On Windows XP reinstallation as a component IE 7 too was installed. Immediately after installation I tried it. It worked fine. I also tried Firefox and GoogleChrome. After that there were several updates including IE which I updated along with SP3. Now IE 7 does not work. I cannot connect to internet through IE. But I can use Firefox or GoogleChrome without any problem. Why is it not working? My reason for re-installation of OS was due to repeated problems due to _Anti-spyware program - "bestantivirusscan.com" Do you think it is possible that program is still there hidden even after clean re-installation of the OS causing IE not to work? What is the best way available for me to get IE 7 work again? Thanks
