Can we go back to the topic. :wink:
I decided to test the performance of MBSA with an older Avast prog installed.
If the Avast behaviour w.r.t. MBSA was changed over time,
then there should be no MBSA-problem with an older Avast prog.

Removed Avast in safe mode with aswClear.exe. Rebooted. Used CCleaner, also for registry.
Installed 6.0.1000, def.version 110223-0. Switched off autoupdate.
Did run MBSA → no problem !
Is this the proof ?

Then, let Avast update itself to 6.0.1289, def.version 111017-0.
Rebooted.
Did run MBSA → what a surprise, again no problem !!

Now, i’m finished. ???
