A specific tool prevents the browser cleaning avast remove add-ons
When I answered yes to remove this tool, I have a window that opens "your browser does not appear to have additional modules a bad réputattion
So what? Thank you in advance
From what I understood from that translation I would say Avast Browser cleanup found an unneeded/unwanted browser plugin and offered to remove this. After this was done there were no additional plugins that needed cleaning up, so Avast's job is done. I think you're good and no other action is required.
To give you a better answer it would help if you elaborate a bit more what this "specific" tool's name was.
