Despite the whitelisting and AV exclusions, some versions of Sophos antivirus might still cause issues, including BSOD (Blue Screen of Death) events with the Teramind Network Driver (tm_filter).

We expect this to be resolved once Sophos releases a fix.

In the meantime, we have introduced a few workarounds.

The Agent will now detect if Sophos is installed on a user's computer and disable the Network monitoring to avoid any conflicts with the AV.

Additionally, a notification, Network monitoring is disabled due to interference with "Sophos Antivirus" will be shown on the Notifications report for the affected computer. A pop-up message will also be shown at the bottom of the screen, Network monitoring is disabled for some computers due to interference with "Sophos Antivirus".

If contacted, our support team will provide you with instructions on how to install a special version of Sophos.

Due to a bug, a Websites-based Activity rule with an Except condition for the Webpage Url criterion and a Block action like the one below would close the browser even if the user opened an empty tab/window:

As the user would be unable to enter any URL on the address bar, this would prevent them from browsing any sites without taking special steps (e.g., Continue where you left off option).

The bug is fixed now.
