This worm program behaves similarly to Happy99 Worm. It was originally spread by email. When the attached program file, PrettyPark.exe, is executed, it may display the 3D pipe screen saver.
Once the worm program is executed, it tries to email itself automatically every 30 minutes (or 30 minutes after it is loaded) to email addresses registered in your Internet address book.
It also tries to connect to an IRC server and join a specific IRC channel. The worm sends information to IRC every 30 seconds to keep itself connected, and to retrieve any commands from the IRC channel.
