While upgrading the firmware on my HA stack of sophos XGS 3100, I got more than 70 email alerts for the HTTP virus detected Alert ID: 8001 with the messages below repeatedly:
Malware 'Unscannable' was detected and blocked in a download from crl4.digicert.com

Malware 'Unscannable' was detected and blocked in a download from ocsp.pki.goog
After the upgrade completed, the email alerts stopped.
Any ideas why this happened or what is happening?
