For some reason, almost everytime I left click on an Icon, Windows installer start and attempt to install Symantec Antivirus. I already have Symantec install and can't find out how to stop this behavior. I ran a virus scan (with Symantec), ran a spyware check and went back to a previous registry point. Nothing worked. Does any one have any idea what cause this and what I could do to stop this behavior?
Windows XP SP2
Thanks
