Mac mini: 'Malware Blocked' pop-ups for 'garad.wz

hello,

I'm on a mac mini m4 pro.

I constantly get popup messages regarding a "garad.wz": "Malware Blocked. "garadz.wz" was not opened because it contains malware. This action did not harm your Mac".

There's no startup action nor activity under that name, nor any file with the ".wz" suffix.

I have updated from 15.4 to 26.2 with the hope to see it fixed but it's still here.

Any advice?

Thank you!
