New "app" installed- but I didn't install anything?

AC Question

Hello. Recently I noticed my phone doing a download. I looked and it said new download complete for an app called "solitaire". Problem is, I never authorized a download of any new app. I dismissed the notification, then went to to look in my apps and solitaire is nowhere to be found. Yet every 2-3 hours I get the same notification from Solitaire "hi I'm your new app! Click to open". I'm thinking virus or something, I have not clicked on it, always dismissed it. How do I get rid of it?! There is seriously no Solitaire app anywhere on my phone. The only way I know it's there is from the notifications I get and they're seriously creeping me out. Help please??
