This procedure works as of now, as far as I know. Malware is always changing to get around the defenses against it. Some of the files listed may be absent in your case. To remove it, please take the steps below. You may have installed a fake 'utility' called 'Advanced Mac Cleaner.' Like any software that purports to automatically 'clean up' or 'speed up' a Mac, it's a scam, and some variants of it are ad-injection malware.
That's how you create problems, not how you solve them. First, never use any kind of 'anti-virus' or 'anti-malware' software on a Mac.
