I have been working on computers for 11 years and this is the best program I have found at removing virus's and malware.  99% of the time that's the problem  with non loading IE pages.  You may want to try Google Chrome as well.  If you are stuck on IE also clear the cache by going to Tools>Internet Options and click the delete button in the middle of the first tab that will bring up the menu of what you want to delete.  if that doesn't fix it let me know I can help.
