Hi Hope some one can help in this matter. When I am surfing certain sites ( No not port and torrent sites) and click on link to new page, I am directed to another page than intended by clicking the link. Most often to a commercial add site. I guess some mall ware is installed on my mac book Pro using OS X. How can I detect what file is installed on the Mac and how can I remove it? I have tried to reset Safari, but it didn't do the trick ? Br Mort.
