Query: McAffee is infuriating

I have used McAfee virus-scan for years.I am extremely irritated by them from time to time. Their program causes pop-up adds to periodically appear from my task-bar telling me that I can buy all sorts of upgrades and add-ons to their virusscan program for only $29.99. The pop ups ARE NOT browser windows. They come from the virusscan program itself. I do not want my computer to become an advertizing agent for them! Furthermore, I would like to be able to give powerpoint presentations to large audiences without having the pop-ups interrupting my talk.I have not been able to stop these pop-ups, and it pisses me off every time it happens. I just went to their customer support page, and they won't talk to me about this issue unless I pay them.
