It used to be that every few months there would be a major update that required restarting one's computer. Now these seem to come almost once a week. Today I had to restart because of an update from a couple of days ago, and after restarting, a new update required that I restart a second time! This has become such an annoyance that I'm starting to look at other security programs. Can't the engineers figure out a way to avoid this - as they once did?
