OK but the question I still have is this. 550 coexisted fine with AVG, no problems. Attempting to upgrade jv16PT version from 550 to 552 triggered the AVG intervention.
You noted previously that:
"The problem most likely with AVG is that the 3rd party executable protection program just got updated prior the 552 release, after the guys and galls of AVG have had enough time to study it they should be able to fix the problem, i.e. not to report it as a virus."
Now, if this was the cause of the problem, would we not have the same issue with 550? But you will see on this thread and others that all who have had the failure with 552 have reverted to 550 successfully, with no AVG intervention on that older version.
So, the bottom line seems to be that AVG 8.5 has no issue with 550, but it does with 552. This seems to indicate that the issue was not AVG updating their 3rd party executable protection program, but that something changed between 550 and 552 which triggered their intervention, regardless of any updates they may or may not have made to their system.
Or am I reading this wrong?
