How to remove MacBooster from your computer
Written by Tomas Meskauskas on (updated)
What kind of application is MacBooster?
The MacBooster (MacBooster 6 and MacBooster 7) application claims to provide various system optimization tools. Many users believe that MacBooster is legitimate and useful, however, developers proliferate this app using the "bundling" method. Therefore, it often infiltrates systems without permission and is categorized as unwanted application.
More about MacBooster
As mentioned above, MacBooster infiltrates systems without permission. Therefore, although MacBooster claims to enhance overall system performance by cleaning junk files, removing viruses, and so on, its presence might affect performance. Note that MacBooster can infiltrate systems that are optimized and virus-free.
It runs in the background, uses system resources, and occupies memory, thereby affecting system performance. Although this app is technically legitimate, in many cases it is categorized as an unwanted application. Therefore, you might want to consider removing it.
In most cases, criminals "bundle" several rogue applications at once, and so there is a high probability that MacBooster was delivered with adware or browser-hijacking apps. These programs deliver intrusive advertisements, cause unwanted redirects, and gather sensitive information.
This poses a direct threat to your privacy and Internet browsing safety and they should be eliminated immediately.

Conclusion
Dozens of potentially unwanted applications (such as UnzipPro, MyShopcoupon, and Any Search Manager) infiltrate systems without users' permission. Unlike MacBooster, however, most are not legitimate. By offering many "useful features", unwanted apps attempt to give the impression of legitimacy, and yet their only purpose is to generate revenue for the developers.
Rather than giving any real value for regular users, potentially unwanted applications deliver intrusive advertisements, gather sensitive information, cause unwanted redirects, and promote in-app purchases.
How did unwanted programs install on my computer?
As mentioned, developers promote MacBooster using a deceptive marketing method called "bundling" - stealth installation of third party applications together with regular software/apps. Developers do not adequately disclose installation of potentially unwanted applications.
Therefore, they "bundle" unwanted apps within "Custom/Advanced" settings (or other sections) of the download/installation processes. Furthermore, many users are likely to rush these procedures and skip steps - behavior that often leads to inadvertent installation of unwanted apps. In this way, users expose their systems to risk of various infections and compromise their privacy.
How to avoid installation of unwanted applications?
As well as using the "bundling" method, criminals proliferate potentially unwanted applications via intrusive advertisements (which redirect to malicious websites and execute scripts that download/install malware or unwanted apps). To prevent this situation, be very cautious when downloading/installing software, and browsing the Internet.
Carefully analyze each window of the download/installation dialogs and opt-out of all additionally-included programs. We advise you to download your programs from official sources only, using direct download links. Third party download/installation tools are monetized using the "bundling" method, and thus these tools should never be used.
Intrusive ads typically seem legitimate, however, they redirect to gambling, adult dating, pornography, and other dubious sites. They are often delivered by adware-type apps. Therefore, if you experience suspicious redirects, remove all dubious applications and browser plug-ins.
The main reasons for computer infections are poor knowledge and careless behavior - caution is the key to safety. If your computer is already infected with unwanted apps, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.

Frequently Asked Questions (FAQ)
What is the purpose of an unwanted application?
Undesirable applications are specifically engineered with the primary goal of generating revenue through multiple methods. They achieve this by promoting in-app purchases to users, enticing them to spend money on virtual goods, features, or services within the app. Additionally, these applications often employ aggressive strategies by delivering intrusive and disruptive advertisements, which can significantly disrupt the user experience.
Is MacBooster unwanted application legal?
In the majority of cases, unwanted applications are legally permissible because they typically include End User License Agreements (EULAs) that explicitly inform users about the potential behaviors of the application. These EULAs serve as a form of disclosure, outlining the app's intended functionalities and any associated risks, thus allowing users to decide whether to proceed with the installation.
Is having MacBooster installed on my computer dangerous?
MacBooster is not a malicious application. However, it may be distributed alongside unwanted apps like browser hijackers, advertising-supported apps, and similar undesirable programs.
Will Combo Cleaner help me remove MacBooster unwanted application?
Combo Cleaner will conduct a thorough computer scan to remove all undesirable and potentially harmful applications. It is important to recognize that relying solely on manual removal may not yield a flawless solution, as remnants of files could persist within the system, even if the primary software has been uninstalled.
