There is a company called Jeetyet Media that emails a virus to people that takes over the users browser windows and pushes the website pages to the left so that it can insert its own ads to the right of the page. I have not authorized these people to use my websites for their advertising and I am wondering how I can get this to stop in the Firefox browser. This should be illegal as I have not authorized any use of my website for someone elses advertising. These people are hacking my websites for their profit.
