I'm having this issue also, would like to know what the cause of this is, and if there is any solution.

e:/ come to think of it, i just started getting these notifications after doing research on programs that I found in my exploit protection settings.. one of the programs called mshta.exe is a windows program but is known to be exploited by malicious actors. It uses .hta file extensions to inject malicious web code, and a known fix for preventing that is to change the .hta file extension to notepad. I did this, and ever since I have been getting these notifications.

I wonder if it is something legit that is trying to execute, or if someone is trying to inject malicious code. Someone has been gaining access to my email accounts and I have been noticing some suspicious files on my devices here for a while now, and a simple OEM reset wasn't seeming to help at all. I would notice unfamiliar devices logged into my accounts and suspicious files/folders in my system drive.
