Remove an autorun virus

We will have to start the computer in safe mode. But before that, if you are frightened, pass here, if not, let's go.

Start you computer in safe mode 

Here, windows prevent your programs from running and runs only it's
trusted programs. Now, open the media with the autorun.inf file and delete the file normally (by right clicking and selecting delete in the drop down menu).

This does not normally fail but if it does, use these methods.
If you are successful, restart your PC to enjoy your favorite apps. 

Still has problems, you can contact me for more help
