Yes, true.
Spybot S&D, Addaware, Adwatch and Sygate Firewall still installed!
(But thx for advice) 
But I still have some little Problems with Avast:
- How can I PERMANENTLY activate these “Main control” - Icons ?
Everytime I restart my System, they are gone again…
The Status Report reports the following:
IMPORTANT SUBSYSTEMS:
On-Access Protection: Ready and running
iAVS Update Center: Ready and running
Update interval: Default (Every 4 hours)
VPS Update Mode: NONE
Program Update Mode: NONE
On-Access Display startup key: Not Detected ← !!!
Mail Protection Proxy startup key: Not Detected ← !!!
How can I make Avast create these files?
Oh, another funny thing while install/deinstall-process of NAV/AVast was, that the script-blocking WAS active for the short time NAV-Files still existed…
