I had this happen once in the past and I managed to get rid of it but
can't remember how.
First make sure the computer is completely virus/malware-free:

If the machine is clean, manage your Startup matrix:
Start>Run>msconfig [enter]
This brings up the System Configuration Utility. Look on the Startup tab and
find the probable culprit. Uncheck the box next to its name, Apply and OK
out. You don't need to restart immediately, but the next time you do you'll
get a dialog saying you've used the Utility. Just tick the box that says in
effect, "don't bother me about this again".
Important - Do not use the System Configuration Utility to stop processes.
Instead, use Start>Run>services.msc [enter] and do not stop any services
unless you really, really know what you're doing.
