Internet users who receive an e-card in the next few weeks might
want to think twice before opening it. I just received an ecard from postcards4u.com, but it was a virus.
Windows users who follow the web link visit a website which exploits vulnerabilities in Microsoft's software and installs the Clsldr-D Trojan horse onto their computer alongside other malicious code.
Here is more info about it.

The ip the card was sent from is 193.64.1.141.
