Some recipients of my emails have been getting a bunch of code, letters and symbols, inserted into the email preceded by "span.IP". What is causing this and how can I fix it? Also (may be related) when i start up Thunderbird, I get the following error message:

Secure connection failed

live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because no issuer chain was provided. (Error code: sec_error_unknown_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.

Or you can add an exception…

What is the issuer for the cert you get?

more options

I really don't know enough about it to know who the issuer is. Can you direct me?

more options

In the 'Add Security Exception' dialog, there should be a button 'Details' or 'View Certificate' (something like that). It will show the details for the cert you received. Look for a field 'Issuer'.

This is what I see.

Not much to see there. Do you have something like BrowserSafe, Browser Safeguard, or Safeguard installed on your system?

more options

Yes. "BrowswerSafeguard with RocketTab" was installed on my computer on 4-3-2014. I don't believe that I intentionally installed this program. I'm not sure how it got there.

Browser Safeguard apparently attempts to intercept your secure connection to the server, so just uninstall it. Reboot your computer, and run a malware check.

It's also possible that it issued certificates for secure sites you visit. Those self signed certs could then be used by IE, so you should get rid of them as well.

In IE under Internet Options - Content tab click on Certificates. It opens to the Personal tab. Look for certificates issued by DO_NOT_TRUST_FiddlerRoot. Those are the ones created by Browser Safeguard.

Both, Thunderbird and Firefox use their own certificate store independent from the Windows certificate store. So they should not be affected by those certs.

For the future watch out for additional software being sneaked in when installing a program.
