when i double click on the disk drives it does not open. i tried doing the steps mentioned above using attrib and delete autorun.inf, but even afer restarting the system the problem persists. please let me know the best possible solution.
you have already tried attrib & all those things but have tried third step...
after del autorun.inf you need to type mkdir autorun.inf so that virus cant create again, it will see that already one folder called autorun exist. Dont remove those folders after creating them in all drives using CMD. if not helping then try avg or USB disk security with crack on torrentz.com
