Anti-virus software
Antivirus software are computer programs that detect and remove virus programs. The term “antivirus” is used because the earliest examples were designed exclusively to combat computer viruses; however most modern antivirus software are now designed to tackle a wide range of threats, including worms, phishing attacks, rootkits, trojan horses and other malware like adware and spyware. Antivirus software typically uses two different approaches to accomplish this:
# examining (scanning) files to look for known viruses matching definitions in a virus dictionary, and
# identifying suspicious behavior from any computer program which might indicate infection.
The second approach is called heuristic analysis. Such analysis may include data captures, port monitoring and other techniques.
Most antivirus applications use both of these approaches, with an emphasis on the virus dictionary approach. Although some people consider network firewalls to be a type of antivirus software, this categorization is not correct.
The Purpose of Anti-Virus Software
A virus is a malicious program that is written with the intent of replicating itself by infecting your computer and passing itself onto other computers. Computer Viruses can be transmitted via email, networks, web sites, floppy disks, or CDROMs. They can open your computer to remote access, delete important files, and steal your passwords or identity. To combat and protect yourself from these threats you need Anti-virus software.
Common Features of Anti-Virus Programs
1. Preventing viruses from infecting your PC.
2. Detecting Viruses on Websites that you visit.
3. Detecting Email borne viruses.
4. Detecting Viruses on removable disks (CDs, floppies, USB devices)
5. Automatically update: All anti-virus products should check for updates to their virus definition databases automatically on a daily basis.
