"ipu.exe" is a browser hijacker that loads popups for AdLogix.com
There is virtually NO information about this file in English anywhere on the
web.

Adlogix website has no information about this spyware or how to remove it.

NONE of the available Spyware removers or Popup Blockers detect or remove
it. Not Ad Aware, not Spybot Search & Destroy, not Pest Patrol, not Hijack
This. Nor Google Toolbar, Pop-up Stopper, etc.

It produces HUNDREDS of small popup windows. It is nefarious and must be
stopped.

You will know you have it by right clicking on one of the small IE windows
it produces and clicking Properties.
The URL will look something like this:
http://www.adlogix.com/servers/?Vxg.......

To stop it:
1. Close all browser windows (hah!!)
2. Do a Search>Files and Folders... type in 'ipu.exe' (no quotes)
3. The Search tool should find it in your system folder C:\Windows\System32\
or C:\Windows\System\
4. In Win 2000/NT, Use Ctrl+Alt+Del to launch Task Manager and go to
Processes and End IPU.EXE For Win 9x, you will probably need to restart in
Safe Mode.
5. Once you have stopped the application go to the folder where it resides
and DELETE it.
6. Removing it does NO HARM.
7. Write or call AdLogix at the following address and tell them thye are
doomed to suffer horrible disease and pestilence for their karmic crimes.
