Thanks for sharing us these procedures.
After successfully disabling Autoplay in your machine, it is also a good practice to first open your removable drive via command prompt and look for suspicious files using the command "attrib". Usually, malware files have the following attributes, or any combination of the following:
System
Hidden
Read-only
You may also check hidden folders using the command "dir /ah". I personally practice this since worm malware like the one described above will automatically execute by just merely opening the drive via Windows Explorer (even w/o Autoplay).
