Hey, I've faced this problem many times that is why I'm sharing it with you! The problem is that many time after removing virus from a removable drive (such a pen drive) we are unable to open it! i.e, explorer is prompting "OPEN WITH"! Here is the solution of this problem! -----------------------------------------------------------------------------------------> Simply go to DOS and then type the drive letter i.e, the drive path [If it it Removable disk (j: ) then type j: - Follow the total instruction below. c:\>j: <enter> j:\>attrib -s -h <enter> ------------ Now go to My Computer and right click on your removable drive and explore. There you will find a file named <autorun.inf> simply shift delete it! Then exit dos by EXIT command, Remove your drive and reinsert it, Now it is usable again! Thank You! Pankaj!
