Constant notification: Traffic has been blocked from this application: (svchost.exe)

I am having contant and annoying Symantec notifications that "Traffic has been blocked from this application: svchost.exe". I tried all the ideas posted in Jan 2011 after Soederftw complaints. I am running Windows 7 Professional SP1 and SEP Version 12.1.2015.2015.

Even though I really did not want to disable notifications, I tried to disable notifications but no luck.

Any other suggestions?

Thanks and Happy Holidays,

Moncho
