When I try to access my Gmail account (www.gmail.com) I get the message "Your connection is not secure" and there is no way to proceed.
Clicking on advanced gives the following information; gmail.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER
Clicking on SEC_ERROR_UNKNOWN_ISSUER provides the information below

Separate Security Issue, please update your Flash 28.0 r0 by removing it with this tool : https://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html If you use it Reinstall with Flash Player Version: 30.0.0.134 Current Version https://get.adobe.com/flashplayer/otherversions/ Step 1: Select Operating System Step 2: Select A Version (Firefox, . . . .) Note: Other software is offered in the download. <Windows Only>
What security Software are you running please as well please list your add-ons/Extensions ?
Removed the flash-player and reinstalled. It didn't help.
I am using Windows Defender on my work computer and Avast on my private, Having the same probelm on both.
No extensions used.
Plugins: OpenH264 Video Codec provided by Cisco Systems, Inc. Widevine Content Decryption Module provided by Google Inc.
Hi, Flash had nothing to do with your question as was clearly labelled : Separate Security Issue
So you have no Extensions/add-ons installed ?
Not sure of why on your Work Computer, is this a Home Office or are you in a Company as they may have separate security installed that your not aware of as Windows Defender is pretty bad choice to protect a business or their Firewall might block it also.
In your home : There is security software like Avast/AVG, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate. If you are running any of the above software please check their community forum for a work around to apply settings.
These pages are also for the errors you may have besides relating to the above.
