Spam type icons appearing on my second homescreen

Hi,

Not sure this is the best place as it isn't related to the specific phone. Hopefully someone can point me in the right direction. I am getting spam type icons (not pop-ups, definitely icons on the desktop) which I can delete but they re-appear after a couple of days. Also, they change, on a roughly daily basis.

If I click them, most seem to link to Google Play.

I assume there is some setting somewhere where I can opt out to prevent these appearing?...
