I received what I thought was an innocuous e-card today, but which turned out to be a scam email. Here is the text of the letter:
Hello,The problem is that the link redirects to another website via a hidden URL, and your computer is forced to download a file called postalcard.jpg.exe.
You have just received a postalcard from a friend of yours.You can download your postalcard from here:
visit E-Cards at http://www.E-Cards.net/
and enter your pickup code, which is: a0190313376667
(Your postalcard will be available for 60 days.)
This Trojan has been around a few months, but I was unaware of it until today. Be forewarned.
