I have been dealing with this scam on my Facebook:

Hi Everyone! 😀 A few days ago I saw an article on how you can get a brand new Samsung Galaxy S9 for 1$ if you live in Australia. You just need to answer 4 questions correctly! 🙂 It turns out that all you need to do is simply enter the code “TM9234KX” in Google and click on the first link in the results. Read this article to learn more. It’s very easy! 🙂 Yesterday, a courier brought me a package which contained the brand new Samsung Galaxy s9! Better hurry up, as the promotion ends today! 😀

I have run malawarebytes and bitdefender several times and my Facebook is still filled with this fake alert. How do I remove this?
