Why do I need an antivirus software for my computer?

Antivirus softwares are programs that help protect my computer against most viruses, worms, Trojan horses, and other unwanted invaders that can make my computer "sick." Viruses, worms, and the like often perform malicious acts, such as deleting files, accessing personal data, or using my computer to attack other computers. To help keep my computer healthy, install F-PROT Antivirus. I must also ensure both the program and the virus signature files are up to date. These updates are generally available through my subscription.
