Windows 10 has this Malware Protection related file called “MpSigStub.exe”. There’s a Kasperky’s whitelisting page about that file, URLs are not allowed here but it can be found with the MD5 hash: ff2abb47b00130b31d128e191bff7c08
So it is a whitelisted clean file. Now that I have GlassWire set at Ask To Connect, this problem occurs: this file is created in a random folder such as C:\Windows\Temp\randomLettersAndNumbers\MpSigStub.exe
So I get the pop up Allow/Deny. It doesn’t matter which I choose because by the time I press either, the file’s folder is already deleted. The update installer has already given up. But then, after ~5 minutes, it runs again, in a new folder. So the previous Allow doesn’t help.
How to get past this problem? My suggestion would be this: a small arrow or something next to the Allow button. This arrow would open an advanced menu which would include something like “Allow this or identical file in any folder” (same hash would be adequate). That way, next time the updater runs, it is allowed regardless of the folder.
