Just did a scan with AVG free edition and it says that user32.dll and ntoskrnl.exe have both been changed. I don't remember doing that so i can only assume it's malware of some sort

should I be worried? and how do i get them back to normal?

thanks for the reply, there doesn't seem to be anything odd in the event log

before i try that, I know I messed around with tcpip.sys before but I changed it back using a copy of the original. Is there anything I might have done or that a program might need regarding uxtheme.dll and that deleting it was cause problems?

I just tried it and it says 'Files that are required for Windows to run properly must be copied to the DLL cache, insert your Windows XP Professional Service Pack 2 CD now'

but it's already in

what have i done wrong?
