Cannot browse local or remote sites with any browser, FTP and email works fine

This is my original post. I am hoping to get this resolved quickly and
I apologize for the cross posting.

Problem: Web browser (IE) will not connect to any site. Internal or
external. Tried firefox and opera as well and all I get is "web site
found" but the site never loads. Tried localhost for my Apache server
no luck.

However, FTP connection and email work just fine.

Solutions tried:

Checked router, modem, etc.
Restarted
Checked connection with another computer and another install on same
machine. They work.
Started in Safe mode (I am using it now) and it works fine.

Anyone has a solution?

Thank you very, very much.
