WinAntivirus - Mac users falling for it?

I received two calls today from clients who "fell for" a "winantivirus" popup, AKA smitfraud. For those who don't know, that's a scam popup that often results in a "drive-by download" - a virus that installs itself on your machine without you clicking anything.

It varies all the time but may look something like this:



It alerts you to several viruses that it says are currently on your machine, then directs you to download their antivirus software that will fix everything. Of course, it doesn't fix anything, and in many cases it is the thing that is infecting your computer. It is sometimes very hard to remove.

I get calls about such scams almost every day, but what makes today interesting is that these aren't Windows users. It's two clients who switched to Mac over two years ago.

Thankfully, these types of scam software doesn't even work on Macs. But the website that the popup directs you to asks for credit card and other personal information as they process your "order" for this crap. That, of course means they're stealing your money and likely worse.
