I see this notice translated into my local language - and it literally says to install the FreeBitco.in app. It's weird that it appears even though I've blocked pop-ups in browser options - I don't believe it's malware because I get no other pop-ups on any other site.
Hmmm, that seems different from mine.
Try checking and see where it leads you to. If it simply asks you to add the page to the home screen (should prompt), then it's legit.
Anything else like an APK or Play Store is definitely sus.
