I didn't show it in the video, but I did enough preliminary work (placing the files in different places, etc), and no added definitions would be downloaded with the tweak in place that would add to PUP detection. The result would be identical.
Nice q.e.d. Thank you very much for sharing Would love to see all major AVs to boost up their PUP detection (especially those nasty Chinese, but I guess my AV of trust would not be willing to do that )
@Morvotron: Well WD on WIndows 8/8.1/10 definitely improve nowadays, meanwhile MSE only in Windows 7 contains the latest features of protection because Windows Defender on that OS is only focus on Anti-spyware based.
