Vundo and its mutated clones: Vundo.b, Vundo.celldorado also silently downloads aditional files from the Internet and runs arbitrary potentially harmful files, mostly adware components.
Vundo is distributed by e-mail in messages containing links to insecure web sites, which exploit certain security vulnerabilities of the Internet Explorer web browser. Once the user clicks on such a link, Internet Explorer opens a dangerous site that automatically installs the Vundo trojan into the system without user knowledge and consent.
Vundo is responsible for the severe decrease of the amount of system virtual memory available. This results in noticeable computer performance slowdowns. Vundo secretly runs on every Windows startup.

The Vundo virus I had unchecked the "automatically detect DNS server" and added two bogus entries. Rechecking the box got rid of a redirection to an antivirus site.
