Review article: 

Best Free Antivirus Software


This has full real-time capabilities, behavioral blocking features, script malware protection, and a low rate of false positives.


Default settings require certain user interaction. It is bundled with Chrome browser by default, and if not carefully avoided during installation the user may accidentally install OpenCandy (see discussion for clarification).

Runs as a stand-alone program on a user's computer
