Autorun.inf Access Denied

Unfortunately that doesn't work either. I type in a command and hit enter and it simply brings up the next line as though I didn't even type anything at all. I don't know what it is about me, but 9/10 times when I try to solve technological issues following steps even a 3rd grader can follow, I have no success. I hit a dead end within literally 1-2 steps that make the attempt a failure. Basically, the standard, simplest solutions will probably not work. I even bought a program called Autorun Virus Remover to remove the file, but all I get when I attempt to use it is I/O error 103. Does it make a difference if I'm using the commands with E: drive instead of C: drive? I don't know why it would, but I can't really think of anything that's different from the normal case.
