Out of the blue today, I get a report that nobody can access the internet.
Whenever we attempt to open a webpage outside of our network, we get the following block reason:
While trying to retrieve the URL: Google
Error message: Failed to get scanner instance
This occurs on any page we try to go to.
I checked the logs, and the http content filter log gave the following error messages:

Turning off the antivirus scanner fixes the issue, rebooting does not.
We're running an Astaro Security Gateway 220 on version 7.501.
Thanks!
