And they're causing slow PC, frozen screens, corrupt files and blue screen in epic proportion. This makes choosing an antivirus advanced enough to protect you from their plague absolutely vital! It takes an antivirus with Next Generation Technology. Technology that's based on solid science, not hollow hype. An antivirus engineered with step-ahead thinking.NEXT 

While other antivirus software actually lets suspicious files enter your PC before it challenges them, Comodo's antivirus never does. Instead, Comodo's 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." NEXT

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. NEXT

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.
