Question When ever I try to check emails on yahoo or msn the screen say Internet Explorer cannot display web page. How do I fix it.
Answer Here's your quick fix: use the Firefox browser, free from www.mozilla.org. I normally use Firefox because it is far more resistant to getting infected with evil programs such as the one that is keeping you from reading your email.
Since Microsoft won't let you use any browser except Internet Explorer (IE) on some parts of its website, you will need to also get rid of whatever is infecting your IE browser. An Internet security suite that includes protection from spyware should be able to solve your problem. Here's one that you can use for free during a two week trial period: F-Secure Internet Security, http://www.f-secure.com/home_user/support_and_downloads/evaluations/
If this doesn't work, please let me know and I'll tell you another, but more difficult, way to fix your browser.
