Consider yourself one of the lucky ones. You've got the Internet-savvy to know that viruses are prowling the Web in record numbers. And you've got the technical-savvy to know how important antivirus protection is. But there's one thing you don't know.

Sadly, most antivirus providers give you more hype than science. And over time, this misguided emphasis permits the technology they sell you to become dangerously dated. At Comodo, we're committed to winning the battle against a plague of viruses that get smarter every year. We know that keeping pace with this enemy takes the kind of serious scientific effort that leads to the development of Next Generation Technology, not ever-glitzier marketing campaigns.Frankly, our relentless pursuit of technological advances leaves no time for hype.

While other antivirus software is still letting suspicious files enter your PC before it challenges them, Comodo's antivirus doesn't. Instead, Comodo's Development Team devised a one-of-a-kind Default Deny strategy worthy of its own US patent. It uses ultra-sensitive Auto-Sandboxing technology that stops, quarantines, observes and destroys any threat not found on its continually updated list of millions of "safe files."

Comodo Antivirus protection makes your PC impervious to viruses. The proof? Of the more than 40 million computers protected by Comodo Antivirus software, none have been adversely affected by a virus. Ever.

This is why Comodo is the only antivirus provider with the confidence to give you a $500 Virus-Free Guarantee: If your PC gets infected by a virus after Comodo Antivirus software is properly installed and registered, Comodo support technicians will restore it to working condition, or Comodo will cover up to $500 in repair costs.
