You have seen many times ?Secured web site? or ?Your transaction on this page is secured? on your bank's web site, online merchants, governmental and other web pages.

What you probably did not understand is that even though the web site is in fact secure, this security does NOT extend to your computer.

Run pcAudit while on a secured web page and see for yourself that whatever you type while on a secured web page - CAN be seen by a hacker, unless your computer is protected.
