The "Who Viewed Your Profile" Malicious Facebook Application
Once on the Facebook page, the Facebook application from the website untilr.co.cc, will display bogus information stating that a couple thousand persons "Like" and used the same application. This was done to persuade you into giving the application access to your profile. Now, if you click the "Continue" button on the same page, you will be requested to give access to the same application and the following message will appear: "Who viewed Your Profile is requesting permission to do the following."
But, whatever you do, please DO NOT allow the application access to your profile. If you are on the same page, click the "Don't Allow" button. Some anti-virus software will block the website www.untilr.co.cc, where the malicious application is stored.
