The e-greeting card scam is not a new one, but the FBI says it's returned with a vengeance.
It's Internet Crime Complaint Center is receiving an increasing number of complaints.
The fraud e-cards contain malware as an attachment, or it contains a link which sends the recipient to a web page where they can pick up viruses, keystroke loggers or other so-called trojan horse programs.
The e-cards sometimes even appear to be from legitimate e-card greeting web sites-- but the actual address of the links point to a numeric address, rather than one containing the name of the postcard company.
If you get one of these e-mails you can file a complaint on the FBI's web site, http://www.ic3.gov/.
