Can't reach notwork while Norton Internet Security v22.7.1 running

Hi,

I am currently using Norton Internet Security 22.7.1. And when i installed it, all network reachability has crashed. After that i called Norton for support twice. Support Personnels could nothing even wtih remote desktop control both.

So, i set my network’s trust level to “FULL TRUSTED NET”, i have added some networking rules for permitting any connectionf from my network etc even tried to disable firewall but i had nothing. So, i compleately uninstalled NIS, and bum. I can reach my network again. But after a second reinstall, everything got worst again.

Please help me!!!
