Blocking Adobe Autoupdate

Hi everybody I' ve realized that, once a week, my internet connection reaches the limit for a long period of time due to Adobe Autoupdates. I' ve tried to block this kind of traffic defining a rule that blocks internal traffic to a group of IP adresses, but I' m not sure that this is a good solution to solve this problema. Have you found an alternate way to block this type of traffic? Thankyou very much
