Query: McAfee creates pop-up nightmare

Be forewarned that once your year's worth of free updating of virus files expires, McAfee ironically begins popping up repeat windows warning you of impending expiration, and then expiration, and this continues and even presents multiple pop-ups during one session. I've written them repeatedly and you might as well contact the Great Wall. I hate to switch but any company that does that to a paid customer exhibits brazen insensitivity to the whole spam nightmare. They're not the same company I thought they were, apparently.
