Are you sure because researching online Pirrit does exist...

Pirrit does exist. However, the developers of your antivirus app don’t seem to know basic details of how the operating system works. It is scanning read-only Apple system file locations. There are Apple Silicon firmware updates.

is it safe to say it was a false report?

Definitely

I haven't changed my Avast for Arm chips and its still on intel so..., I'm guessing thats the problem.

That's not the problem.

Yes.
