Appreciate any help.
If you click Help on the menu bar on the IE interface, what your Cipher
strength saying there?.

Some of them here:
C:\Documents and settings\Administrator\Cookies = index
C:\Documents and Settings\User\Cookies = index
C:\Documents and settings\User\User data = index
C:\Windows\Temp\Cookies =index
C:\Windows\Temp\History = index
C:\Windows\Temp\Temporary Internet Files\Content.IE5 = Index.dat
