Katie,
I see it all here at work. We get all kinds of scams every day. Including viruses the claim to be updates to the virus definitions from symantec and McAffe.
Email with claims that everything from phone to your car will be shut of or impounded unless you pay them some amount they claim you owe them.
I have received a invoice for items the sender claims I bought but did not pay for.
lotsa fun stuff on the net.
