About an year a go I installed an application on my pc which created an autorun. inf Folder. This folder was undeletable and uncostomizable acted as a file and it prevented the viruses from creating autorun files on the partitions including the USB Flash Memories. Now I cant remember what that application was, I still have the folder on my hard drives, although I changed my windows it still is undeletable and uncostomizable and cannot be copied, and I need it on my flash memory. Can any one till me what that app was? Or how to create such folder again? Or how to make an aoutorun file undeletable and uncustomizable on my Flash Memory? I'm really in need of it.
