Thanx guys for your help. Actually I found it before your advise. I'm back with Avast 8. Avast 9 took LOTS of options/setting out of my hands. I don't like when somebody else decide for me what, when and how I want Avast to work for me. I'll monitor future development of this ONCE great software. If they will return to common sense and insanity, I will install a new version. Until then, I'm looking for replacement. Guys from Brno (AVG) are promising.
There must be something in the water in Dejvice, Prague............
