Too slow *.exe files scanning with Avast QuickScan

Hi All!
I have recently experience some problems with scanning of .exe files in Avast 4.8 (Home), (Especially archived ones). The problem is that it takes way too much time: i.e ~10 minutes for a 2 MB rar archive. Is it OK?

Did you try the latest beta, if it makes any difference?

Hi Igor!
Thanks for reply!
I haven’t try it yet, but now I’m downloading it.
& One more question: will this beta automatically upgraded to a final one, when it will be available?

Yes.

That’s good news to hear 8)

UPD:
Just tried the new Beta, seems it solve my problems.
Thanks again.!
Chears, Take care. Rostyk
