Basically you can eliminate this pestulant adware on a Windows machine by editing the hosts file. Search for a file named hosts (no extension) in your Windows directory, and open it with any text editor. On my Windows 2000 machine, this directory is C:\WINNT\SYSTEM32\DRIVERS\ETC.
I've added the following lines to my HOSTS file to block the Vibrantmedia ads:
127.0.0.1 itxt.vibrantmedia.com # vibrantmedia adware
127.0.0.1 devshed.us.intellitxt.com
127.0.0.1 vibrantmedia.com
127.0.0.1 intellitxt.com
