Since I updated avast! to version 5.1.889 (from on my Win7 64bit Lenovo Thinkpad, i have the following problem:
When locking the system ("Windows-Key"-"L") or after "Sleep-Mode" no login window to Windows is displayed any more ... only the Windows7 background image (of login) is shown.
The only thing i can do in this situation is a brutal shutdown of the system (power button or removing power)  :(

The login window is normally displayed by the Lenovo Fingerprint Software (i am using the current version, since it combines "normal" login and fingerprint based login.

But if I disable the behavior shield of avast!, the login window is displayed and fully functional.
So there is a conflict between the current avast! version, more concrete with the behavoir shield.
(my shield settings are: all options checked and action: ask)

Is this conflict known or has anybody the same problem?  ???

[UPDATE 2011-02-24]
The same problem still occures with version 6.0.1000  :-[

I ran into this on my wife's Thinkpad with W7 x64. I had to use system restore to get the update back out of the system, then turn off behaviour monitoring , and finally reinstall the update.

FWIW I have the behaviour monitoring disabled on all our PCs now as it has caused various problems on every one of them. Most are XP though.
