Browser problem

I've been having problems from time to time with my browsers. Occasionally I will click a link or type in a web address but be redirected to a site like myspace instead. Other times the browser will give me an error message about not being able to find the site but I can go on another computer and access it immediately. Finally I got an error today telling me that I was trying to access a site on one server but instead I was being redirected to the investor.shareholder.com server. This has been happening for over a month but it has become slightly more annoying recently.

Thank you in advance for any help you can provide.

 

Yes. I've had the same problems with Chrome, Firefox and IE. The most common error is an invalid url screen, especially when clicking on a link. I can still access other websites though so it doesn't seem to be my internet connection. Generally if I wait awhile the problem goes away so I thought it was the individual sites but it happens too often and for too many sites. Then of course there are the random redirects to myspace or somewhere.
