I, like a few of us here, were some how fucking retarded enough to download 4chan fandango, and even MORE RETARDED to click the fucking OK button at start up. Well here is how I got rid of it. I don't know 100% for sure if it's all gone, but my computer seems to be fairly normal.
Here is a nice little list of how I approached this problem.
1. Said "FUCK" and facepalmmed.
2. clicked ok (if you haven't done that THEN DON'T)
2.1 went to start-up and deleted "WinUsrDat32" or something similar
2.2. Shut off the computer right away when the background changed(just held the power button)
3. Reinstalled windows/system restore (from startup, f10 for me)
4. Made a linux live CD of Ubuntu
5. backed up my files to my USB through ubuntu
5.5. deleted "4chan fandango" from C:/program files
NOTE: If you can't get Ubuntu, then press f8 a whole shit load on start up, and select safe-mode and do all this instead.
6. Logged on with an administrative account
7. Copied important documents from the old account to some folder on C:/
8. made a new account(admin account)
9. Deleted the old one (I clicked delete the files, just to be safe)
10. Went onto the new account and ran a virus scan with the Norton 60 trial I got, (updated it first though)
11. Went to tools->folder options->view tab and uncheck "Hide hidden files" and "Hide system files"
12. (shift+del)Deleted Star.ico, hacked.swf,5 .vbe files(close.vbe,etc.) from C:/
13. Ran CCleaner
13.5 Deleted ALL files made on Jul/13/08 or modified.
14. Checked for updates at http://update.microsoft.com
And I think that's it. If I remember something, I'll post it. I still can't use System Restore though so I don't know what the hell is up with that, so I may still have it.
