I don't know what happened but two days ago, my computer got like a virus and it is now seriously fucked up. I can't access the Internet, clicking on Firefox says "This application has failed to start because js3250.dll was not found. Re-installing the application may fix this problem." and IE just opens up a blank page. I get Windows Security Alerts. I can't do system restores, and when I try to access certain programs, it says "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator."
The only thing I have ever needed to do was system restore, but now I can't do that. I'm scared of telling my parents atm and I hope someone at TL can help me solve my problem before I have to tell them? I have also tried to re-install Windows XP, don't know if that helps, but it says I can't because my current version of Windows is newer than the one on the cd. And my PC is a Dell Dimension 8400 and I got it 2005.
