WHEN ARE THE RESTARTS ENDING???

My pc this morning when starting apparently decided to load that 21.1 thing, all when i was in email, possibly no protection as the norton icon was gone. Like many I dont like the new boxes and stuff, but my biggest complaine is that it is now demanding my FOURTH restart - when is this ending? I have manually invoked L.UPD this morning and restarted twice, then I rans a full scan later, in which it did live update, loading 2 more updates, then demanded a restart after the scan. Is this done yet?
