I just had to uninstall NS from a Windows 8.1 OS. Had not used it for a few days. Maybe some update didn't agree with my system. I could not get it to start. Rebooting did nothing. Action Center Showed NS as "snoozing" and I was unable to start it from there. Although Action Center said it was off, NS Firewall appeared to be working cuz my PC was stealthed and Windows FW was off. But protection was dead as a door nail. NS was listed in Task Manager but was using ZERO CPU.
Damn W 10 is screwing up a lot of security products as publishers mess with their programs to make them workable with W 10. Emisoft still can't get it's firewall fully functional and advises its users to use Windows Firewall with EMIS 10, Kaspersky IS 2016, which has a major vulnerability, as most a/vs do cuz how they scan https traffic (Kaspersky being the worst), still needs two more major patches to be fully functional (like have a working self protect module).
Installed Bit Defender Total Security 2015 MD. Seems to be working. But I have never had a BD product on my system that I didn't have to uninstall at some point. This year's product is a big improvement but I still refer to it as a great a/v engine housed in junk software. But at least for now it's fine and there have been no major issues reported in the latest BD version.
Windows 10 - Who needed it ???????????
