Malware Overview

This worm arrives via email messages spammed by another malware or by a malicious user. It may also be dropped by other malware.

Instead of attaching copies of itself to email messages, this worm asks users to click a link in the message. This is an effective way for it to bypass email applications that scan for malicious attachments.

When a user clicks the said link, this worm connects to certain Web sites to download a copy of itself.

This worm drops copies of itself.

It creates registry entries to enable its automatic execution at every system startup. It also modifies a registry entry to enable its automatic execution at every system startup.
