Megabyte - thank you for jarring my memory. There is an inftating PNG mod: http://www.sarc.com/avcenter/security/Content/6366.html

Mike - you are the first I've heard of this.

To everyone else: We all know the joy of turning on our machines and see what's changed online or for new e-mails since we last checked, but before reading e-mails or websites, give your AV scan time to download the latest defs before hoofing along the web... A def that's a day or 2 newer can make a difference.

Other tips - like Dave S stated above - PLEASE TURN OFF the PREVIEW PANE. It's the worst thing in the world as it allows any malignant code to launch right away. Also make certain that your anti-virus package is integrated into your e-mail package...

Here is the info on that worm...

Microsoft Internet Explorer PNG Deflate Heap Corruption Vulnerability
Risk
High

Date Discovered
12-12-2002

Description

A heap corruption vulnerability has been reported for Microsoft Internet Explorer.

The vulnerability is related to the way that Microsoft Internet Explorer interprets PNG image data. The function that handles the deflation of PNG images does not properly handle some invalid data within PNG image files.

An attacker can exploit this vulnerability by tricking a user into viewing a maliciously constructed PNG image file. When the image file is rendered it will trigger the heap corruption condition and overwrite critical areas in memory. Any malicious attacker-supplied code will be executed with elevated privileges.

It should be noted that applications which depend on MSIE to render PNG files are also affected.
