How to avoid Avast message in all emails

I have noticed I get this message on all my sent emails: (norwegian:)
“Denne e-posten har blitt sendt fra en virusfri datamaskin som er beskyttet av Avast”.
Translated- it says that “this email is sent from a computer free of virus, protected by Avast”

Is it possible to avoid this message?
Annoying to have this line before me own words…
I use avast free

If you have the latest version 11.1.2245 of avast - From the avastUI > Settings (cog wheel icon) > General > uncheck the ‘Enable Avast email signatures’ option
