Sounds to me like a visit to the Control Panel, Programs and Features, and remove Google Toolbar, Mr Rivets.
I get exasperated by regular updates from Java and others that try, each time, to get me to tick "Install Something Else that You Really Don't Want". I got Google Toolbar that way, once even got Open Office Suite. No doubt laudable software but not wanted this time around.
I've just cleared out another load of toot that was slowing up the machine for no reason I could work out. iTunes I understand (it plays me soft and gentle music, somewhat distorted but bearable, while doing other stuff in here), but WHY do I need QuickTime? At my age, I don't do anything quickly.
