Cannot uninstall Avast

[Benjamin]

Hello,
My avast is activated (It is marked with a small red logo on my taskbar), and I can no longer activate it, so I decide to delete it again, but to no avail. I tried many methods, already there in various forums (with CCleaner, with the express to uninstall software, deleting files ...) but nothing works .
I do not know what to do, someone would have another idea?
Thank you in advance.

I tried in normal mode, then in diagnostic mode, and it makes me the same error:
The avast! Self protection module is enabled. For this reason, the operation can not be completed.
To complete the operation, either run this program from Windows Safe Mode, or disable the avast! Self Protection (via settings -> troubleshooting page).

Disconnect your Computer from the Internet before trying to uninstall. Good Luck.
