection from viruses, spyware, rootkits, provides anti-phishing help, and offers a gamer and laptop mode. This software is only $29.99 annually and can be used on up to three computers.


AVG Anti-Virus

AVG is unique in that is provides consumers with a completely free version. The free version works extremely well if you are just looking for simple antivirus protection without all the bells and whistles.
