Facebook Users Beware of 'Dislike' Button Scam

Facebook members are cautioned to avoid clicking on a link that purportedly offers users easy access to a 'dislike' button.

If you are one of the hundreds of millions of people around the world on Facebook, you might want to use caution before clicking on a new application or link on the social-networking site.

British-based computer security firm Sophos is warning of a Facebook scam inviting users to install a "dislike" button.

The scam tricks users into allowing a rogue application to access their profile page, which then posts spam messages and spreads itself by inviting the person's Facebook friends to get the button.

The application also attempts to dupe users into completing an online survey.

Sophos says the "dislike" button is the latest in a string of Facebook scams, including links purporting to lead to funny or shocking video.

Facebook already features a "like" button for users to indicate they approve of something on another friend's page, usually a comment, post or photo.

The "like" feature has prompted many on Facebook to call for a "dislike" option to counter it, making the option to have a "dislike" button useful to scammers.

The "dislike" button and other scams often show up in wall posts from the person's Facebook friends, whose pages have already been infected.
