A Strange ICQ Message

Today, I received a very strange ICQ message from one of my friend:

Hi, you've just received a postcard.

To view the postcard click this link or copy it to your browser's address bar.

The postcard will be kept for 10 weeks.

The link in the message points to an executable file named "postcard_flash.exe". Why does a postcard need to be executable? It most likely is a virus or a worm. From the Internet, I found some information about this kind of virus:

A very "clever" worm which spreads via email and ICQ messages. The worm tries to disable the firewall, as well as anti-virus program. Moreover, the worm changes the HOST file to prevent the compromised computer connecting to anti-virus and security web sites.... So what! I am using Linux.
