Thanks for the response Chemist.
I think I've knocked this one on the head myself after having a bit of a search around and reading up a bit on it. I had a bit of a play with combofix and mucked about with cmd.exe in safe mode and I'm pretty sure I've gotten rid of the autorun.inf files for good as well as the hidden lky.exe target file on all my drives (internal, external, thumbs and MP3 player!).
Thanks again though and carry on. Rest assured if I need further help I'll be back!
