IE have lots of problems, and i personaly don't use it. My recommendation is to try one of the follwoing solutions below:
1- try to remove the add-ons that are installed in your IE coz many spywares are installed without your you knowing. Use the ad-on manager provided with IE6
2- Try upgrading to IE7 if you can not due to lisence limitations, there is a cracked edition in this site and there is also a crack and acivation tools for windows, search the site and this will help you.
3- Do not use microsoft products at all!!! To make it simple use opera or mozilla firefox. If you always hear about them and you think that people are joking; well no, start shifting to your favorite browser, They are both free and gets lots of support. I personally user oper for about 5 years, so i would like you to try it
Hope that helped in a way or another
