avast broke windows system backup servise

Avast Business Cloud Management Console & Clients
1

When Avast business is installed on Windows server 2008 r2, 2012, 2016 - windows backup service fails to make system state images.

example command
Wbadmin start systemstatebackup -backuptarget:e:
Error log:
Error in backup of C:\windows\systemroot\ during enumerate: Error [0x8007007b] The filename, directory name, or volume label syntax is incorrect.

It happens because of wrong file name in registry for Avast drivers:
c:\windows\systemroot\system32\drivers\aswvmm.sys
c:\windows\systemroot\system32\drivers\aswrvrt.sys

So it is impossible to use avast and, for example, Microsoft Data Protection Manager. Can it be fixed?

This is tracked in forum post https://forum.avast.com/index.php?topic=202568.0. Please report this fault with Avast support so that they know it is preventing normal server function. :slight_smile:

Report it to business support, not consumer support :wink:
