I am running Windows XP Home SP3. Recently at startup and on return from hibernation I get an autorun which directs me to install the software which came with a WD eternal hard disk that I use for backup. I have never installed this software as I use Norton 360 to perform the backup. I have deleted the appropriate .exe files from the WD folder but the autorun problem persists, despite the autorun file not being found by the Windows search facility. The problem annoys me as it slows down the boot process. Can anyone help?
