After using Avast to get rid of the FBI/Moneypak virus, could not log into Vista due to above error 'rundll error loading wgsdgsdgdsgsd.exe' . The following solution worked;
I had the same exact error. Could not get past logon screen due to this 'wgsdgsdgdsgsd.exe module not found'. This was after I had cleaned the system using Avast antivirus. I did find an article on the web that provided the following steps;
1. Reboot, while rebooting hit F8
2. Select 'Safe mode with command prompt'
3. Logon and when you get the black command screen type 'regedit'
4. Navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
5. userinit parameter is supposed to be C:\Windows\system32\userinit.exe
6. 'Shell' parameter was pointing to the virus created;
"C:\ ProgramData\dsgsdgdsgdsgw.bat"
7. Modify this 'Shell' to be "Explorer.exe"
8. Reboot and that should fix the problem!
Try it!
