Browser Hijacker Virus

A "Browser Hijacker Virus" is probably one of the least aggressive and destructive types of malware, but that doesn't mean you should allow it to exist on your computer. These things make unauthorized changes to your browser settings so that advertising or a similar page that's beneficial to the malware distributor is shown instead of the one you chose. This happened to me and twice I called Dell Tech Support, which is very expensive, and was told everything was fine and to ignore it.  I only use Google but it kept directing me to a third part site and I didn't like it but Dell refused to correct the problem.  It is very easy to correct so I'm attaching the web site for anyone interested.
