It might be worth running these additional steps from the Malwarebytes site (these are for a specific hijacker but they work for all malware). Page down once and you'll see the links to the 5 steps which run different programs. Just work through them one by one. It uses AdwCleaner, Junkware Removal Tool, Malwarebytes Anti-Malware Free and HitmanPro (you can use the last just as a one off, so there's no need to install it). The 5th and last step shows how to reset various mainstream browsers to recommended settings easily since some malware can alter this.
In fact I'd recommend everybody to run the first 4 steps as a minimum monthly, it certainly won't hurt.
