How to Fix Internet Explorer Security Certificates

Internet Explorer is a popular browser used for surfing the Internet, but it has its share of problems. One issue is with security certificates--a method of encrypting what you send over the Internet so criminals cannot steal your personal information, like credit card and social security numbers. Sometimes security certificates expire or prevent one from accessing a trusted website.

Instructions

1. Open Internet Explorer.

2. Click on "Tools" then scroll down and click on "Internet Options."

3. Click "Content" tab. Click on icon labeled "Certificates" under the "Certificates" heading (this is the second heading on this tab).

4. Click on the small right arrow on the right side of this window until you see "Untrusted Publishers." Then click on the certificate that is causing a error message.

5. Next, click "Remove" to delete that certificate.

6. Click "Close" and then "OK" once you are done deleting problem security certificates.

7. Exit Internet Explorer to reset the browser.

Tips & Warnings

• Make sure to exit Internet Explorer after deleting any problem security certificates.
