I have AVG -- it stopped working, though. Some other stuff stopped working, too (Start -> Run -> regedit; closes after a few seconds). I think I screwed up my registry... my computer has been acting real funkly lately. It really, really lags, and I "uninstalled" AVG, but it's still there, but doesn't work unless I right-click and select "Scan with AVG", but that's not really much of any help.
I think it's time for another reformat.
Useless banter I felt like adding to the mix.
