Application.MAC.Tunenup removal instructions

What is Application.MAC.Tunenup?

Application.MAC.Tunenup 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.

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 Application.MAC.Tunenup 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.

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 Application.MAC.Tunenup 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.
