Hi Spec8472

i can confirm, the BSOD is caused by incompatibility between avast and Free Download Manager.

I deinstalled Free Download Manager and installed Avast AV NITRO Update - Finale Version [17.6.2310] from scratch.
No BSOD with Webshield activated. ;D

Thanks for your support.

It seems Free Download Manager is also updated in August, so the BSOD issue is created.
AVAST and Free Download Manager was in use for many months without this issue.

Thanks.
