My Choice

My Windows 10 computer uses Avast. I find its catalog quite helpful. Everything, from file protection to email, P2P protection, and active internet protection is above average for any free antivirus system.

It’s lightweight and commendable malware detection capabilities make it quite a bargain. I use it in conjunction with Malwarebyte’s anti-malware scanner to bolster my system’s protection from zero-day malware.
