If you know which app on your Mac is malicious, you’re half-way through the problem. First of all, you need to close the app and then root it out from the system processes.

Launch Agents and Daemons: Where else to look
So far we’ve covered browser Extensions, Applications, and Login Items trying to remove malware from your Mac. But these are not the only locations where malicious agents may be hiding. Another type of system services that could be affected by malware are the so-called Launch Agents and Daemons — yes, the name does derive from the word demon. These are small helper programs that stealthily run in the background, like software updaters or automatic backups.
While Launch Agents and Daemons are two different entities, both can be infiltrated by malware. As it often happens, trojan apps would place their executable files within the Launch Agents folder. The result — the virus app launches automatically and potentially harms or steals your data.
How to remove daemons and agents from the Mac’s startup
Click Finder
Choose Go > Go to Folder
Type in: /Library/LaunchDaemons
For Launch Agents, repeat the steps above, but this time search in 2 more locations:
/Library/LaunchAgents ~/Library/LaunchAgents
Inside you’ll find a bunch of PLIST files and if some of them look suspicious to you, delete them. Sure, the names of these files may not be very telling, but if you already know the problematic app that you are after, knowing this folder may help you fully extinguish it.

What is MAC.OSX.Adware.MacSweeper?
MAC.OSX.Adware.MacSweeper is the detection name for a potentially unwanted application (PUA) – software that infiltrates Mac systems without users’ consent. Many users report that, although they have not willingly installed new software, new applications appear on their computers. Unwanted applications also commonly infiltrate computers through fake downloads. For example, Mac users browsing the Internet might be confronted with a pop-up ad stating that Flash Player is out-of-date and requires updating. After users download and install Flash Player, they discover that a number of PUAs were also installed.
A term potentially unwanted application is used to describe a program that was installed on user’s Mac without a proper consent. While most of unwanted applications are not particularly dangerous, they can significantly slow down computer’s performance, show unwanted pop-up notifications and perform other unwanted behavior. The main objective of an unwanted application is to generate revenue for their developers, it’s most commonly done by showing intrusive advertisements or by asking a computer user to purchase a full version of the program.
Here’s a list of top 3 methods used in potentially unwanted applications distribution:
Software download portals: Many software download portals use ‘installers’ that bundle free software together with potentially unwanted applications. The safest sources from which to download applications are developers’ websites or the Mac App Store.
Fake software updates: Never trust a website that encourages you to update your Flash Player, Java, or other application. You should download updates from developers’ official websites only.
A Mac message states that a virus is found: No website is capable of determining if your Mac is infected. Do not trust any online pop-ups that inform you of computer infections – they are fake and their main purpose is potentially unwanted application distribution.
The appearance of a pop-up ad promoting installation of a fake Flash Player update:
Deceptive marketers devise various new methods to trick Mac users into installing software bundles. After infiltrating the system, PUAs might cause harm by tracking computer use and behavior. They can use utilize Mac resources by displaying advertisements and opening various pop-up windows. This reduces system performance.

How did MAC.OSX.Adware.MacSweeper install on my Mac?
The most common source of potentially unwanted applications are fake downloads. For example, fake Flash Player updates, java downloads, etc. Many software installers are also present within software ‘crack’ download and torrent websites. Deceptive marketers create various pop-up ads designed to trick Mac users into downloading legitimate software bundled with other potentially unwanted applications.
Appearance of a fake ‘virus found on your Mac’ pop-up:
Another common way to distribute potentially unwanted applications (often, disk cleaners and security-related applications) is through fake pop-up ads that indicate supposed computer infections. These unwanted ads claim to be legitimate Apple-related notifications and are designed to scare Mac users into downloading potentially unwanted applications onto their systems.
