How to uninstall Disk Tuner from the operating system

What is Disk Tuner?

The Disk Tuner app scans Mac computers for duplicate files, junk files, installed software, and offers removal of unwanted items to free up disk space. In fact, developers might distribute this app using dubious methods, thereby increasing the chance that some users could download and install it inadvertently.

Apps that people download and install unintentionally are classified as potentially unwanted applications (PUAs).

Some PUAs scan computers for unwanted items (software, files), errors, malware, etc., but generate fake scan results and state that they will not remove any "detected items" unless users pay for activation. In this way, people are tricked into purchasing bogus software. It is not known for certain whether Disk Tuner has this behavior, however, there is a strong possibility.

Note that this app might also be distributed with a browser hijacker, adware-type app, or another PUA.

Adware-type apps generate ads (for example, coupons, banners, surveys, and pop-ups) that often promote dubious sites or even download and install unwanted apps by running certain scripts.

Browser hijackers modify browser settings (such as the default search engine, homepage, and new tab) to promote a fake search engine. Browser hijackers prevent removal of the fake search engine address from the browser settings until the app that promotes it is no longer installed..

More examples of potentially unwanted applications are MacFly Pro, MacClean360 and AweCleaner. Typically, these apps are not malicious, however, they are commonly monetized by offering use of their full (paid) versions.

As mentioned, these apps can generate fake results and are useless - they do not remove/fix any genuine issues.

How did potentially unwanted applications install on my computer?

PUAs are distributed via download/installation set-ups of other products. This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling".

Rushing download/installation processes (e.g. ignoring terms, skipping steps and settings, etc.) increases the risk of inadvertently allowing bundled content into the system.

Some PUAs have "official" download sites. Intrusive advertisements proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs without users' consent.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided.

When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on.

Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others). If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately.

Installed programs must be activated and updated with tools or implemented functions that are provided by the official developers. No other third party, unofficial tools should be used.

Note that it is illegal to activate licensed software with ‘cracking’ tools. Files and programs should be downloaded from official websites and via direct download links. Avoid third party installers and the tools/sources mentioned above.

Do not open website links or files in irrelevant emails that are received from unknown, suspicious addresses. These bogus emails are often disguised as official and important. Regularly, scan your computer with reputable, up-to-date antivirus or anti-spyware software.

If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
