Hi Please help me, My Computer was infected some worm which alters the autorun for the disk drives present on your computer. I got it removed but I don't know how to restore my autorun to its normal functioning! When I double click a drive it asks me which program to open it with so I have to always use the right click > open option. Kindly help me open my disk drives on double clicks. Please explain your response in detail

Read here: The AutoRun feature or the AutoPlay feature does not work when you insert a CD-ROM in the drive (http://support.microsoft.com/kb/330135)

You can also try to repair your OS, by restarting your PC with the XP operating systems disc in the CD-rom "boot from disc" and select the repair option.
