Blocking Network connections

I am using version 7.0.1.1426 Internet Security suite.
In an earlier version, the main front end page gave me an option to close all network connections, temporarily. That option is no longer available in the same place. Has it been eliminated altogether? If not, where has the option been moved to, please? I made regular use of it. I have alternative methods of locking down the network connections, but this was very convenient for me.
Thanks

You will find it when you right click on the avast tray icon.

It is “enable network lock”
