If the user clicks the fake 'dislike' button followed by a link, instead of installing a dislike button, the application uses the person's network to continue spreading the fake programme.
Facebook officials told that they are trying hard to block the fake 'dislike' button. They also told that Facebook don't have any official dislike button and asked the users not to click on the suspicious links.
"We're working hard to block and remove malicious applications that claim to provide dislike functionality and inadvertently update people's statuses," said Facebook spokesman.
Experts explained that these fake applications will steal information from users which can be sold to other parties. It will also affect user's social network contacts.
Installed the fake application can be disabled by clicking 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 application is posted to Facebook wall, users have to go to profile page and delete those posts to stop the scam from spreading further.
