Test suspicious files in Sandbox

Outsmart the smartest hackers with your own piece of DIY wizardry. Run apps, download files, and visit websites in a safe, isolated space first so they don't infect the rest of your PC.

Connect to real websites, not fakes

Pro Antivirus uses Real Site to encrypt your data and protect it from fake, password-thieving, money-grabbing, DNS-hijacking sites. Take that, dark internet forces.

Police your home network

Columbo would be proud. Pro Antivirus persistently investigates - and puts away - any potential threats to your router and your network.

Intelligent Antivirus
