A free, small, fast and easy-to-use scanner that has detection and repair capabilities for JPEG files infected files

On September 14 2004, Nick DeBaggis discovered a buffer overrun vulnerability in gdiplus.dll - a library used by many common applications (including most Microsoft applications) for viewing JPEG images. Subsequent analysis by the eEye team confirmed that the vulnerability could be exploited to execute arbitrary code, allowing an attacker to gain control of a remote system simply by enticing the victim to look at a specially-crafted JPEG image. MS04-028 is the tracking code assigned by Microsoft to this specific vulnerability. If the program used to view the JPEG file uses a vulnerable version of gdiplus.dll then yes, and unfortunately a lot of software is affected.
