Personal Digital Certificate problem

Hi guys,


I just bought a Y50-70 laptop with preinstalled Windows 8.1.


Everything's been working fine, but I've run into some problems trying to use my personal digital certificate. Namely, I can't use it either with Firefox or with Internet Explorer. It shows up in both as imported, but my electronic banking website and the national tax website don't seem to know it's there.


I phoned both my bank and the government agency in charge of issuing personal certificates, and pretty much ruled out web browser settings and firewalls as possible causes. But the guy at the government agency mentioned someone else having an identical problem, also with a Lenovo laptop running Windows 8.1. The certificate was successfully imported, but the websites didn't seem to register it.


Now, does anyone know of some Lenovo-related software or setting that could be causing the problem? Your help would be much appreciated.

Re: Personal Digital Certificate problem

hi De_Er,


Welcome to the Lenovo Forums.


If you haven't made any modifications yet on the PC, can you try the following:


1. Download and run the Mcafee Removal Tool

    - this will uninstalls the McAfee® Internet Security (30-day free trial) that's preloaded on the machine. When finished, try to install your personal digital certificate and see if it can now be detected. If this works, try to install your prefered antivirus software and observe.


2. If you're using the desktop version of I.E., enable Enterprise Mode and observe (requires Windows 8.1 Update).


3. Perform a clean boot

    - this is to temporarily disable non-microsoft apps running in the background that might be interfering with the web browsers.



Let me know how it goes.

Re: Personal Digital Certificate problem



I had a similar problem. I couldn’t use installed certificates on https pages.


I tried with clean boot and then it worked.


I found out that the process VisualDiscovery from SuperFish is causing this problem. If this process is disabled it works but I have to visit https page two times. First time browser just want to open the page and happens nothing.


Admin edit - inserted link to tool to remove superfish.


Try the uninstall too to check for and remove superfish / visual discovery
