Traffic has been blocked from this application svchost.exe

Hi There,

We have recently installed SEPM  server SEP 12.1.2 and upgraded all the user computers using the Install package created from SEPM manager.

Most of the time randomly all the clients are getting a notification message "Traffic has been blocked from this application: (svchost.edvoxe)".

Can somebody please advise and give some solution to solve this problem. It will be very helpfull and highly appreaciated.

Thanks,

Cenil.
