Auto run.Inf this is a instruction file associated with the Auto run function. It is a simple text configuration file that instructs the OS (operating system) which executable to start which icon to use which additional menu commands to make available etc Auto run.inf must be located in the root directory of a volume.That is CD,DVD,of Floppy Disk or Pen drive. It is mainly used by the manufacturer on what actions to taken when their CD-ROM when it is inserted. In OS, when autorun.inf is enabled (Normally by default it is enabled ) then by inserting the Cd or DVD the content of the medium is automatically executed. This is to avoid the user intervention and help the low level knowledge of computer literacy people. But Virus programmer taken this as advantage and make virus instruction in autorun.inf text file.

5 Quick Beginner-Friendly CSS Customizations That Make Your Blog Stand Out

By
Changing Background Color To change the background of your website, you first have to get familiar with the styling of the theme. Is the background color simply under body, or is it built into its own frame? Some themes are not as intuitive as others, so if the one you are currently using is intelligible, you might want to change to a different theme before you start editing. (The one I'm using in the example is the free  Catchbox Theme  and a very common starting theme is twentyeleven.) With most non full-width themes, the background color is simply under body. And overruling it is quite simple. 1 2 3 body {    background-color : #477C67 ; } You can use the  W3Schools HTML color picker  to get your colors, or install a Chrome extension, aFirefox plugin, or a WordPress plugin to speed things along when you're editing on the go. I chose a deep teal background color:  #477C67 : If this code snippet does not change the ba...
