Tuesday night at around 11pm my computer had this annoying "XP Antimalware 2010" thing pop up, it's obviously some type of virus, or adware so I tried to get rid of it. I think disabled AVG free virus checker because that hasn't been working since then too. After an hour of it being annoying I went to bed. I woke up today and I can't open anything but folders. Everytime I try I get this... "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item". So what the hell do I do? I have two accounts on the computer and it's only attacking the main one, the administration one, for now. Usually I only get adware things on the computer, those are easily found and deleted, but now I can't really do anything. Unless I plan on going folder to folder looking for it. I really don't want to reinstall Windows because I just did that like 6 months ago. Any help (besides saying "buy a Mac) would be great.
