TheFatAussieBarstard a IT shop owner and Youtube partner who makes comedy videos on YT talks about how to prevent viruses and remove viruses on a computer running Windows.
Antispyware and Antimalware Products which FAB mentions in the video.

Best video on Virus removal I ever saw mainly because FAB looks like some big Biker dude which breaks the stereotype of the geeky skinny techies. Plus, he is very funny in most of his videos.
