Computer viruses come in all shapes and sizes. Most anti-viruses are guaranteed to detect suspicious files trying to install itself in the computer's system, but a few can find clever ways to get past the security block. It can wreak havoc on your computer's system damaging major functions and files. You'll start noticing unusual behaviors like getting error messages, or your computer starts to reboot or shuts down unexpectedly. These behaviors can be simulated to fool your friends to think that their computer has been infected. With a few steps you can program a fake computer virus that is totally harmless but will look and behave like the real thing.
- Program a fake virus that will reboot your system. Open your notepad and write down the following code, shutdown -r -t 5 -c "Your computer is diseased." The " -r" tells your computer system to restart or reboot, the " -t" command determines how much countdown time before system reboot, the number that follows the command in " -t 5" is the specified time in seconds you allot before the system automatically reboots. The number could be anything you want to specify like 10 seconds, in this example we put in a 5 second countdown. The " -c" command in the program, lets you create your custom error message, think of something that would alarm the owner of the computer.
- Save the program. Select file on your notepad and click "save as." On the dialogue box think of a file name that would catch a person's curiosity and compel that person to click on our little program. In this example we'll use "secrets", and then you need to append the name with ".bat", so you'll saving the program like this, secrets.bat. Click the save button.
- Test the fake computer virus. Click the shortcut or icon of the program you just saved to run the program. You'll get the custom error message you created and a countdown timer. At the end of the countdown your computer will automatically reboot.
- To stop the program select Start then click Run. You can stop the program from rebooting your computer by selecting Start then select Run. In the dialogue box type in "shutdown -a", this will prevent the program from continuing.
This fake computer virus is a harmless prank you can pull on your friends. Copy and transfer the file to their computer, hide it somewhere other than the desktop. Once it is hidden, right-click the file and choose "Send To" then select "Desktop (create shortcut). Go to the shortcut you created on the desktop then right-click it and select properties. On the Shortcut tab click the "Change Icon" button and choose an icon like the internet explorer icon. This will make it look like an innocent icon.
