all about virus and antivirus

Comodo Internet Security was developed to be a free, multi-layered security application that keeps hackers out and personal information in.
Built from the ground upwards with your security in mind, Internet Security offers 360° protection by combining powerful Antivirus protection, an enterprise class packet filtering firewall, and an advanced host intrusion prevention system called Defense+.
Unlike the stripped down versions of commercial software that other software vendors offer for free, this is the full, completely functional version of the product.
