MessengerBlocker

MessengerBlocker is a rogue spyware removal tool designed to trick users into purchasing its full rogue version. MessengerBlocker may get onto your machine with the help of Trojans, through browser security exploits and other illicit mechanisms. At the beginning MessengerBlocker will offer you its free trial version for seven days but after this it will start its nasty work. MessengerBlocker will display fake security alerts claiming that your system is in serious risk and that you must buy MessengerBlocker because only this software will be able to fix all the problems. This is the way how they seek to lure users into purchasing MessengerBlocker's full commercial version.
