How to make a computer virus in just 3 minutes

Take it easy, it’s just a prank!
In fact it’s about modifying a shutdown icon into a …”virus”.
To do this is necessarily to locate a shortcut which you believe the computer user is using it frequently. Let’s say Internet Explorer icon.
Right click on the shortcut, properties, into the Target field paste this:
shutdown -s -t 10 -c “WARNING! Your computer is infected and will shutdown!”, where 10 means 10 seconds. You can modify it as you wish. Right now you will need to put back the IE icon. Right click on it / properties / Change icon / Browse on C:/program files/internet explorer and click on IExplore / Open / OK / Apply.

Now, all the time when your friend is trying to access Internet Explorer by clicking on that icon, he will receive this message “WARNING! Your computer is infected and will shutdown!” and the computer really will shutdown in a couple of seconds.

But what is if you want to do not shutdown but restart?
For this you’ll write in the target field of the shortcut:
shutdown -r -t 10 -c “WARNING! Your computer is infected and will shutdown!”
“r” is coming from Restart, “s” from shutdown.

To stop the shutdown process write as fast as you can in START / run: shutdown -a

PS. I am not responsible for any arm, leg or fingers you get broken after this prank! :))
