ATTENTION FACEBOOK USERS: If anyone posts a status to your wall saying anything about a dislike button, DO NOT CLICK IT ! It installs a virus called Virotrex which is used to redeem passwords and other sorts of information. RE-POST THIS TO KEEP EVERYONE SAFE !
This message, which is circulating rapidly around Facebook, warns users not to click on links in posts about a dislike button. According to the message, clicking these links will launch the Virotrex virus, which once installed, can steal passwords and other information from the infected computer. The message exhorts users to repost the information to help keep other users safe.
Thus, it is certainly true that Facebook users should be very cautious of any messages about supposed Dislike Buttons, even if they come from friends.
Because this warning contains information about a non-existent virus, and does not specify how such scams actually work, its value as a warning is questionable. To be of much use, security warnings need to be accurate, up-to-date and contain enough information to enable recipients to know how to effectively deal with the threat described if it should come their way.
