N360 does not detect PassShow AddIn
I use IE in Win 8.1. Two days ago I started getting a slew of advertising popups, some of which seemed legit but they were so extensive as to render IE unusable. However several of the links in the popups tried to download malware which N360 intercepted. I ran a Quick Scan and a Full Scan with no issues detected. Further research showed the PassShow AddIn installed. Once uninstalled the problem disappeared. My concern is that PassShow is clearly malware given its behaviour and yet N360 failed to detect it. Should this not be rectified?
