To test whether it's something saved in your settings, could you do a two-minute experiment?

Create a new Firefox profile

A new profile will have your system-installed plugins (e.g., Flash) and extensions (e.g., security suite toolbars), but no themes, other extensions, or other customizations. It also should have completely fresh settings databases and a fresh cache folder.

Exit Firefox and start up in the Profile Manager using Start > search box (or Run):

firefox.exe -P

Any time you want to switch profiles, exit Firefox and return to this dialog.

You'll click the Create Profile button. I recommend using the default location suggested, and to avoid data loss, not re-using any existing folder. Then start Firefox in the new profile you created.

Does DNS work as expected in the new profile?

When returning to the Profile Manager, you might be tempted to use the Delete Profile button. But... it's a bit too easy to accidentally delete your "real" profile, so I recommend resisting the temptation. If you do want to clean up later, I suggest making a backup of all your profiles first in case something were to go wrong.

I assumed from the phrasing of your question that Internet Explorer is working properly. If IE is not working properly either, you might have a hosts file entry with the old address, or a similar routing rule in other software or your internet router.

Thank you jscher2000 for all your suggestions. I did the profile thing and it still came back with the redirect.

I then tried your IE experiment and that too come up with the redirect.

So all 3 browsers are being redirected even after the flushDNS and cleaning out all the cookies,history, etc.

I have HOSTMAN and I did look at my hosts file but didn't see anything related to that website.

I do have a router though.

Do you have any other suggestions / experiments I could do to narrow this down.

Once again thank you for your thoughtful help and suggestions.

Do you want to try bypassing your ISP by changing DNS servers? You could try OpenDNS or Google Public DNS. One way to change this is at the Windows level (in the TCP/IP properties dialog), and another is in your router. Something more temporary would be to change your IE connection settings (I think it's under LAN Settings). However, the details are beyond what I can look up at the moment.

Thanks again jscher2000 for all your help.

The PROBLEM is NOW SOLVED !

I have CCleaner... which I did use prior to coming on here and requesting help. Well, this time I checked "clean compacted databases" and that seems to have done the trick. I am not exactly sure why... maybe you and someone else has a more technical answer for that... but obviously it was pulling information from those databases every time it went to that website. Something to remember when we come across a similar problem.

Thanks again for all your help. It was greatly appreciated.
