Qbit Mac Speedup Unwanted Application (Mac)

Also Known As: Qbit Mac Speedup potentially unwanted application
Type: Mac Virus
Damage level: Medium

What is "Qbit Mac Speedup"?

Qbit Mac Speedup is promoted as an optimization tool for Mac computers that fixes various errors, cleans MacOS systems, and makes them run faster. Note, however, that developers promote this app by bundling it into set-ups of other software. People often install these apps unintentionally and, therefore, Qbit Mac Speedup is categorized as a potentially unwanted application (PUA).

Qbit Mac Speedup scam

After completing the system scan, Qbit Mac Speedup displays a list of various 'problems' that should be fixed to make the computer run smoothly and without errors. To successfully fix these detected issues, clean files, or do anything else, users are encouraged to activate this app by purchasing it.

Note that apps promoted though set-ups of other software often provide fake results and are used to trick people into believing that there are many issues with their computers, and that they should solve them by purchasing software.

It is unknown whether Qbit Mac Speedup is a legitimate app (and generates legitimate results), however, as mentioned, most apps promoted using this method are bogus. Furthermore, apps that are included into other download/installation set-ups often come together with browser hijackers, adware-type, and other PUAs.

Generally, they serve users with various ads and gather browsing-related information. They display ads that conceal underlying content of visited pages. These are usually coupons, pop-up ads, surveys, banners, and so on. If clicked, they might run scripts designed to download and install potentially malicious apps or simply open other untrustworthy websites.

PUAs also gather data relating to users' browsing habits. For example, IP addresses, entered search queries, URLs of visited websites, geolocations, and so on. PUA developers share the information with third parties who might be cyber criminals. Other parties misuse the data to generate revenue.

If there are any PUAs installed on your system, remove them immediately. The same applies to Qbit Mac Speedup. Do not use apps that are promoted using deceptive methods.

Cleanup My Mac, Smart Mac Booster, and Auto Mac Booster are just some apps similar to Qbit Mac Speedup and many others of this type. PUAs are commonly presented as useful and legitimate tools, however, do not trust apps that are distributed using deceptive methods, since many deliver no useful features or functionality.

How did potentially unwanted applications install on my computer?

In most cases, people download and install unwanted apps when they click intrusive advertisements or install (mostly free) software. Developers use a deceptive marketing method called "bundling" and hide PUAs in the "Custom", "Advanced" settings or options of regular software setups.

PUA developers are aware that many users often skip installation steps without checking available settings. Skipped download/installation steps or clicked intrusive ads are the main reasons for unintentional download/installation of potentially unwanted applications.

How to avoid installation of potentially unwanted applications?

To remain safe, browse the internet and download and install software with care. Do not download apps from unofficial/untrustworthy websites, using torrents, eMule or other Peer-to-Peer networks, or other similar sources/tools. Remember to check all available "Custom", "Advanced" and other similar options of software download or installation setups.

If clicked, intrusive advertisements displayed on dubious pages usually lead to other untrustworthy, potentially malicious websites. Do not click them or trust pages that are opened by them. If you experience unwanted redirects or ads regularly, check all extensions, add-ons, and plug-ins that are installed on your browser, and uninstall all suspicious/unwanted entries.

Also ensure that there are no programs of this type installed on your computer. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
