@DJSEA: Best antivirus ever: Sophos. With my uni account, I got a free (licensed) copy. It's the best because
1) It allows you to predefine an action to perform on infected files
2) It allows you to specify what types of files you want to search for
3) No updates unless you specify
4) NO POPUPS
5) Does not leave a resident copy of itself in memory, but rather an extention of itself that barely takes up any memory - that's a huge one. You've no idea how much cpu and ram Panda used to consume. Now, Reason and Live run faster.
6) The shred option - the best way to get rid of viruses. Note - it's not the same as deleting.
7) No extraneous bullshit - no fancy gui, no promotional popups and banners, no over-the-top functions.

A damn good scanner that doesn't miss anything on first scan. It doesn't give me 'the virus is unremovable. Would you like to start ___ after next reboot?" message. It finds a virus, and deletes it.
No, I'm not promoting sophos. It's just the first antivirus that I actually like.
