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.
