I infected with the virus. but my Virus guard had detected it. how ever i cleaned it. it was an autorun.inf file. so i deleted it too.
But problem is when i try to choose show my hidden folder from folder options. it won't allow to change that. when i do show hidden file again it came back to do not show hidden folders. I think it is a virus. I want to remove without formatting. if u kn any solution let me know
thanx
