Spy Sweeper - Help! I would not recommend this to anyone!

For some strange reason, my son's PC (Windows 2000) about every 120 seconds and without provocation starts the Setup Wizard for Spy Sweeper. I cannot make this go away. I have contacted the developer and they are no help. After an hour, I have 30 ope windows asking to install. If I install, a close all the windows, after 120 seconds it opens again and says a version is running, do you want to close it and install again. This is worse tha the spy it is supposed to remove. I am close to running an fdsisk and posting a do not install this software on every forum I can find. Anyone have a solution to this? Email me at cstone@clarknexsen.com. Thanks, I will be forever in your debt. Webroot (the developer) can stick it!
