I have had this problem before, but it just cropped up again yesterday. OS is Win98SE. Critical Update Notification displays the "new updates available" dialog right when I'm in the middle of something else. If I choose "Update Now" the update website scans and shows no new critical updates available. I haven't had this problem since my last clean install, and I should mention that our town was subjected to a massive power outage on Wednesday night while I was at my computer and online. So far the incorrect update reporting has occured twice since the outage. I'm thinking there's a connection, but I don't know what it may be. Scandisk showed no disk errors after the outage, BTW. Any ideas? I still have two months to go before this is a moot point and I can just disable it in task manager, or I could just disable it now and check only on update Tuesdays for the next two months - but I have a bad memory for things like that....
Also I should add that I did multiple Google searches and also searched this forum with no indication that anyone else has had this problem.
