Over 25 years of virus-fighting experience

Since 1988, we’ve been working hard to fight viruses, spyware, worms, and other malicious software in order to protect our users. We’ve gotten ourselves an impressive reputation in the meantime, and we work hard to live up to it. And if you think we don’t? Just take advantage of our thirty-day, no questions asked refund policy.

Experts frequently certify and award us

We hate bragging, but we can see you insist! We get awarded and certified often, by numerous independent, industry-related organizations and testing agencies. They praise us for the virus detection capabilities of our software, as well as for not slowing down your PC.
