Scammers are becoming pretty clever with a Facebook application which claims to enable a dislike button.
While the application doesn’t appear to harm users, it quietly updates their status without the user being aware. Users are then prompted to complete a quiz, which will eventually result in the user losing money after they enter their mobile phone number.
If you accidentally installed the fake application, click on the “account” button at the top right of the Facebook home screen. Navigate to the option that says “application settings,” and disable the fake “dislike” application.
If the app has posted to your Facebook wall, go to your profile page and delete those posts to stop the scam from spreading further. Mashable also recommends checking your “interests” and “likes” settings from the “edit my profile” menu, to be sure that the app hasn’t lodged itself there as well.
