A new threat has surfaced which specifically targets Mozilla Firefox browser. This "scareware" detects your user-string from your browser and if you are using Firefox, it will display a fake alert stating that a security scan is in process, with a button recommending that you Start Protection.
If you click on the Start Protection. button, it will proceed to install a rogue antivirus software on your Windows computer. This rogue will "detect" a fake virus and ask you cough up $80 to remove it.
Internet Explorer users get the standard "My Computer" dialog that appears to do a system scan inside their browser window.
If you see such an alert, simply close the tab.
Cybercriminals use such scareware tactics to scare people into downloading malicious software onto their computers and/or pay for a fake rogue antivirus.
