What is the best free and easy antivirus you can download to your pc?
I think that Microsoft Internet Security is the best. I am using it and it works greathttp://windows.microsoft.com/en-us/windows/security-essentials-download
Kingsoft Antivirus. Guaranteed. And the best part is, it's as professional as a paid one, but it's permanently free.

I suggest AVG only because it is the one I use and it works for me no problems. :D
