The problem with NIS 21.6.0.32 & Windows 8.1

Hi all,

Norton Internet Security 21.6.0.32 has blocked the Windows Update service on my laptop with Windows 8.1 Pro 64-bit installed. It also makes my PC slow. It takes about 5 minutes for my PC to shutdown or reboot with NIS installed. After I uninstalled NIS, everything on my PC works normally again.

Please fix this issue ASAP.

Regards,
