at Magister: what version of Avast! ur using? the latest version 7.0.1426 should have solved the problem of faulty exclusions in the previous release.
if ur using the latest version, please proceed to try a repair of Avast!
if that does not work, i suggest
1. Download a fresh Avast! 7 package from

2. uninstalling Avast! the normal way with windows
3. run Avast! uninstall utility

5. reboot and go into safe mode once more, second time for Avast! 6 (if u updated from Avast! 6)
6. reboot again, this time to normal windows mode
