UE 5.5 Virus?

When I went to installed the Unreal Engine 5.5 version (on a Mac), my anti-virus program flagged this file: “C5NG1616603GDHHU10D2KF3LILF… OSX/Pirrit.ext”. Did anyone else get a virus flag? Does the 5.5.1 version still install this file? And does it still have a virus?

Hello there @L.D.22!

Just tested the update, no antivirus prompts encountered. I would suggest to scan your system for any possible threath. If everything’s clear, please removing all versions of UE, and reinstall.

Thanks for replying

Well I just tried installing the 5.5.1 version and had the same virus alert! I guess I will stay with the 5.4.4 version until the 6 version comes out. Maybe the virus won’t be in that one.

I have this same issue on my windows 11 pc. Did you ever figure this out? I even checked on many third part malware checkers and they all said Unreal Engine 5.5.1 was malicious. Maybe there is a bug or virus they accidentally overlooked?
