Update:

I found this thread:
http://forum.avast.com/index.php?topic=10569.0

SpySweeper gave me those problems, not latest avast! iAVS update… I completely removed it from my system, anyway I didn’t like it that much, and I just started testing it since last week, have no licence…

I uninstalled avast! completely, rebooted, installed it again from the scratch, and rebooted again. Changed database value from ODBC to XML, configured it like it was before, and everything works perfect again… yeepee !!! Back on track !

Thanks for your inputs people ! I guess we can close this topic now… I’m in a big hurry, have service call, my boss will hang me… ;D See ya !!
