Whenever any .exe is run (Especially on start up, lots of them) I get an error saying
(The .exe run) – Bad Image
The application or DLL C:\WINDOWS\system32\wsg32.dll is not a valid Windows image. Please check this against your installation diskette.
wsg32.exe is virus, which I think was removed from my system recently I think the virus has changed settings so that when a .exe is run it notifys itself but now that the virus is gone wsg32.dll is no longer there. How do I fix this? Although I could be looking in totally the wrong direction, any help is appreciated 
Have a look at hijack this and see if wsg32.dll appears in it’s list. That MAY allow you to get rid off it.

Hiya, my PC was completely screwed: Adware, Spyware, Viruses – you name it. It was driving me crazy. Didn’t have anti-virus
.
The best way to fix software related errors is to get expert help, so I googled things and stumbled upon The Malware Forum on http://www.malwareremoval.com/ .
It’s a forum type thing and you get one-on-one help from a qualified person (certified by The MRU – Malware Removal University) to bring your PC back to a “pure state”.
It’s free too and covers everything. Easy instructions, you’d have to be extremely challanged not to be able to fix your PC this way. :p
The only fast solution is format and install Windows again
I second that, reformat or have some techies look at it and tell you the same thing.
