I've a linux system on my laptop mostly for manually disinfecting USB pens from this and other similar infections.

Merely delete:

Autorun.inf
any .bat file that shouldn't be there
any hidden .exe or .cmd file that shouldn't be there
any folder named RECYCLED, RECYCLER, .TRASHES, .TRASH etc.
Job done.
Always worth looking in Autorun.inf before deleting it though just to make sure it's not referencing something else.
