USB drive's trojans

[t0rek]

This kind of trojans are so annoying, they infect your USB flash drive in the background. I have to deal with them very often, so I'm asking you guys two things:

1. AVG always detects them, so no problems here in my PC, but a few days ago I hit the cancel button (big and stupid mistake, I know) instead of the Heal button, after I plugged it. I realized that and I eliminated the trojan again, but it was too late. Now when I doubleclick the drive icon in the Explorer window it opens the "Open With..." dialog instead of going to the drive contents as normal. How I can fix this?

2. Is there anyway to inoculate my USB drive, so it can't get the same trojans again?

there is a registry modification you need to make, just google for it and it should come up, as to the usb flash drive, I advise you to install tweakui and disable autorun

Damn... i knew it was a registry thing. I just searched for it, but I can't find something useful, any clue about what I have to modify in the registry?
