Fake Firefox Security Alert

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.
This fake security alert reports that a security scan is being performed, and after the fake scan, the pop up states that Firefox has found multiple infections on your computer and advises the user to download a security program to remove them. You should not click the "Start Protection" button located at the bottom right of this fake security alert, as this will lead to a rogue antivirus program being installed on your computer.
In most cases, this fake pop-up distributes a fake security program called Windows Security Center. Always use a legitimate security program to prevent these scams being displayed.
Fake Firefox security alert displays the following fake security warning message:
"Firefox security alert. Scanning of your system is currently on. Please wait until the end. Your system is affected by numerous virus attacks. Mozilla Firefox recommends you to install proper software to protect your computer."
