3. Security certificate error 

Security Certificate (Security Certificate) is the center that keeps users safe from websites. The website owner uses a secure HTTPS connection to pay a third-party certificate authority (Certificate Authority) such as GoDaddy or Norton to obtain a valid certificate.

The browser will keep a list of legitimate CAs it believes in. When accessing a secure website and having a security certificate, users will not encounter any problems. In contrast, users will see an error about an unsafe website.

Sometimes this error may appear when the site administrator forgets to renew the certificate or has an attacker hacked into the site, the certificate may not check for the browser to warn users that it is not safe. In such cases, users should be cautious when accessing the site.

How to fix the certificate error

The most common cause of this error is that the computer's clock is turned off or displayed at the wrong time, because the certificate has a specific start and end date. For example, if the computer system displays in 2005, there will be no valid certificate for that time and cause a security certificate error. To edit the computer time, right click on the time in the system tray and click on Adjust date / time . The best way is to let Windows automatically set the time.

After editing the time, restart the computer. If the display time is wrong after restarting, the CMOS battery on the motherboard may be out of battery. This is a small clock battery on the computer, which allows the computer to keep track of the time even when it is turned off. Users should replace the battery but depending on the computer but how to replace the battery differently. Check Google for how to replace the battery for your computer model. However, this task is not easy, be careful when done.
