When you open your Internet explorer (the default browser), locate “tools” at the top bar, and here it goes:
Tools / Internet Options/ Programs and deselect the box at the bottom which says “Internet explorer should check…”.
Do this after you have installed the browser of your choice, Mozilla firefox alone or with Mozilla thundered (the Email client) is a great browser with a host of excellent features, tabbed browsing and easy bookmarking and integration with other sites as “Yahoo”. During the installation process please check that you “make firefox your default browser”. For free download of Firefox browser alone or with its Email client (which works pretty much like Outlook but is better) go to Cnet.com or http://www.mozilla.org and click “downloads”.
