Scold

Scold is a malicious computer worm which spreads via email in messages with infected attachments. Scold installs itself to the system after the user opens an attachment. It produces a picture to install itself unnoticed in the background. The Scold worm also uses the Microsoft Outlook mail program to send itself to addresses found in the Address Book. It doesn't delete or infect any files but does pose a security risk to PC safety and should be removed when detected.
