Why Use Free Antivirus Software?

Computer viruses; We all dread them. Most of us even have a horror story or two about the damage they've done. Dozens of antivirus programs exist, with varying prices and different levels of effectiveness. Only this Antivirus download however, offers total PC protection for free. It's not some stripped down version of a paid product: it's the real deal. Scan any drive or file. Get in-depth reports on viral activity. Detect suspicious files that behave like computer viruses do. Even scan compressed .zip files, where viruses often hide. All in one attractive user-friendly interface.

Antivirus also includes a mechanism for you, the user, to submit any files you find suspicious to the Safe List. Get immediate feedback on possibly viral files: have any other users submitted it? Or has it already been declared PC-friendly and landed on the Safe List? Instant feedback, from our security experts and other PC-users.

When used in conjunction with our Firewall, your PC is being protected by two powerful tools to repel, track down, or destroy viruses, trojans and spyware. It's a free two-tiered security system that exceeds even the big guys out there. It's real protection...at no cost.

Unique Antivirus Features:

Proactive "intelligent" protection intercepts unknown threats
Automatic updates for the most current virus protection
Easy to use interface lets you install and forget: no annoying pop-ups or false alarms
Isolation of all suspicious files eliminates the chance of PC contamination
Defense + technology constantly protects you

Antivirus's quarantine system takes all necessary precautions, recognizing that when it comes to protection from viruses, software should go a few steps beyond the usual. This Antivirus has been built with intelligence: it recognizes typical viral behavior. Antivirus, upon detecting a suspicious file that could be a virus, will immediately place that file in "Antivirus Jail": the file is blocked, awaiting trial. If it's a viral invader, delete it.
