How to remove apps downloaded from Nonamenba websites from Mac?

What is "Nonamenba"?

Nonamenba is the name of a scam website group, designed to promote dubious software. This variant endorses the Smart Mac Booster PUA (Potentially Unwanted Application). Users, who access these sites, are presented with alarms about an alleged threat on their device. For removal of this fake virus, Nonamenba offer Smart Mac Booster. It must be noted, that no webpage can detect threats/issues present on system; any that claim to so - cannot be trusted. Furthermore, apps pushed by them are often illegitimate and nonfunctional. Usually, deceptive/scam pages are accessed via redirects caused by intrusive advertisements or by PUAs, already infiltrated into the device.

Nonamenba scam

The first thing visitors to Nonamenba see is a pop-up window. It claims that a website visited today has infected the users' MacOS (Mac Operating System) with a virus. Closing this window reveals a different page, which repeats the initial claim. It also adds that a full system scan is required in order to find and eliminate dangerous files/applications. To complete the impression of legitimacy, Nonamenba lists visitors' device details (brand, OS version, browser, IP address, Internet provider and location). The "Scan Now" button starts a fake scan that "finds" a virus called "Bankworm". To remove this threat, the site recommends downloading Advanced Mac Cleaner. However, trying to do so redirects users to the promotional webpage of Smart Mac Booster. Downloading said app downloads the maccleaner.pkg file, which is a known spreader of various PUAs. Aside from being an unwanted application, Smart Mac Booster is a fraudulent piece of software as well. Like many other fake Mac cleaners/optimizers (e.g. MacCleansePro, K9-MacOptimizer, Qbit Mac Optimizer, etc.) - it requires activation to become operational; however, even after being purchased (i.e. activated) it remains nonoperational.

PUAs are designed to appear legitimate. They lure users into downloading/installing them with offers of a wide variety of "useful" functions. Despite how good these offers may sound, users should note that the advertised features are rarely operational. The sole purpose of all unwanted applications is to generate revenue for their developers and they have many heinous abilities to achieve this. PUAs can cause redirects to sale-based, untrustworthy, deceptive/scam and malicious websites. They run intrusive advertisement campaigns as well. The ads they deliver severely diminish browsing quality and carry certain risk themselves, due to the harmful sites they redirect to and for their ability to stealthily download/install undesirable content. Some apps under this classification can make unauthorized changes to browsers (hijack them) and promote fake search engines. Most PUAs can also track data, relating to browsing activity. Information of interest includes: browsing and search engine histories, IP addresses, geolocations and personal details. This sensitive data can then be shared with third parties and end up being used for criminal purposes. To summarize, PUAs can cause browser and system infiltrations/infections, and lead to financial losses, serious privacy issues, even identity theft. To ensure device and user safety, all suspicious applications and browser extensions/plug-ins must be removed immediately.

NonamebnmSmmhckNothswsBadmonday are a few examples of scam page families identical to Nonamenba. Scams of this kind usually use scare-tactics to push visitors into downloading/installing/purchasing content they endorse. This manifests as various alarms, alerts and warnings of detected threats/issues or of an outdated piece of crucial software. Then the sites advertise software/updates, which will allegedly rid users of the imaginary problems.

How did potentially unwanted applications install on my computer?

Some PUAs (like Smart Mac Booster) have "official" promotional websites, form which they can be downloaded/purchased. However, these apps can be downloaded/installed alongside other products. This false marketing technique of pre-packing regular software with unwanted or malicious content is called "bundling". Rushed download/installation processes (e.g. ignored terms, skipped steps, etc.) - increase the risk of unintentionally allowing bundled applications onto systems. Another source of PUAs are intrusive advertisements. When clicked, said ads can execute scripts to make such rogue downloads/installs.

How to avoid installation of potentially unwanted applications?

It is encouraged to always research content, before downloading/installing it. Only official and verified download channels should be used, as opposed to - P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), free file-hosting sites and other unofficial/third party downloaders. Download and installation processes should be treated with caution. Therefore, users should read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from additional apps, tools, functions, etc. Intrusive adverts typically look ordinary and harmless, however they redirect to unreliable webpages (e.g. pornography, gambling, adult-dating and others). Should users experience such ads/redirects, they are strongly advised to check the device and remove all dubious applications and/or 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.
