Windows 10: Certificate security

I have noticed my computers are acting weird. Anti-malware has been run on both computers. My laptop started a download called "ELERA". This is said to be a touch pad driver however this is not the case. My desktop has an usual traffic as well there, applications are opening on there own and produce no debug code. They are listed as background task. I am using glasswire as a traffic monitor. This has notified me that there are well over 200 hosts processes running. These processes are not listed as those of the country I am in. My browser is the only authorized vpn I use. Among all of this I ran a test. Using both the glasswire firewall and the windows firewall. I blocked all traffic. Both in and out. There was still communication in and out of the computer. Then the computer reset to default. I have done a clean install on the computer. There is still the same issue. I have done a clean install with new hard drive the issue still persist. The application that are opening and closing have expired certificates. Is there anyway to verify this traffic to narrow down where the information leak is?

security certificate

Hi,

Thank you for posting your query on Microsoft Community.

I would like to know if this issue occur on Different Web browsers too?

I would suggest you to try the following steps, when you access secured website you may get this error message.

1. Open Internet Explorer and verify that the page you are trying to view is listing a certificate error.

2. To clear the certificate error goes to Tools --> Internet Options from the menu of IE 11.

3. Click on the advanced tab and scroll down to the security section. Clear the boxes for: "Check for publisher's certificate revocation" and "Check for server certificate revocation".

4. Click Apply and Ok.

5. Attempt to reload the page by clicking the Refresh button at the end of the address bar or by pressing the F5 key. Your page should now load as expected.

This error can be cause by the SSL certificate of the website – maybe it was not issued by a trusted Certification Authority on the client side. It could even be an attempt to fool you or intercept data you send to the server. Or maybe the certificate has
expired.

I suggest you to refer to the Microsoft help article and check if it helps.

e60 & Security Certificates

When Mail for Exchange connects to a server using a secure connection, it is best if the device has the same root certificate installed that has been used to issue the server certificate. Otherwise the device will prompt the user about an untrusted certificate
every time a connection is made to the server. This may happen several times daily, sometimes only minutes between.

Nokia devices come with many certificates pre-installed. These can be viewed by using Menu-Tools-Settings-Security-Certif._management. If a certificate issued by one of these certificates is used on the server, no additional certificates are required on the
device.

If a certificate that can not be validated with the device’s pre-installed certificates is used, for example a certificate that has been self-created, the root certificate that has been used to issue the server certificate must be installed on all devices the
administrator deploys.

In the case of a self-signed server certificate, the root certificate is the same as the server certificate since there is no certificate chain. The server certificate is the one that should be installed.

Before installation the administrator must convert the certificate to a format the Nokia device supports.

For the experienced admin, this statement can be followed: A server’s root certificate must be converted to ‘DER encoded binary X.509’ format.

Step 1: Obtain the root (not intermediate) certificate for the server in base64 format. This should look something like this:

-----BEGIN CERTIFICATE-----

VQQGEwJaQTEiMCAGA1UECBMZRk9SIFRFU1RJTkcgUF

VSUE9TRVMgT05MWTEdMBsGRVNUMRwwGgYDVQQDExNU

aGF3dGUgVGVzdCBDQSBSb290MB4XDTA1MTEwNzExMj

...removed lines....

BgEFBQcBAQQmMCQwIgYIKwYBBQUHMAGGFmh0dHA6Ly

FLgsY+QtxYo=

-----END CERTIFICATE-----

Step 2: Cut and paste this into notepad and save (or rename) this file with “.cer” extension, i.e.

Step 3: On a Windows PC (XP is used here), double-click the file you created. A Certificate application will start after several seconds. There are three tabs (General, Details, and Certification Path). Select the ‘Details’ tab.

Now press ‘Copy to File…’ button to start the ‘Certificate Export Wizard’. Press ‘Next’. Now select ‘DER encoded binary X.509 (.CER)’ and press ‘Next’. Continue to save the file with any name like . Make sure the filename has a ‘.cer’ extension.

Step 4: Get this file to the device via any means (email, Bluetooth, memory card, etc.). Find the file on the device and select it. If these steps were followed correctly, the device will start to import the certificate. Follow prompts and when asked, check
the boxes for both ‘Internet’ and ‘Online cert. checking’.

Result: You should see a new certificate installed in the device’s Security management list.

Otherwise, the phone will display an error about file format not being supported. If this happens, the certificate has not been imported.
