Your safest option, is to choose "NO" and then the unsecure items, or the entire page, won't be displayed.. On the other hand, since most such warnings are displayed on secure sites which require logons, you can make an educated guess the site is safe.
As with most computer things, it's always going to be your decision.
Hope this helps.
When I visit a page that pops up the message "this page contains both secure and nonsecure items. Do you want to display the insecure items?", how do I know if it is safe to proceed with "yes"?
The postings I've read on this topic all have to do with ways to get rid of this pop up, but I'd like to know if clicking yes is safe. I've read the KB articles on Microsoft as well but can't find answer to my question.
I am using Vista, IE7. Thanks!
