You can disable it but it isn’t recommended for obvious reasons. At least unplug yourself from the internet when you disable it.
Here is how to do it.
Open avast and go to settings → troubleshooting → untick enable avast! self-defense module and select yes when the confirmation dialog pops up. Now open Task Manager and close down any avast services and processes you have running.
To start avast! again, simply restart your computer. And don’t forget to re-enable the self-defense module.
