Haldex

Haldex is a dialer that connects a compromised PC to the Internet by dialing high-cost phone numbers using a modem. It is designed to provide access to pornographic resources. The spyware can get into the computer while visiting many unsafe, mostly adult web sites. Haldex doesn't attempt to hide from the user, as it shows the computer tray icon, creates a desktop shortcut and Start menu group. The threat runs on every Windows startup.
