Don't Use Internet Explorer!

I would recommend firefox 4 (beta) or google chrome.
Firefox 4: https://www.mozilla.com/en-US/firefox/RC/?WT.mc_id=hp_1&WT.mc_ev=click
Chrome: http://www.google.com/chrome

I would advise you to learn about each browser and make an informed decision about which one to use
Here are some suggestions

1.You can download Windows Internet Explorer 9 from here:
http://windows.microsoft.com/en-US/internet-explorer/products/ie/home

2.For a fast and secure web browsing experience you can download Google Chrome: www.google.com/chrome
a. Another fast browser is Opera:
www.opera.com

3 For an even more secure experience use Mozilla Firefox:

Just copy and paste any of the links into your address bar. If you don't trust the links just google search for the web browsers listed.

1. perform browser reset. open IE . click on tools - internet options - advanced - reset.
2. goto add or remove programs and remove all tool bars. ( like google,yahoo.)
3. uninstall and reinstall security software.
