My Facebook Messenger keeps sending GIFS

[AC Question]

Ever since I started using my new Android phone (Samsung s6), I've been having issues with Facebook messenger. Its always showing the 'waiting on network' bar and on several occasions now my friends have complained about me spamming them with gifs when I have not sent any? Naturally I've tried installing and reinstalling but the problem persists.

Install Avast Mobile Security & Antivirus and run it at least overnight (the first run takes a long time). Then install Malwarebytes Anti-Malware and run it overnight.

It sounds as if you have some malware.
