As I tried to launch IE I started getting this error.  "wupdt.exe has completed an illegal operation" and windows gives it the boot.  I believe it is apart of the IMISERV virus.  What is it and how do you get it off your system?

Hi Iggy79,

There are way more virusses that use this filename, the most common is Gaobot.
Please boot into safe mode and do a full systemscan with your favorite virusscanner.
Or (also from safe mode, so you can be sure it's not started by default.

Another thing you can do is check the following registry entries:
Remove wupdt.exe in any case you find it. Then do a full virusscan in normal windows mode.
