The instructions that I posted in this discussion a few months ago are now outdated. Since people are still finding the discussion, I'll post an update.
First, never use any kind of "anti-virus" or "anti-malware" software on a Mac. That's how you cause problems, not how you solve them. Don't follow the instructions of the scam developer, either.
It's likely that you will have installed other malware along with "Advanced Mac Cleaner." If you still have problems after removing it, I strongly suggest that you start your own discussion to address those problems.
To remove "Advanced Mac Cleaner," please take the steps below. Some of the files listed may be absent in your case. Back up all data before proceeding.
Malware is always changing to get around the defenses against it. This procedure works as of now, as far as I know. It may not work in the future. Anyone finding this comment a few days or more after it was posted should look for a more recent discussion, or start a new one.
If you paid for the software with a credit card, consider reporting the charge to the bank as fraudulent.
Step 1
Triple-click anywhere in the line below on this page to select it:
~/Library/LaunchAgents
Right-click or control-click the highlighted line and select
Services ▹ Open
from the contextual menu.* A folder named "LaunchAgents" may open. If it does, look inside it for files with a name that begins like this:
com.pcv.
Move any such file to the Trash.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.
Step 2
The malware is now permanently inactivated, provided that you don't reinstall it. This step is optional.
Delete the following items, if they exist, as in Step 1:
/Library/Application Support/amc
~/Library/AdvancedMacCleaner
There's no need to log out or restart after taking this step.
The problem may have started when you downloaded something, such as the application "FileZilla," from the "Sourceforge" website or some other Internet cesspit. Never visit that site again. All software should be downloaded only from the developer's website or from the Mac App Store, if applicable.
