FWIW I have used the free version of Malwarebytes for years and it is my go-to program to keep my Mac malware free. I have no hesitation suggesting it to anyone to scan their HD and get rid of malware.
Chances are really good if you open Safari and quickly clear history, cookies etc, that will rid your computer of that Malware. Also check your personal account in system prefs. to be sure there are no unwanted log in items.
