For the last week, I am getting the error msg pop up below whenever I open PostBox mail reader.  Doesn't appear to affect anything - just annoying.  Plus I worry that it might be some type of malware.

I am running Windows 7 Home.


Thanks for any help.  




This is the error msg pop up:


Server connection failed

stats.g.doubleclick.net:443 uses an invalid security certificate

The certificate is not trusted because the issuer certificate is not trusted

(Error code: sec_error_untrusted_issuer)

This could be a problem with the server's' configuration or it could be someone trying to impersonate the server.

If you have connected to this server successfully in the past the error may be temporary and you can try again later.

This issue isn't indicative of malware. What it means is that the website or server is not authenticating properly with it's SSL certificate or has an invalid certificate.


What this means for you is that you cannot trust the connection. You should not use it for sensitive information or banking of any form.


Here is more info on SSL certificates.
