Please HELP!!! virus problem?

recently for downloading crack file for warcraft 3 i went to one site( found it on search engine). along with files it gave me some trojans,spywares. my system was total mess. But after dealing with it for four hours and using 8 different antivirus softwares I comepletely removed it. but now my desktop backround has gone complete white, and if i try to set new picture as a backround it shows the following error. %26#123; cannot find 'file:///C:/windows/privacy_danger/index... I prefer not to format coz i have some important data stored.

Please HELP!!! virus problem?antivirus programs

now that the antivirus software has removed the virus, you still have lots of damage to repair. it's difficult, but not completely hopeless. the cleanest way is to save all your data on another media, reformat, reinstall, and then move your data back. 1st, though, you might try repairing your registry. there's software out there for that. good luck. you'll need it.
all the other answers are great,but i would just reload back to factory level 2 or 4 times,that way you be be sure your system is clean
Run an online scan with Trend Micro. They will remove it.
You downloaded one of those Bogus Anti-virus programs that throw fake warnings that your computer is infected with spy-ware, only to influence you to buy another program. Like what WDW said "Smitfraud" may help. Out of the 8 anti-virus software's you installed, was AVG one of them? I found AVG which is free to work effectively.
