Why do you have McAfee installed anywhere?
McAfee has started taking the approach of piggybacking on legitimate software, and having a checkbox to opt out. Easy enough, right? Not really... I had one instance of installing Flash I think it was, where unselecting McAfee also made the install button disappear, or something like that. I can't remember the exact problem, but I had to install McAfee to get what I wanted, then uninstall it later. Not a huge deal in the end, but HIGHLY irritating, and it put them permanently on my shit list. Any company that tries to put their crap on my my computer through subversion will never get my business, and I'll do everything in my power to make sure no one else uses them either :^S
