Email "postcard" virus

I assume it's a virus...I've not been stupid enough to actually click the link. It's typically an email claiming to be from "postcards@postcards.org" or something similar, with a subject like "You just received a postcard from a friend !"

I just got another one. It's supposed to look like this:

You can pick up your postcard at the following web address:

But note that the code actually looks like this:

<p align="left"><font color="#FF0000" size="2" face="Verdana">You can pick up your postcard at the following web address:</font></p><p align="left"><font color="#FFFFFF" size="2" face="Verdana">.</font></p><p align="left"><font size="3" face="Verdana"><A href="http://61.197.218.236/yamamoto/postcard.exe" target=_blank><strong>http://www.postcards4u.com/?a0190313376667</strong></A></font></p>

(Emphasis added.)

Sneaky, aren't they? A lot of the time you can't tell where a link is going in your email client until you click on it...
