How to remove "Smart Mac Booster" from Mac?

What is "Smart Mac Booster"?

Smart Mac Booster is very similar to many other apps of this type, such as Auto Mac Booster, Auto Mac Speedup, and Speedup Mac Pro. This app supposedly operates as an optimization tool allowing users to find and fix various errors, clean Mac computers from unnecessary data, and improve MacOS operating system performance. In fact, Smart Mac Booster is categorized as a potentially unwanted application (PUA) and is promoted using a deceptive (dubious) website and the "bundling" method. Thus, in many cases, people download and install this app unintentionally.

Smart Mac Booster scam

When launched, Smart Mac Booster allows users to run a scan, which then finds various issues that can supposedly only be fixed if this app is activated (i.e. the software is purchased). The free version is capable only of running a scan. In fact, purchasing this app does not necessarily mean that it will be capable of removing or fixing detected issues. PUAs that are promoted through dubious websites and using the "bundling" method cannot be trusted. They often run fake scans that detect so-called 'issues' that do not exist. PUA developers design them in this way to trick people into paying for their apps. It is not certain whether Smart Mac Booster is one of these rogue apps, however, most apps promoted using the aforementioned channels are untrustworthy. The website promoting Smart Mac Booster displays fake virus alerts/notifications. These websites should never be trusted. Additionally, apps promoted using the "bundling" method are often installed together with other unwanted apps such as browser hijackers, adware-type apps, and so on. If installed, PUAs of this type feed users with intrusive ads, cause unwanted redirects to untrustworthy websites, and collect user-system information. We recommend that you uninstall Smart Mac Booster and check for unwanted apps installed on the default browser (extensions, plug-ins, or add-ons). Removed any dubious entries.

There are many potentially unwanted apps on the internet, some of which might have different behavior. They are presented as legitimate and useful, however, most are designed only to generate revenue for the developers. They provide none of the features or tools promised .

How did potentially unwanted applications install on my computer?

An official website can be used to download Smart Mac Booster and there at least one other deceptive website which displays a fake virus alert and runs a fake virus scan. This leads to another website from which it can also be downloaded. In any case, using these websites requires intentional download of Smart Mac Booster. Most people install these apps unintentionally when they click intrusive ads or developers use "bundling", a deceptive marketing method used to trick people into downloading and installing unwanted apps with other software that they intentionally download and install. To trick them, developers hide PUAs in "Custom", "Advanced" and other similar settings of software download or installation set-ups and hope that people will go through these processes without checking the available settings. In summary, unwanted downloads and installations usually happen when people click dubious (intrusive) ads and download/install software without changing setup options.

How to avoid installation of potentially unwanted applications?

Download all software using official websites (sources that can be trusted) and direct links. Do not use tools such as torrent clients, eMule and other Peer-to-Peer networks, unofficial (dubious) websites, third party downloaders (and installers), and other sources of this kind. All downloads and installations should be handled with care. Check all included settings (such as "Advanced", "Custom", and so on) and deselect offers to install/download unwanted software. Intrusive ads may seem legitimate, however, they cannot be trusted, especially those displayed on dubious websites. When clicked, they can open deceptive, potentially malicious websites such as gambling, adult dating, pornography, etc. If you experience these random redirects or suspicious, intrusive ads, it is possible that there a potentially unwanted app is installed on the browser or operating system. Check the list of installed browser apps (extensions, plug-ins, add-ons) and remove unwanted, suspicious apps immediately. Also check for unwanted programs installed on the MacOS operating system and uninstall them. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
