Thank you for all your help but I think I have a major problem as the only web page that will open up for me is the home page. It means I can't do any of the things you have asked me to do i.e.http://www.bleepingcomputer.com/combofix/how-to-use-combofix it won't open to let me read. I am using Lap Top to send this message to you so once again many thx
