I keep getting this security warning message:
Warning. The authenticity of this content cannot be
verified, therefore it cannot be trusted.

The test root has not been enabled as a trusted root.

Do you want to install Popup killer no more popups....

I'm going crazy, this message is popping up ALL THE TIME
now. I have even tried downloading the popup killer that
the message is advertising just to see if the message
would stop, but it doesn't. How do I get this to stop?
