Malware pop-up

Hi!

I've got the same issue here with my MacBook Pro 2019. Since yesterday I keep getting the notification that "CleanParameterd" will damage my computer, but I can't seem to find this file anywhere on my MacBook. When I click on the "show in finder" button, it doesn't do anything but close and open again. I've deleted all my downloads and Apps but the problem stays.

Anyone knows how to handle this? I've also tried a hard reset and installed IOS Big Sur, just in case. An option would be to use Time Machine but I'd rather use that one when I'm out of options.

Please help me out!
