As already noted many times, there is now a false-positive report in Windows Defender since the recent update (1,409.80 from 06/04/2024 or maybe a day or two earlier or later, depending upon when the update was pushed). This is definitely a false positive and I have reported it to Microsoft and am awaiting a response. There is nothing that I can do about this at the moment. To download and install FSUIPC7 (on Windows 11, 10 should be similar), you will have to temporarily allow this threat.
