This page displays live screenshots of Principal AntiVirus in action.

Protecting your computer against malware is as easy as clicking the Start button. It is recommended to allow Principal AntiVirus to startup automatically every time Windows is started.

Before a dangerous program causes damage to your computer, Principal  AntiVirus will block it and tell you how bad is the program you are running.

By clicking the details button when a dangerous program is blocked you can get  detailed program information and advice with motivated reasons why a program is thought to be a virus or other malware.

By recognizing real threats instead of virus signatures this software stays ahead of future malware and does not require subscriptions or regular updates.
