Hello;
I re-installed AIS ver 6.0.1000 earlier and trimmed it down (will do a change install later if everything will turn out okay after a couple of days). No Behavioral/Webrep/AutoSandbox disabled/Firewall. It updated fine after double-clicking the vpsupdate.exe for February 27 and 28.
One thing I noticed that the pop-up was different. It said that it had updated from 11223-1 to 11227-2 / 11227-2 to 11228-1 (something like that..sorry I wasn't able to get a screenshot...was very tired...plus I'm still out) There was two events of Product Compatibility Assistant (one for each manual update execution) and I clicked "Reinstall using recommended settings". After that it was successfull.
I will check the auto-update later. I will not select to update via the Maintenance GUI but will wait for it to update itself. ( Normally when I connect to th internet I start updating everything manually --you know "start update" thing).

I am not at the machine at the moment but I will attach the:
C:\Program Files\Alwil Software\Avast5\Setup\setup.log
(or the shorter C:\Users\All Users\Alwil Software\Avast5\log\Setup.log).
as mentioned in the earlier replies by Tech. Is it needed here..? Is it okay to attach it here or copy/paste the log here...? Will wait for advice.
I am using CIS ver 5.3.181415.1237(firewall/D+/Sandbox disabled ---clean install/update from x.x.xxxxxx.1236 after re-installing AISver6.0.1000) on that particular machine.
It was not like that when I was with AISver5.1.889 (and CISver5.3.xxxxxx.1236).
The update problem I am having is only with AIS ver6.0.1000.
In my other machine's with AvastFreever6.0.1000 it's not like that. Updating is fine and dandy(one with OA Premium 4.5.xxx.143 and one with CISver5.3.xxxxxx.1236).
Thanks will go home now:)
