Block ALL Network Traffic

I just purchased Avast Premium Security and am wondering if there is a way to change a setting to stop ALL data to and from the computer.
Kaspersky had a switch that you just clicked and it shutdown ALL traffic both in and out of the system.

Thanks!

Answered my own question but will post this if others want to know.

Menu > Settings > Troubleshooting > Enable Offline Mode. Click the box and any traffic between your system and outside world is cutoff.
