Note: this may only work in windows 2000 OS's
easiest way to get rid of specific anoying programs is hit ctrl alt delete and click processes, alternatively go control panel - admin tools - services
find which process is causing you the problem, then either
A: search for the process name on your computer, end it in task manager then delete it.
B: right click the process in "services" then make it manual start, i would not reccomend disabled.
hope this helps.
