Fake Firefox warnings lead to Scareware / Rogue Antivirus
Posted 09 June 2011 - 09:43 PM
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.

Safe Browsing has been in places since Chrome 10. I have been getting it warning me against sites for a while now. But the difference with chrome and the Firefox warning, Chrome really is warning you. the Firefox screen is a Malware ad.
Google has implemented the "Safe Browsing" feature in Chrome 12. These types of scarewares will appear on Chrome too.

Not installing in to Program Files is not a security issue, it's set up that way so that it is installed in UserLand, not a system folder. Plus, this way if you have Chrom einstalled, and if Person B in there own Account has it installed, all of the browser info is geared to just that user.
This is scary to see. And sometimes it is good to be using something that doesnt have a huge market share.. and for Munkypoo7 i can say that Chrome is growing and Google has yet to fix their security issue with it, as it doesnt install under Program Files folder.
