Thanks for the clear answer, kitto!
But note to Avast!: I've now deactivated the signature notice in my outgoing emails, BUT I'd be happy to include it if it was TEXT-ONLY! I read most email on my Android phone (as do many of my correspondents), and I BCC my mail to myself. When I get one of those emails, it always has a button "Show Pictures", even if the actual email is text only! It's only to get rid of that #$%^& graphic logo, that I've deactivated the whole Avast! signature notice.
Is there any way to make it a text-only notice?
