Anti-Malware False-positive or Real?

BCC · May 2023

We have multiple devices reporting this detection:

Virus infected SSI:N Type:Anti-Malware Signature Virus:Gen.Variant.MSILHeracles.cf775202 File:AD2F1837.HPPrinterControl_144.1.1068.0

Is this another false-positive or another distributed supply chain infection event?

I was just at the customers site and visited the ATP100 and have the same issue.

edit:
another one ip source (from one other my internal host): 209.197.3.8
I thinks is a false positive for windows update protocol, but i'm not sure.

As a follow up: No Hash value was shown.

I had to add a file pattern to the Anti-Malware allow list.
