Same here. Upgraded to 8.0.059 and encountered two problems:
1. Shutdown took 6 minutes, which was better than 8.0.020 (11 minutes) but much worst than 7.0.483 (about 30 seconds).
2. Updates ran hourly no matter what was selected, taking 100% of my CPU for 2 to 5 minutes each time.
Tried a clean uninstall and then editing the registry, etc., before reinstalling -- same problems. Contacted support, tried their suggestions, didn't help. They said they're aware of the problems and are working on them. So I did another clean uninstall and reverted to 7.0.483, which works pretty well on my computers. Only complaint is that I can't control the time of the updates, which always occur at about 9:30 a.m. regardless of the frequency I select, a very inconvenient time for me.
