1. Check if your date and time is correct
One of the most common reasons your connection is not a secure message is the wrong date and time. Many websites use security certificates and each certificate has its own expiration date.
If the time or date on your PC is not correct, your browser may detect the required certificate as out of date, causing you to get this message.
However, you can easily fix the problem by updating the date and time. To do that in Windows 10, you need to follow these simple steps:
- Right-click the clock in the lower right corner and click Set Date/Time.
2. The date and time window appears. Deactivate the Set time automatically option.
3. Wait for a while and re-enable this option. You can also manually adjust the date and time by clicking the Change button.
If you don’t want to use the Settings app, you can adjust the date and time as follows:
- Press Windows Key + S and enter the date. Select Date & Time from the list of results.
2. When the Date and Time window opens, click the Change Date and Time button.
3. Now set the correct date and time and save the changes.
After you set the correct date, restart your browser and check if the problem is solved. If the date and time are wrong again, you may be having problems with time synchronization or with your computer’s battery.
2. Change your browser to Opera
Your connection is not secured. The error may be due to a problem with your browser, so changing your browser may resolve this issue.
And if you want to avoid security issues in the future, we recommend Opera. The browser comes with a blacklist of phishing and malware sites and will warn you if the website you requested is on that list.
Opera is also updated quite often, usually after every month. And speaking of security, why not add privacy protection?
The Opera browser is the only browser that comes with a built-in VPN that you can activate with just one click.
The VPN feature creates a layer of security by encrypting your internet connection, instantly hiding your browsing session from others.
Opera also detects and blocks those scripts or plugins that are considered insecure, and that even makes them safe for banking transactions.
3. Disable your antivirus software
If you want to protect yourself against online threats, it is important that you have antivirus software installed.
Although the use of an antivirus program is mandatory, some antivirus programs can sometimes disrupt your Internet connection and the message Your connection is not secure.
In addition to this message, your antivirus may also prevent you from accessing your favorite websites.
To fix the problem, you must first temporarily disable your antivirus software.
After that, try to access the problem website again. If the problem does not appear, it means that the problem was caused by your antivirus.
In most cases, the culprit is the SSL or HTTPS scanning feature. Therefore, we recommend that you check your antivirus settings and disable this feature completely.
Here’s how to disable SSL or HTTPS scanning in antivirus programs:
Users reported that this issue occurs when using ESET or BitDefender. To disable problematic features in ESET, do the following:
- In ESET, navigate to Advanced Settings.
- Expand the Web and Email section and select SSL.
- Now set the SSL protocol to Do not scan SSL protocol.
- Saving Changes.
- Open BitDefender.
- Go to Privacy Settings and click Disable SSL scanning.
- Open Avast.
- Go to Settings > Active Protection.
- Click Customize next to Web Shield.
- Uncheck the Enable HTTPS scanning option and click OK to save the changes.
- Open the Bullguard dashboard.
- Click Antivirus Settings > Navigation.
- Disable Show safe results for websites that give you the error.
- Open the Kaspersky panel.
- Click Settings in the lower right corner.
- Click Tools and then click Network.
- Now navigate to the section for scanning encrypted connections and check Do not scan encrypted connections. You can also go to the Advanced Settings section and click the Install Certificate button. Now follow the on-screen instructions to reinstall the certificate. We should mention that previous versions of Kaspersky do not have this option. Therefore, you should find and disable the Scan encrypted connections option.
- When you are done, restart your PC.
If your antivirus program does not have this feature available, you may need to uninstall your antivirus program and switch to another one.
As we wrote before, this issue occurs when using ESET or BitDefender, so if you change your antivirus program, we recommend Bullguard.
The tool offers real-time three-layer protection, signature scanning and all kinds of anomalies related to malware.
All detected malware is quarantined and then neutralized before the infection can begin.
Let’s look at some of its key features:
- Recognizes trusted apps and sites without errors.
- It comes with an improved firewall with extra layers of heavy duty protection against intruders and malware.
- Online protection for kids: uninterrupted games.
- Easy installation and free 24/7 expert support.
4. Delete cert8.db file
According to users, sometimes the message Your connection is not secure may appear if the cert8.db file is damaged. This file is responsible for storing certificates, but if the file is damaged, you must delete it.
We should mention that Firefox will recreate the file so you can delete it without any problems. To delete this file, do the following:
- Close Firefox completely.
- Press Windows key + R and enter %appdata%. Press Enter or click OK.
- When the Roaming folder opens, navigate to MozillaFirefoxProfiles.
- Select your profile folder and locate the cert8.db file. Delete the file.
5. Restart Firefox and check if the problem is solved.
Adguard is useful software that can prevent advertisements from appearing online. While this tool is great, sometimes it can interrupt your connection and the message Your connection is not secure.
According to users, you can easily fix this problem by disabling Adguard. To do that, you must first close Firefox completely.
Then close Adguard, wait a while and turn it back on. After that, restart Firefox and check if the problem is solved.
If the problem recurs, consider disabling Adguard permanently or switching to other ad blocking software.
6. Check your certificates
- Look for the (fake) Kaspersky Anti-Virus Personal Root Certificate.cer file. By default, depending on the software version, it should be located in the following folder:
C: Program dataKaspersky LabAVP16.0.0DataCert
If it can’t find the ProgramData folder, it should show hidden files and folders. To do that, just open File Explorer and click on the View tab and check the Hidden items option.
2.0Start Firefox and click the Menu button in the top right corner. Select Options from the menu.
3. In the right pane, click Advanced. Go to the Certificates tab and click the View Certificates button.
4. Now the list of certificates appears. Go to the AO Kaspersky Lab section and select Kaspersky Anti-Virus Personal Root. Click the Remove or Distrust button.
5. Follow the on-screen instructions to remove the certificate.
6. After removing the certificate, click the Import button. Locate the file Kaspersky Anti-Virus Personal Root Certificate.cer and follow the instructions to add it.
After adding a new Kaspersky certificate, check if the problem persists.
This solution only applies to Kaspersky, but if you use other antivirus software, you may be able to solve this problem using a similar method.
7. Install 32-bit version of Firefox
According to users, the message Your connection is not secure may appear if you are using the 64-bit version of Firefox with Kaspersky.
Apparently, certain versions of Kaspersky are not fully compatible with 64-bit versions of Firefox. To fix the problem, you need to uninstall the 64-bit version of Firefox and install the 32-bit version instead.
To see if you’re using the 64-bit version of Firefox, do the following:
- Click the menu button in the top right corner and click the question mark icon at the bottom.
2. Choose About Firefox from the menu.
3. You will now see the version of Firefox you are using. If you have a 64-bit version, uninstall Firefox and download the 32-bit version instead.
In addition to reinstalling Firefox, you can try updating both Firefox and your antivirus. According to users, this was an issue in previous versions of Kaspersky.
To resolve the issue, it is highly recommended that you update your antivirus program and check if that resolves the issue.
Keep in mind that this issue can affect other antivirus programs, so it’s important that you download and install the latest version of your antivirus software.
8. Restart your router
Sometimes the message Your connection is not secure may appear due to problems with your router. To fix these issues, all you need to do is reboot your router.
Follow these steps to reboot your router:
- Press the power button on your router (if you have a separate modem and router, you should also turn the modem off).
- Wait about 30 seconds after turning off your modem.
- Now press the power button again to start your router/modem.
- Please wait while the device boots up. After your router reboots, check if the problem persists.
This is a quick and easy fix, but it may not be permanent so you’ll need to repeat it if the problem recurs.
9. Reinstall certificates in Adguard
We mentioned in one of our previous solutions that Adguard can cause the message Your connection is not secured.
Several users reported that they solved the problem simply by reinstalling certificates in Adguard. This is a simple procedure and you can do it by following these steps:
- Close all open browsers.
- Open Adguard.
- Go to General Settings.
- Scroll down and click Reinstall Certificates.
After reinstalling the certificates, the problem should be completely resolved.
10. Disable Family Safety feature
Windows 10 allows you to use your Microsoft account to sign in to Windows. Thanks to this feature, you can protect your account with the Child Protection option.
This feature is great if you want to protect your family members from malicious websites.
However, this feature can also disrupt your Internet connection and cause the message Your connection is not secured.
To resolve this issue, you need to disable Family Safety by following these steps:
- Navigate to your family account with Microsoft.
- Sign in with your Microsoft account.
- Find the account you want to remove and click the Remove button. To delete an adult
- account, make sure to delete all child accounts first.
Then check if the problem is solved.
11. Check for malware
Sometimes malicious applications can change your system settings. As a result, the message Your connection is not secure may appear.
To resolve this issue, we recommend that you scan your PC for malware and remove any suspicious software. After the scan, check if the problem is completely resolved.
To do that, download Malwarebytes and install it, right-click on the application shortcut and choose Run as administrator from the menu. Let Malwarebytes scan your PC and remove all infected files.
After deleting the infected files, the problem should be fixed permanently. Keep in mind that you may need to run this solution from safe mode.
12. Bypass the warning
If you get the error message when you try to visit a trusted website, simply ignore the warning. To do this, follow these steps:
- When the message appears, click Advanced.
- Now click on Add exception.
- Click Confirm Security Exception. If you want, you can view more information about the problematic certificate by clicking the View button.
13. Change Fiddler settings
Users reported that this error occurs when using Fiddler. If you don’t use this service, you can skip this solution completely.
To fix this problem in Fiddler, do the following:
- Click Tools > Fiddler Options.
- Navigate to the HTTPS tab.
- Make sure the text says Certificates generated by the CertEnroll engine.
- Click Actions > Reset Certificates. Wait for the process to complete.
