Recently my pendrive was used in some other computer and after that it shows presence of a new file named "autorun.inf" and now the image of the removable drive (i.e., the pendrive) has changed in "my computer" page. Earlier the image of the removable drive looked like a small tablet, now it looks like an open folder in "my computer" page. I cannot delete the file "autorun.inf" in usual way and I am getting a message saying that this is being used. My own antivirus is a bit old and is not updated due to lack of active internet connection. Is there any way I can still get rid of this .inf file without having active interconnection with my computer? What problem can this file create in future?
