What do you use to keep your system cleaned? I was using AVG (Free download) but it seemed to be causing insane amount of lag during raids so I decided to reinstall it because of the issues it, and my game seems to be back to normal.

How do you protect your computer?

Not every thread has to be 100% about WoW, but there surely are better forums on which to ask this question. This isn't even specifically about keyloggers or something. It's just "recommend me AV software, thanks."
