Do you have a External hard drive ? You should back up your maps folders and anything else important. You need to Download CCleaner from FileHippo.com - Download Free Software Its a super website and its all great stuff. I tell many many people about it, You should run ccleaner everyday ! Also is windows firewall saying anything to you ? You might want to check your rig for any updates. Do you remember what the virus was named ? Sometimes you can google the name of it and find out what other people did to clear up the problem. You can restore your computer to a earlier state but most fags that make these viruses loop hole that because its what most people try to do first. You should start by searching your registry. Type in REGEDIT in the search box, Look for any new files that you dont recognize. Thats where i would start at first. Good luck buddy And a fresh install is only a last resort !
