Since three days, I have been facing problem using internet on my Microsoft Lumia 535 with windows 8.1 as OS. It was normal before that. I removed and put the battery back. Since then, it is showing a disclaimer that site's security certificate wasn't from a trusted certificate authority(Eventhough the site is safe and is with https protocol). It happens whenever I select a link from the address bar and when I try to login into my Stack exchange account.
It shows three options:
Go back to previous page.
Continue to website (not recommended).
Get more information
When I select option 2, it still redirects to previous page. I use Internet explorer as browser.
Is there a way to block these security certificate disclaimer?
Is this a virus or a malware entered into the mobile?
