My linux box scored 5/5.

Comodo antivirus for linux got 4. Bitdefender trafficlight got the phishing attempt.

There are then 3 more layers of protection:

(i) it is linux and most malware is irrelevant. Cross platform malware can apply, but I don’t have java or flash on the box, so that rules out most of that.

(ii) chromium seccompsandbox.

(iii) Apparmor mandatory access control enforced on chromium.
