How to remove "Quick Mac Fixer" from Mac?

What is "Quick Mac Fixer"?

Quick Mac Fixer is an application, supposedly capable of improving operating system performance. According to this software's promotional material, it can manage installed apps and remove undesirable files (e.g. unused, large, duplicate and junk files). Due to the dubious methods used to distribute Quick Mac Fixer, it is deemed to be a PUA (Potentially Unwanted Application). Typically, despite looking legitimate, software within the PUA category - cannot perform its promised abilities. Additionally, they can have unmentioned and heinous functionalities.

Quick Mac Fixer unwanted application

While questionable distribution techniques are used for ordinary products, it is more commonly employed to spread untrustworthy software. One type of PUAs - fake system cleaners/optimizers - usually require activation to perform the advertised functionalities. In other words, they must be purchased to work as promised. However, following activation, they remain nonoperational - and it is very likely to be the case with Quick Mac Fixer. Furthermore, PUAs can have additional features. They can force-open various unreliable and malicious websites. Adware-types run intrusive advertisement campaigns. Upon being clicked on, they redirect to similarly harmful sites and some can execute scripts to stealthily download/install software (e.g. PUAs). Other PUAs called browser hijackers make alterations to browser settings in order to promote fake search engines. With such a piece of software installed, new browser tabs/windows opened and every single search query typed into the URL bar - redirect to the promoted address. Illegitimate search engines are seldom capable of providing search results, so they redirect to Yahoo, Google, Bing and other genuine ones. Most PUAs (adwares and browser hijackers) have data tracking abilities. 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. What is more, PUA developers often monetize this information by sharing it with and/or selling it to third parties (potentially, cyber criminals). To summarize, 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, it is strongly advised to eliminate all suspicious applications and browser extensions/plug-ins.

Total Mac CareQbit Mac Optimizer and Total Mac Fixer are a few examples of unwanted apps akin to Quick Mac Fixer. All types of PUAs usually offer some sort of "useful" and "advantageous" functions. However, they are rarely operational and even if they do work - then, not as promised. The only purpose of unwanted software is to generate profit for the developers; to users - it has no real value and can instead cause various issues. PUAs are designed to deliver intrusive advert campaigns, cause redirects, hijack browsers and track private information.

How did potentially unwanted applications install on my computer?

Select PUAs (e.g. Quick Mac Fixer) have "official" promotional webpages, from which they can be acquired. They can also be downloaded/installed alongside other products. This false marketing tactic of packing regular software with unwanted or malicious additions - is called "bundling". By rushing through download/installation processes (e.g. by ignoring terms, skipping steps and sections, etc.) - users risk inadvertently allowing bundled content into the system. Intrusive adverts proliferate these applications as well. Once clicked on, they can execute scripts to download/install PUAs without user consent.

How to avoid installation of potentially unwanted applications?

All products should be researched prior to download/installation. It is recommended to only download from official and verified sources. Untrustworthy channels, like: unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders - often offer deceptive and/or bundled content; therefore, they are advised against use. When downloading/installing, it is important to read terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out from supplementary apps, tools, features, and so on. Intrusive advertisements tend to appear legitimate and innocuous, however they redirect to unreliable and questionable pages (e.g. pornography, gambling, adult-dating, etc.). In case of encounters with such ads/redirects, users must inspect the system and immediately remove all suspect applications and/or browser extensions/plug-ins from it. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
