Repetitive "macOS Detected" notification

I am having the same issue Catalina 10.15.4, Parallels 15.1.4 (47270) and ClamXAV 3.0.15(8328)/0.101.4_02 1025.1036. Seems to happen only, while ClamXAV is touching certain Parallels-related files. It just stopped.
Hi, could you please create and provide us with the tech report as mentioned above?
 
It happens every time when my AntiVirus scans DeveloperDiskImage.dmg from xCode. And there are a few!..

I'm not sure why PD needs to constantly watch disk access, isn't that going to cause performance issues, surely!? That's a bigger issue than the annoying pop up "macOS Detected"...

Parallels devs: Could you please provide us with the option to "DISABLE DISK ACCESS WATCH", I would be quite happy to manually create VM without getting prompted by PD whenever I download an O/S image to improve performance and save the annoying pop ups.

I had almost the same problem. Turned out that sometimes antivirus and Parallels have some troubles working together. It happens because an antivirus sometimes may mistake Parallel's processes for malware. In this case, to prevent the antivirus from blocking Parallels Desktop processes, you just need to make a full virus scan and add Parallel's processes, which usually start from prl or parallels to a trusted list.

I doubt this is the case. It's more likely that Parallels watches file access constantly, and a file handle with an O/S image is opened, it then displays this silly message. When antivirus runs a full scan, it needs to open the file handles to scan the files, thus the message. I would be much happier if Parallels didn't watch my file access all the time, and an option for that be provided, but with the lack of their input, it appears that Parallels support doesn't frequent this forum much.

I sent a test report 325684916 on Nov 9, 2019
I sent you a new report now again 352187743.

You can replicate the issue yourself!!! Here are the steps:
install Xcode from appstore

then in finder, go to:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/13.1

copy DeveloperDiskImage.dmg onto your desktop.

Voi'la the pop up appears ("macOS detected; Click here to install macOS."). If you did these steps, you just simulated the same behaviour as when AntiVirus is scanning these very files.

Thanks a lot for the provided information. We've involved Parallels Engineering team in this case for the further issue investigation.

I have updated to 16.1.0 and can confirm that I am still having this issue.

I, too, can confirm that the problem still exists with 16.1.0 (48950) - maybe even worse than before the update.
FWIW: I recently (30 Sep) installed CleanMyMac X, configured to provide "malware and threat protection"; I thought that this might be significant based on information from other reports on this topic. Also, for years I have run Intego VirusBarrier without any problems, but maybe that has changed. (I will try turning them off one by one to see if that "fixes" it.)
 
Can you please remove that notification at all? It keeps appearing and never stops, which makes the software unusable.
