Principal AntiVirus defends against a range of malware, including viruses, spyware and trojans, without relying on signature scanners or constant updates. It guards against current and future threats.

One of the software's key features is its ability to intercept threats before they become active, without constantly checking all incoming and outgoing data against known virus footprints. Instead, Principal AntiVirus scrutinizes dangerous programs that are starting for the first time. Before such a program causes any harm to your computer, Principal AntiVirus will block it and let you know just how bad the program is, along with offering advice on how best to proceed.
If you need more information about why a running program is suspicious, you can request a detailed motivation from Principal AntiVirus. And if you're running a program that is deliberately dangerous, you can tell Principal AntiVirus to trust it forever.
Aside from the threat interception process, another great feature of Principal AntiVirus is its efficiency. By remaining in a dormant state and only coming into action when a dangerous event is triggered, this software runs faster and more efficiently than other antivirus software on the market.
Lastly, it's also worth noting that Principal AntiVirus is compatible with Windows XP, 2003 and 2000, making it a suitable option for a wide range of users. In conclusion, if you're in need of a reliable antivirus software that can protect your computer against all manner of threats, Principal AntiVirus is an excellent choice.
