I am currently moving from an XP computer to one with Vista. Everything has gone smoothly and my Avast! Pro is working fine too, with one exception. When I exit Safe Zone the computer becomes unresponsive. Buttons and links don't work and eventually it says Windows Explorer is not responding. It tries to repair it but the indicator just keeps going around indefinitely and the only option is to turn it off at the wall. Once rebooted everything works fine again as long as I don't go to Safe Zone, which seems to work OK too. It is just when I leave it that I have the problem.
