One of my clients says many sites such as paypal, detect and give him a message that he is using an older browser (or a couple sites tell him to upgrade to Win 8). I had him check the "about" and it shows Internet Explorer 9.
This is what he gets from paypal: Update your browser: It looks like you're using an older browser that may have known security issues. Help protect your account Doing a search, I found this can happen if the website is not detecting the browser properly. paypal must be detecting it properly as I do not get the message with my I.E.9 I haven't been to his location to actually check what he has, just e-mails so far.
