Well I spoke too soon. I noticed that it took much longer for my internet to connect, and for Online Armor to load, so I uninstalled the Behavior Shield, thinking that may have something to do with it. I also uninstalled the P2P, Mail, and IM shields, since I don't use them. Upon reboot, OA didn't load at all. I tried to open CCleaner to uninstall it, to see if it is still a problem, despite adding Avast! to it's exclusions and vice-versa. CCleaner failed to open, I got the same error about the path being invalid and not existing or something. Then that error message froze, and my whole computer froze up. Then the screen went black except for my cursor, probably explorer.exe crashing. I hard-booted my computer, and everything loaded fine. Not sure what to do...
EDIT: I just realized I added OA to Avast!s scan exclusion, not the File Shield exclusion. Restarted and everything's still okay for now. Problem here, problem gone, make up your mind!
