postcard.exe

Today, there was a Christmas greeting message in my wife's inbox. We did not know the sender. Worst still, the message said there was a personalized e-card attached in a zip file. I checked the zip file that it contained a single file called postcard.exe. This surely was a Trojan horse or malware. To play safe, I had instructed my wife and my son not to open all attachments from someone they did not know.
