error after installing xp sp2

[Scott]

after I installed the XP service pack today and also the first time I
installed it two months ago. I found that ever time I logged in to some of
the sites I visit regularly the form redirection to a connection that is not
secure message kept coming up. even after I had turned of the form submittal
redirection setting in Internet explorer, which had always worked in the
past.

is this a new security feature or is there something wrong with Internet
explorer?

thanks,
Scott
