SSL Error preventing connection in Windows 10 - Potential Culprit Malwarebytes?

Hi,

Thank you for writing to Microsoft Community Forums.

Yes, third party applications can block port #443 which is a port number for the secure version of Hypertext Transfer Protocol (http) used to access web pages. I would suggest you uninstall Malwarebytes as you already have Avast
security and Windows defender which comes with Windows 10 to keep your computer safe.

If you are still not able to access the secure (https) websites, then follow the steps mentioned below:

Method 1: Check if SSL 2.0 and SSL 3.0 are enabled

1. Open Internet explorer (IE) and then click on tools menu.
2. Then go to Internet option.
3. Then go to Advance tab and click make sure Use SSL 2.0 and Use SSL 3.0 are checked.
   
4. Click on apply and then OK.

Method 2: Check the secure sockets layers (SSL) slate.

1. Open Internet explorer (IE) and then click on tools menu.
2. Then go to Internet option.
3. Then go to Content tab and click on Clear SSL State.
4. Click on Apply and then OK.

Method 3: Reset Security settings under trusted sites zones in internet explorer.

1. Open Internet Explorer (IE) and then click on tools menu.
2. Then go to Internet Options.
3. Go to Security tab and click on trusted sites. Then click on reset all zones to default level.
