This is a Joke file that displays an insulting message about the private part of infected users.

When infected, a warning message is displayed:
"Windows has detected that you may suffer from having a small penis. Is this correct?"
Underneath the message in the box are the YES and NO buttons. But whichever button you choose, the YES button will always be clicked. After clicking the YES button, the Joke file displays a maximized black window with a text message in the middle:
SMALL PENIS ALERT, in big red colored fonts. A "closed this now" button will be found in the window but it is not "clickable".
The only way to exit the program is by clicking the "X"(close) button in the
upper right hand corner of the window.
