Recognizing the 'Firefox security alert' Message for What It Is

Don't mistake the 'Firefox security alert' message for a genuine alert about the Firefox Internet browser. This fake security alert is caused by Trojans, engineered to deliver rogue anti-spyware programs into your computer. The 'Firefox security alert' message is the first step in many of the most widespread rogue anti-spyware program infections. Don't believe 'Firefox security alert's' message. Instead, use a genuine anti-malware tool to search your system for the Trojan causing the 'Firefox security alert' message. If you do this before it is too late, you may avoid a dangerous rogue anti-spyware program from invading your computer. The 'Firefox security alert' message may be difficult to differentiate from a real security application's warning messages. To make sure, you should always be skeptical about any suspicious alert messages coming from your computer. You should also always keep an anti-virus program at an appropriate sensibility rating to catch these kinds of infections before they manage to enter your computer.

What Makes the 'Firefox security alert' Message Appear on Your Computer?

There are two known causes of the 'Firefox security alert' message. Neither one is related to a genuine security alert about a problem with Firefox. In fact, this kind of error message has been known to occur with the Internet Explorer browser.

  1. The 'Firefox security alert' message is usually a typical pop-up window used by websites trying to sell you rogue anti-spyware programs. Rogue anti-spyware programs associated with fake alert messages are XP Security 2012, XP Antivirus 2012, Windows 7 Fix, Win 7 Security 2012, XP Antispyware 2012, Vista Security 2012, Windows 7 Recovery, Windows Accelerating Utility, Windows Accurate Protector, Windows Accidents Prevention, Windows 7 Repair, Windows 7 Total Security, Windows 7 Restore, and Vista Anti-virus 2012. These kinds of alerts usually don't indicate that your computer is infected. However, you should not click anywhere on these kinds of pop-up windows. In fact, the best measure is to close them directly from the Task Manager. The window may be designed so that the "X" on the corner is really a link, rather than the way to close the pop-up. It may also inject harmful software into your system by simply passing your mouse over it. To make sure, close your browser from the task manager, run a complete system scan with your anti-malware tool, and avoid visiting that website in the future. If you can, you should block the particular website that caused the 'Firefox security alert' message pop-up window.
  2. Most of the time, the 'Firefox security alert' message screen is displayed by a Trojan that is already on your computer. A Trojan may already have taken advantage of a security breach on your computer to infiltrate your system. There may be other background processes going on, with the 'Firefox security alert' message as the only visible sign of the Trojan infection. If you are seeing spikes in your memory usage, unknown processes on your task manager, or suspicious files that refuse to go away, you probably already have a Trojan attacking your computer.

Telling a Malicious 'Firefox security alert' Message Apart from the Real Thing

Real security alerts will never prompt you to download or install a specific program. The 'Firefox security alert' message displayed by a Trojan will usually be accompanied by another notification prompting you to download fake security software. This notification may look something like this:
We recommend you to install (or activate) anti-virus security software.
I do realize that visiting this site can cause harm to my computer.
Continue Unprotected/Get security software

You should never download or install software recommended by the 'Firefox security alert' message. These links take you to rogue anti-spyware programs. These kinds of malicious programs mimic legitimate security applications, while attacking your computer at the same time.Screenshot
