    Will this harm the computer at all?

    No, this only shuts the computer down. The user may lose any open and unsaved files, but the computer itself will be unharmed.

      Tips

      • It's even better if you name the virus after an internet browser like "Internet Explorer" or "Google Chrome" and change the icon to match. Save it to your desktop and delete the old internet shortcut so if they click to go on the internet, it shuts down on them.
        Thanks

      • Do not shutdown the computer too early. It may not scare the victim or may not look like a virus.

      • Android is based on Linux so with root access you should be able to do something similar (.sh files).

      • Once this virus has been clicked on, there is often no way to stop it. However, if you need to terminate the shutdown for whatever reason, go to command prompt and type in this following command: "shutdown /a". It will immediately terminate the fake virus.
        Thanks
