By the way, I didn't mention this before, but this version also has a problem when trying to add some programs to the exceptions list - Avast simply overrides the user's setting and removes the file (quarantine, if I recall correctly), despite the program's folder being added to the exceptions list. I had to recreate the whole list and basically not try to run the said program just to prevent Avast from removing it. Now I don't know how the AV acts when the program is AN ACTUAL malware, but disregarding user preference and flagging all kinds of things unrelated to true malware (it happened to me before for stuff that was 100% harmless) is starting to get on my nerves...
The usual excuse that free products come with such drawbacks compared to paid ones is simply not applicable here - if it's an AV it should flag actual malware and nothing else and obey user preference, WHATEVER that is (i.e. even if by any chance the excepted software is malware!). I thought that only big companies doublecrossing users to buy their buggy products defied users like this, but I see free products do that as well - not good!
