You have some pretty dubious apps, including one ("HackStore") that seems to be a torrent client specifically for pirated software. I also notice that Microsoft Office is installed, but the activation daemon that goes along with it is missing. That would mean that Office couldn't run unless it had been hacked.
If you've been running pirated software downloaded from a torrent, you're an excellent candidate to be the first to install every new kind of malware that comes along. Within the scope of a Google search, no one else has ever reported an adware infection like the one you seem to have, not even on Windows.
Taking everything you say at face value, I almost have to suspect that you may have installed some kind of rootkit that modifies the operating system at a level that can't be detected by the means I use. Maybe it's causing the test script to give false results. That's always a theoretical possibility, though I've never actually seen it happen as far as I know. A rooted system can't be trusted to analyze itself.
If I'm right, then the only thing you can do is a full post-intrusion cleanup.
Back up all data to at least two different storage devices, if you haven't already done so. One backup is not enough to be safe. The backups can be made with Time Machine or with Disk Utility. Preferably both.
Erase and install OS X. This operation will destroy all data on the startup volume, so you had be better be sure of the backups. If you upgraded from an older version of OS X, you'll need the Apple ID and password that you used, so make a note of those before you begin.
When you restart, you'll be prompted to go through the initial setup process in Setup Assistant. That’s when you transfer the data from a backup.
Select only users and Computer & Network Settings in the Setup Assistant dialog—not Applications or Other files and folders. Don't transfer the Guest account, if it was enabled.
After that, check the App Store for software updates.
If the problem is resolved after the clean installation, reinstall third-party software selectively. I can only suggest general guidelines. Self-contained applications that install into the Applications folder by drag-and-drop or download from the App Store are usually safe. Anything that comes packaged as an installer or that prompts for an administrator password is suspect, and you must test thoroughly after reinstalling each such item to make sure you haven't restored the problem.
I strongly recommend that you never reinstall commercial "security" products or "utilities," nor any software that changes the user interface or the behavior of built-in applications such as Safari. If you do that, the problem is likely to recur.
Do not reinstall "AVG," any pirated commercial software such as Office, or anything at all that came from a torrent or from a third-world ISP.
Any system modifications that you do choose to install must be kept up to date. None is required for normal operation.
Before installing any software, ask yourself the question: "Am I sure I know how to uninstall this without having to wipe the volume again?" If the answer is "no," stop.
Never install any third-party software unless you know how to uninstall it.
That being done, change all Internet passwords and check all financial accounts for unauthorized transactions. Do this after the system has been secured, not before.
