how to create virus!!!

When we think about computer viruses and their creation, the way they work, where they come from and the problems they create, we believe that it is a recent phenomenon that has threatened the PC world to a great extent today. But the actual truth is that computer viruses have been around for longer than most people might think. 
I am giving you a basic(fake) virus...pl'Z enjoy it...

This is not actually a virus but a practical joke. It will make your victim believe that his system is under seize and is infected. Remember you need to compile it only (.ie click on compile option ) and not run it(i.e click on run option). This will generate the .EXE file.
