From Craig Schmugar:
Pretty Park Cleaner safely removes the PrettyPark virus from your computer.Pretty Park is a privacy invading worm. Every 30 seconds, it tries to e-mail itself to the e-mail addresses in your Microsoft Outlook address book. It has also been reported to connect your machine to a custom IRC channel for the purpose of retrieving passwords from your system. Pretty Park arrives as an e-mail attachment. Double clicking the PrettyPark.exe or Files32.exe program infects your computer. The Pretty Park Cleaner is very easy to use, and uninstalls itself upon completion. It does not however, protect your computer from further infection. It will, if applicable, show you a list of e-mail addresses that you sent the virus to.
