Just to point out, the only thing that's different then is AIS has a 'Firewall' module where as the Free version does not.
You don't have 2 firewalls running do you?
I have two Windows machines; XP (Dell Laptop) and Akoya with Win7.
Before I get lectures about still using XP, I am one of the several million users that have programs that do not function in 7, 8.0 or 8.1.
That's why I purchased AVAST! Premium to help protect me.
I disabled Windows Firewall when I purchased and installed this new version of Avast in this Dell Laptop.
I also have MalwareBytes Pro installed, but that is not causing any conflicts with Avast because I disabled it, to establish which of these
two programs might be getting upset with each other.
From what I can tell so far, the culprit appears to be Outlook Express. Yes......... I know, I know, but who wins when you try to convert your wife to new ways of doing things. (No let's not go there) But yes OE seems to be the program that really gets AVAST all steamed up and stuck.
If you know of an email client that has the editing functionality of OE and is not going to upset Avast or my wife, please let me know :-))
