How to remove "Quick Mac Fixer" from Mac computers

What is "Quick Mac Fixer"?

The Quick Mac Fixer application is supposedly capable of improving operating system performance. According to this software's promotional material, it can manage installed apps and remove unwanted files (e.g. unused, large, duplicate and junk files). Due to the dubious methods used to proliferate Quick Mac Fixer, it is classified as a Potentially Unwanted Application (PUA). Despite its legitimate appearance, software within the PUA category cannot perform the promised capabilities. Additionally, PUAs often have underlying dangerous functionality.

While dubious distribution techniques are used for normal products, they are more commonly employed to spread untrusted software. Some types of PUAs - fake system cleaners/optimizers - usually require activation to perform the advertised functionality. I.e., they must be purchased to work as promised. Following activation, however, they remain nonoperational - and this is likely to be the case with Quick Mac Fixer. Furthermore, PUAs can have additional features. They can force-open various dubious and malicious websites. Adware-types run intrusive advertisement campaigns. When clicked, they redirect to similarly harmful sites, and some can execute scripts to stealthily download/install rogue software (e.g. PUAs). Other PUAs called browser hijackers make alterations to browser settings to promote fake search engines. With this software installed, new browser tabs/windows opened and search queries typed into the URL bar redirect to the promoted address. Bogus search engines are seldom capable of providing search results, and so they redirect to Yahoo, Google, Bing and other genuine sites. Most PUAs (adware and browser hijackers) have data tracking capabilities. They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect sensitive information extracted from it (IP addresses, geolocations and other details). The gathered data typically contains personally identifiable information. Furthermore, PUA developers often monetize this information by sharing it with and/or selling it to third parties (potentially, cyber criminals). To summarize, the presence of unwanted apps on devices can lead to financial loss, system infections, serious privacy issues and even identity theft. To protect device integrity and user safety, you are strongly advised to eliminate all suspicious applications and browser extensions/plug-ins.

Total Mac CareQbit Mac Optimizer and Total Mac Fixer are some examples of unwanted apps similar to Quick Mac Fixer. PUAs usually offer "useful" functions, however, they are rarely operational and, even if they do work, it is not as promised. The only purpose of this unwanted software is to generate profit for the developers. Regular users receive no real value and can instead experience serious issues. PUAs deliver intrusive ad campaigns, cause redirects, hijack browsers and track private information.

How did potentially unwanted applications install on my computer?

Some PUAs (including Quick Mac Fixer) have "official" promotional web pages, from which they can be acquired. They can also be downloaded/installed together with products. This deceptive marketing tactic of packing regular software with unwanted or malicious additions is called "bundling". By rushing through download/installation processes (e.g. ignoring terms, skipping steps and sections, etc.), many users risk inadvertently allowing bundled content into the system. Intrusive ads 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

All products should be researched prior to download/installation. You are advised to download only from official and verified sources. Untrusted channels such as unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders can offer deceptive and/or bundled content, and should thus be avoided. When downloading/installing, it is important to read the terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out of supplementary apps, tools, features, and so on. Intrusive advertisements may seem legitimate and innocuous, however, they can redirect to dubious pages (e.g. pornography, gambling, adult-dating, etc.). If you encounter these ads/redirects, inspect the system and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
