There's nothing on this site that would cause your computer to do this. Dan isn't going to fix your computer if it's already acting up, and we don't have any malware on this site... hackers won't do something like this to individual users.
It's not Armor Games doing this to your computer. Mysql errors are common until we find all the bugs... and mysql is just a database of information, its not storing viruses to eat your account :P.
