McAfee tells me I have an infected file. IT also tells me it can't be repaired. My pc is running sluggish and IE closes as soon as I open it. Here is the entire message. "McAfee has detected an infected file that cannot be repaired. Details Detection: vundo (Trojan), vundo (Trojan), vundo (Trojan), vundo (Trojan), vundo (Trojan), vundo (Trojan), vundo (Trojan) File Path: C:\WINDOWS\system32\khfDTjHA.dll More Info Trojan horses appear to be legitimate programs but can disrupt, damage, or provide unauthorized access to your computer." Normally I would just backup my files and reinstall windows. But I don't want to do that if I don't have to. Where can I start to solve this issue?

If you can get to c:\windows\system32 and delete that .dll file, that would be good. I would also run regedit and go to: [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run] Look for any malware there and the same in HKLM.
