If CCleaner doesn't do it, then get the free Revo Uninstaller (great software) and uninstall everything through Revo, and in the last window, uninstall only the dark links.
Reboot (very important).
Then download the free version (I'd do it through Impulse) and install it. Then you'll have to reboot.
Make sure your A/V and firewall are off when doing this (download through Impulse).
Should work.
