If you are reading this page (and you didn't have to click through a certificate warning to do it), then your computer likely has the GoAgent root CA certificate installed. You should remove it because while you have it installed, anyone may sign certificates and impersonate any web site towards you.
The certificate you want to remove has the fingerprints
SHA1 Fingerprint=AB:70:2C:DF:18:EB:E8:B4:38:C5:28:69:CD:4A:5D:EF:48:B4:0E:33 MD5 Fingerprint=56:B1:20:86:1B:0A:B0:61:38:00:1B:C3:67:CF:0C:CC
In Firefox, open the preferences, then go to Advanced, Certificates, View Certificates, Authorities, and select “GoAgent CA” in the list. Click the “Delete or Distrust...” button, then click OK.
On Ubuntu, delete the file
/usr/local/share/ca-certificates/GoAgent.crt and run the
command
update-ca-certificates --fresh
On Windows, refer to these instructions. Follow the instructions under “Adding certificates to the Trusted Root Certification Authorities store for a local computer”, but at step 8, right-click on “GoAgent CA” and select “Delete”.
On Mac OS X, open the application called Keychain Access. Click the lock to unlock it and enter your password. In the side panel, select “System” and “Certificates”. Highlight “GoAgent CA” and press the delete key on the keyboard. Click the “Delete” button and enter your password again.
