content: I have Win10 and Cylance on one of my work PCs and it's literally a battle of malware vs malware.  Cylance was quarantining some Visual Studio web installation files, so I tried to kill Cylance temporarily (if you uninstall it, it won't reappear for a few minutes), but since Cylance was monitoring Cortona, I couldn't uninstall it without killing the Cortona process which is next to impossible, so I had to get my machine re-imaged to be able to install Visual Studio.
