sad :'(
Okay more seriously here is my view about that, but again that's just how I see it: if you find that the latest version of any software doesn't suite your needs anymore, then switch to another solution. Sticking to old versions is first frustrating, and second exposes your system to vulnerabilities with the time.
And finally, my post here is not innocent
I have issues with V6. I've spent the last couple of weeks installing and uninstalling while using something else in the meantime. I still have to decide...okay I know that V5 worked better on my system, but I would never go back to it.
ps: and on a side note, when you make any change to your setup, it updates with Avast servers, and you can't seriously expect them to keep an outdated software online.
