What is MAC.OSX.MacSweeper?
MAC.OSX.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.
The appearance of a fake Flash Player update setup that promotes a potentially unwanted application:
The most common form of potentially unwanted applications are disk cleaning apps. They stealthily install on computers, set themselves to start automatically on each system startup, and then perform ‘system scans’ that detect many issues that supposedly need addressing.
Appearance of potentially unwanted applications:
To fix the issues users are asked to pay for the license of the program. The main advice in such situation would be – don’t purchase a program that you didn’t install on your computer. People who distribute their software using deceptive methods shouldn’t be trusted with your banking details.
How did MAC.OSX.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.
How to avoid installation of MAC.OSX.MacSweeper in the future?
If you have accidentally installed a potentially unwanted application on your Mac, remove it immediately. To avoid these situations in the future, be cautious when browsing the Internet and especially vigilant when experiencing pop-up ads asking you to perform certain actions (such as downloading updates or security software). Download free software and software updates from developers’ websites only. Do not trust pop-ups that indicate virus infections. Do not download torrent files or software cracks. When installing free software, choose advanced or custom installation options – this will reveal any PUPs bundled with the installation.
