How to uninstall Quick Mac Booster PUA

What is "Quick Mac Booster"?

Quick Mac Booster is rogue software, endorsed as a tool capable of improving system performance and speed.

Amongst its advertised functionality are detection and elimination of various unwanted files (e.g. unused, duplicate, large, temporary, junk, etc.), application management and system startup time improvement, however, due to the dubious methods used to proliferate this app, Quick Mac Booster is classified as a Potentially Unwanted Application (PUA).

Software within this classification is often deceptive and untrusted.

While dubious distribution techniques are commonly used for legitimate products, they are mostly employed to proliferate rogue or bogus content. Despite appearing normal and useful, PUAs are seldom legitimate.

For example, fake system cleaner/optimizer-type PUAs often require activation (i.e. purchase) to perform their advertised function, however, even after activation, these unwanted applications often remain nonoperational. This is also the case with Quick Mac Booster.

Furthermore, PUAs have additional unwanted capabilities. They can force-open untrusted/rogue, compromised, deceptive, scam and malicious sites. Adware-types can run intrusive advertisement campaigns.

The ads they deliver diminish the browsing experience - when clicked, the advertisements redirect to dubious/malicious websites and some can even stealthily download/install rogue software (e.g. PUAs). Browser hijacking PUAs modify browser settings to promote fake search engines.

Therefore, with a browser hijacker installed, each new browser tab/window opened and each search query typed into the URL bar redirects to the promoted address. Rogue search engines are typically unable to provide unique results, and so they redirect to Google, Yahoo, Bing and other legitimate search engines.

Browser hijackers can reset any changes users try to make to their browsers and/or restrict/deny access to the browser settings. Most PUAs (regardless of their type) can track data. They can record browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather personal information extracted from it (IP addresses, geolocations and other details).

This vulnerable data is usually shared with third parties (potentially, cyber criminals) intent on misusing it for financial gain. To summarize, the presence of unwanted apps on devices can lead to system infections, financial loss, serious privacy issues and even identity theft.

To ensure device and user safety, remove all suspicious applications and browser extensions/plug-ins immediately upon detection.

iMacCleaner, Easy Mac Care, MacReviver and MacRepair are some examples of PUAs similar to Quick Mac Booster. These unwanted applications often tempt users into download/installation with a wide variety of "useful" functionality. The features promised can range from system cleaners/optimizers to easy access tools for online content.

Despite how good these offers may sound, the advertised functions usually do not work, even after the software is purchased. The only purpose of PUAs is to generate revenue for the developers. These apps deliver intrusive ad campaigns, cause redirects, hijack browsers and track private data.

How did potentially unwanted applications install on my computer?

Some PUAs (including Quick Mac Booster) have official promotional web pages from which they can be downloaded. These applications can also be downloaded/installed with other products. This deceptive marketing method of packing regular software with unwanted or malicious additions is called "bundling".

Rushing download/installation processes (e.g. ignoring terms, using pre-set options, etc.) increases the risk of unintentionally allowing deceptive and/or bundled content onto systems. Intrusive ads can infiltrate these apps into systems as well. Once clicked, they can execute scripts to download/install PUAs without users' permission.

How to avoid installation of potentially unwanted applications

All products must be researched to verify their legitimacy, prior to download/installation and/or purchase. Use official and trustworthy download channels. Dubious download sources such as unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders commonly offer deceptive and/or bundled content.

When downloading/installing, it is important to read the terms, study all available options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive advertisements may seem normal and harmless, however, they can redirect to dubious pages (e.g. gambling, pornography, adult-dating and others).

If you encounter these ads/redirects, inspect the system and remove all suspect applications and browser extensions/plug-ins without delay. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
