JPEGScan is a small, fast and easy-to-use scanner that has detection and repair capabilities for JPEG files infected with the MS04-028 exploit.

JPEGScan can detect all known variants of the exploit, and accomplishes this not by string searching or anti-viral signature scanning but rather by properly walking through all blocks in the JPEG searching for the undersized boundaries in comment sections that indicates the presence of MS04-028 infection.

Repairing renders the file harmless by readjusting undersized boundaries to their proper size, and if the file was based on a real JPEG then it should also become viewable.

If you simply want infected files deleted rather than repaired, JPEGScan can handle that also.

JPEGScan also allows for one-click integration into Explorer's context menu, allowing you to easily right-click on any file, directory or drive and start scanning immediately for infected JPEG images.

Although all users will find this tool useful, network administrators in particular will enjoy being able to sweep entire networks for infected images. For reasons of speed, optimization and accuracy, the main scan routines were written in assembly language, making JPEGScan basically as fast as it possibly can be
