How to remove MacReviver from Mac computers

What is MacReviver?

MacReviver is advertised as software that helps Mac users to improve system performance and stability, however, various virus detection engines recognize its installer as that of a potentially unwanted application (PUA). Typically, apps of this type are distributed through the set-ups of other (usually free) programs and/or various deceptive websites. Therefore, people often download and install PUAs unintentionally, or they are deceived into it. In any case, apps categorized as PUAs should never be trusted.

MacReviver unwanted application

MacReviver allows users to scan systems for junk files, unwanted applications, remaining items owned by removed apps, redundant interface languages, cache, log files and other items, and to remove them. This software essentially cleans, optimizes and maintains Mac computers, and also restores performance and stability. Note that this software is not free. To use its features (remove 'detected issues') users must purchase it. PUAs tend to provide fake results and attempt to trick people into believing that there are many existing issues that, if fixed, would improve computer performance, stability, and so on. It is not known whether MacReviver is one of these applications, however, this is a strong possibility. PUAs are often installed through the set-ups of other programs - the set-ups are used to distribute multiple PUAs and various browser hijackers, adware, and other potentially unwanted apps are also installed. Browser hijacking apps promote fake search engines by changing certain browser settings and gathering various browsing-related information. Sometimes apps of this type target private, sensitive details as well. Adware feeds users with coupons, pop-ups, surveys, banners and other forms of ads. In most cases, these redirect people who click them to untrusted, potentially malicious pages, or they execute scripts designed to download and install PUAs. It is possible that the ads might cause installation of malicious programs. If apps of this type are installed on the browser and/or operating system, remove them immediately. Do not download or install any apps categorized as PUAs.

More examples of apps that are classified as PUAs include MacRepair, iWebPlayer and Total Mac Care. Most PUAs are advertised through deceptive websites (such as "Your Apple iPhone is severely damaged by (6) viruses!") or through the download/installation set-ups of other (mostly free) software. They are commonly advertised as legitimate, useful applications, however, many they are useless and deliver no real value.

How did potentially unwanted applications install on my computer?

People usually download and install unwanted apps when they are included into the download/installation set-ups of other software. This distribution method is known as "bundling". Typically, developers use it to trick people into downloading or installing PUAs together with regular software. Generally, offers to download or install PUAs can be found in settings such as "Custom" and " Advanced", however, many people fail to check and change them, thereby allowing bundled PUAs to be downloaded and installed with regular software. In some cases, unintentional downloads and installations are caused by clicking deceptive ads. If clicked, some ads execute scripts designed to download and install potentially unwanted, malicious apps.

How to avoid installation of potentially unwanted applications

Software and files should be downloaded only from official, trustworthy websites and via direct download links. Other sources and tools such as third party downloaders, installers, Peer-to-Peer networks (for example, torrent clients, eMule), unofficial pages, etc., should not be trusted. Unwanted downloads and installations can be prevented by checking settings such as "Custom", "Advanced" of the download/installation setup and declining offers to download or install additionally-included software (PUAs). Do not click intrusive advertisements, especially if they are shown on dubious websites - they often redirect to potentially malicious websites or cause download/installation of unwanted applications. Ads of this kind might also appear on legitimate sites. Remove any unwanted, suspicious extensions, plug-ins, and add-ons already installed on the browser, and programs of this type installed on the computer. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
