Hi,Internet Explorer is constantly running in the background and I can't shut it down. I've tried to close it with the process manager but just re-opens. I think it may be some kind of spyware that keeps opening it but I can't detect any spyware using Norton and Windows Defender.This is a problem because I can't install Adobe software with it open. I have Vista Home and use Firefox as my default browser. I would like to know how to solve the problem or just uninstall IE which is proving to be not that simple with Vista.Any suggestions?
