I don't know what's wrong with my computer but I think it's a virus. I can start the computer up but when I get to the main screen I can only move the mouse around; I can't click on anything nor can I right click. I tried booting up in Safe Mode and running Spybot, but it didn't find anything. Is there anything else I can do? I should have had antivirus protection but I didn't (I know it was stupid of me) so I can't run that. Is there anything I can do now or is it too late and do I have to system restore? I have a backup of the system, but it's about a month old and I would still lose a lot of information that I would like to keep. Any ideas?
