I managed to install Sophos Anti-Virus for Linux on Clear Linux. It was not able to install Talpa out of the box on which I am not concerned as I prefer using Fanotify but I can not get Sophos to start using Fantofigy and I cannot find the recommended process to tell me if Clear has Fanotify enabled.
grep -ir FANOTIFY /boot/`uname -r`.config won't work as /boot is empty.
From installation:

Installing Sophos Anti-Virus....
Selecting appropriate kernel support...
When Sophos Anti-Virus starts, it updates itself to try to find a Sophos kernel interface module update. This might cause a significant delay.
Sophos Anti-Virus starts after installation.
Installation completed.
On-access scanning not available. It was not possible to obtain or build suitable kernel support because kernel headers are not installed.
