Every secure page comes up with an untrusted warning, how can I stop this?

Question

Every secure page I go to pops up with the untrusted warning. Even support.mozilla.com did it and amazon.com and facebook.com, etc. I add the exception and the very next time I go the page I get the same warning. It's getting rather silly. Half the time even after adding the exception half the page won't load, just the text.

There is no need to download anything to solve this problem. You may have installed a variant of the "VSearch" ad-injection malware.
Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination  command-C:
/Library/LaunchDaemons
In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
A folder named "LaunchDaemons" may open. Look inside it for a file with a name of the form
          com.something.daemon.plist
Here something is a variable word, which can be different in each case. It could be "cloud," "dot," "highway," "submarine," "trusteddownloads," or pretty much anything else.
There may also be a file named
           com.something.helper.plist
in the same folder.
If you find files with names that fit the above description, post what you have for "something."
