"Malware detected and requires attention" not listed in documentation.

Alerts for Threat Protection - Sophos Central Admin lists the alerts that can be generated and what to do about them, but I recently got an alert that doesn't explain what to do in the web UI or the email, and isn't in the documentation either.

The (redacted) alert text is as follows:

Malware 'Mal/Generic-R' detected in network location '\\sever\share\Downloads\file.exe' requires attention
