Fool your friends, make it look like a critical system error has happened. Change the error message style, force the application to shut down your system, this will totally freak your friends out as they will think their PC has a virus. (This application is completely harmless).
The first (And Fairly basic) version of this app had over 15000 downloads worldwide so I thought it was time for a new version.
If you have any requests let me know via email. I will read them all!
