I keep getting a pop-up on my W995 which says....'Certificate not valid for selected Web site, Continue with the secure connection?'. When i select 'Yes' or 'No', it disappears. When it first pops up, the 'Globe' symbol appears as if the phone is connecting to the internet. I've tried checking settings etc but cant find anything to stop it. This happens 10 to 20 times a day. Please help
