What is Fake Firefox SecurityAlert?

Firefox security alert is a fake pop-up message created by Internet criminals with the intention of distributing fake antivirus programs. These rogue pop-up messages are incorporated into misleading websites and target computer users who are inadvertently directed to them. Although the alert reports that your computer is infected, the software has no method of detecting infections that may exist on your PC. The messages generated are designed to scare PC users into downloading rogue antivirus programs in order to eliminate these non existent security threats.
