Spyware - Help!

Hi and thanks for any help you all can provide.

I currently can not get into windows at all, either through standard loading or through any of the safe mode options. 

What it does is right after the window screen appears I get two error messages.

First states that the application r DLL C:\windows\system32MSGINA.dll is not a valid Windows image.  Please check this against your installation diskette.

Second states lsass.exe - Bad file  The attributes of the specified mapping file for a section of memory cannot be read. 

It then proceeds to reboot its self and give the same error messages.

Thanks again for any help you can provide.

you won't be able to fix that one without reinstalling windows

Thanks!
