2. Verify the Date and Time in Windows

Security certificates are used by our web browsers and computers to make sure a particular site is safe. Think of it as a form of ID. A website having a valid security certificate lets your browser know that the website claiming to be your bank is actually your bank, and so on. Just like our own government issued IDs have expiration dates, so do security certificates. If your computer has the wrong date and time set, this can cause certificates to appear invalid & your web browser will begin to issue security warnings.

If you notice that the Date and Time is continually incorrect even after manual adjustment,your machine may need to be serviced to replace its CMOS battery.

We need to be sure to clear all data, not just some of it.Temporary Internet files and website filesCheckedThis clears your cache, making your browser get a new copy of the webpage, images, etc. It's important to clear this to get a fresh copy the next time you visit, as the copy your browser has may simply be corrupt.Cookies and website dataCheckedCookies are how websites 'know' you when you visit them multiple times. This file can become corrupt, and simply downloading a new one can fix many problems.

3. HistoryCheckedWhile you browse Your browser will keep track of every page you visit, to try to make it easier to return. This can become corrupt due to modern active web pages.Download HistoryPersonal ChoiceThese are a list of files you've downloaded recently.

Checking this option does not delete the files you've downloaded, just the list the browser keeps.Form DataUncheckedInformation from entering forms online, such as your name, address, or other filled in information.

4. Security-Related Settings

There are multiple settings in Internet Explorer that protect you from malicious activity. While these settings should already be in the state we're advising you they should be in, it's always prudent to make sure these settings are correct, on the off-chance they were previously changed in the past.

1. Open Internet Explorer.
   

1. Select the Gear icon in the top-right corner, then select Internet options.
   

1. Select the Security tab at the top. Then, make sure Internet is selected for zone, and choose the Default level of Medium-high.
   

1. Select the Content tab at the top. Then, select Clear SSL state.
   

1. A box will open letting you know the SSL cache was cleared. Select OK.
   

1. Select the Advanced tab at the top. Scroll to the bottom of the long list of settings. Make sure Use TLS 1.0, Use TLS 1.1, and Use TLS 1.2 are checked. Then, select OK.
   

5. Try the Webpage Again

With your browser's website data removed, try to visit the website again. If you still receive security warnings, the issue is with the website itself, and not your device or its web browser. In this case, there is nothing you can do to resolve the error. Once the website owner/manager resolves the issue, you will stop receiving security warnings when you visit the website.
