Thornz,
In addition to using ADWCleaner and Malwarebytes Anti-Malware, you may also want to consider resetting whichever browsers you use. :)
Whatever you do, please do not call the number on any of those warnings!!!
What browsers do you use?
I use Google Chrome (For almost everything I do). If there is nothing I can do on it, I use Mozilla Firefox.
