Installation of the beta 2 went without a problem.
Booting windows gives me the error twice.
No tray icon and can open the avastui, although avast seems to running otherwise correct.
Windows XP/SP3
Edit:
After rebooting twice, the problem is still there.
According to the start menu in windows, I have used the safezone while I haven't.
Taskmanager is showing two instances of avastui running. (both using up to 50% cpu)
Starting applications is really slow.
