avast internet security GUI freezes for one specific windows user account

Hi,
for one of the user accounts (my own) on our home PC the avast GUI freezes after being opened, ie the avast window shows but is non-responsive. Drastic reinstallation of avast seemed to help as long as I remained in the free, limited version, but as soon as I activated Avast internet security, the GUI started freezing again. For other users (wife, children, admin) on the same PC there is no problem.

Cause:
Avast GUI freezes immediatelly after opening when Holdkey (http://www.holdkey.eu/) is active

Solution:
Quit Holdkey is the only solution I found

Have you tried reversing the installation order of Avast and HoldKey ???

I use the portable version of holdkey
