Norton 360 blocking all apps in windows 8.1

Soon after installing Norton 360-latest version, my windows 8.1 metro apps stopped working. can not open store, Mail , etc. none of the apps. seem to work. after struggling for some time, removed Norton 360 and now all apps are working.Disabling 360 firewall/antivirus did not help. Some one suggested it is to do with Norton blocking windos firewall and defender. Any solutio/workaround please?
