I got all settings to "high". This doesn't do the trick. :'(
I mean, it works in general (pls. read this thread from the beginning), but occasionally it doesn't.
By "execute" I mean execute ;-) As in "start (an application)" or "run". Well, things you do with an executable file, really... ;-)
To get it all short and clear again in a nutshell, for the people that just zapped in:
1.) Avast works for me in general. Nicely, as it says on the tin.
2.) BUT: Aparently (maybe only happening to me, I don't know) the email scanner doesn't work. Instead of warning me of a virus in the attachement, it comes up with an empty scanning message (see screenshot above) and lets the email pass into my account without further actions.
3.)Now, if I save this attachement to disk, it rightfully detects the virus in it and offers to delete it.
(I just didn't try to execute these files yet, since I'm not sure whether it would detect it and prevent it from doing its evil virus work)
4.) If I export one of these mails that seak though the email scanner to an .eml file, avast appears and says that this email is suspicious, other than saying that there's a virus in it and which one. See screenshot above. (I assume it's the heuristics scanner!? Or maybe just the recognnition that it's an executable file.)
Maybe it's just a little bug, an overflow or something or why would the scanning pop up just be empty?
