I have two computers (Home and office) that seem to possibly be infected.  Both are using Firefox 3.0.5.  My home computer uses Norton Internet Security, and the office uses 360.  Both are updated.  Over the past 3 days, I've had the following pop up:

 

Office computer:

 

 

The page says:

 

Warning!!! Your computer contains various signs of viruses and malware programs presence.

 

Your system requires immediate anti virus check! Antivirus 360 will perform a quick and free scanning of your PC for viruses and malicious programs.

 

Then tonight, my home computer pops up with this:

 

 

Warning!!! Your computer contains various signs of viruses and malware programs presence.

 

Your system requires immediate ani viruses check! Antivirus 360 will perform a quick and free scanning of your PC for viruses and malicious programs.

 


 

at the bottom left, it reads:   Transferring data from advancedprotectionscanner.com

 

I killed Firefox instead of hitting the "OK" or "Cancel" buttons (Didn't trust either). 

 

I've searched Symantec's site, but I can't find anything related to what I'm seeing.  I've done Google searches and found some sites and some discussions talking about this one, but nothing from Symantec.  I can't imagine I'm on the cutting edge of a new virus.  Either way, is Symantec aware of this, and what can I do?
