Regression of 0.4.10-dev-136-gc7eb46d, Antivir 6 deadlocks RtlpWaitForCriticalSection when "scanning the process list"

VBox 4.3.40
I found another regression
"Avira Antivir Personal 6.35.00.243" from http://www.oldversion.com/windows/avira-antivir-6-35-00-243

see av6-RegressionTest-NOSCAN.txt

Reproduction steps:
-install the app
-at end of setup select to not "show the readme.txt"
-at end of setup select to not "start an update"

Expected result:
the app very quickly does "scanning the process list" (very fast)
then it will start to scan the drive C
like in 0.4.10-dev-135-gffa94ca_okScans.webm
like in 0.4.10-dev-135-gffa94ca_okScans.log

Observed result:
the app hangs for 5minutes within "scanning the process list"
Each minute it will log, please note there is no filename in LoadLibraryExW()-call

(dll/win32/kernel32/client/loader.c:384) LoadLibraryExW(C:\Program Files\AntiVir PersonalEdition Classic\) failing with status c0000135

After exactly 5minutes of inactivity it will simply close the window and log
