How to remove apps downloaded from Nonamenba websites on Mac computers

What is "Nonamenba"?

Nonamenba is a scam website group designed to promote dubious software. This variant endorses the Smart Mac Booster Potentially Unwanted Application (PUA). Users, who access these sites are presented with alarms about an alleged threat present on their device. For removal of this fake virus, Nonamenba offers Smart Mac Booster. Note that no web page can detect threats/issues present on the system, and any claims to this effect cannot be trusted. Furthermore, apps promoted by these sites are often rogue and nonfunctional. Deceptive/scam sites are commonly opened via redirects caused by intrusive advertisements or PUAs already infiltrated into the device.

Nonamenba scam

Visitors to Nonamenba first see a pop-up window, which claims that a website visited earlier has infected the MacOS (Mac Operating System) with a virus. Closing this window reveals a different web page, which repeats the initial claim. It also adds that a full system scan is required to find and eliminate dangerous files/applications. To give the impression of legitimacy, Nonamenba lists the visitor's 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, attempting this redirects users to the promotional web page of Smart Mac Booster. Downloading this app in fact downloads the maccleaner.pkg file, which is a known to spread various PUAs. As well as being an unwanted application, Smart Mac Booster is rogue software. Like many other fake Mac cleaners/optimizers (e.g. MacCleansePro, K9-MacOptimizer, Qbit Mac Optimizer, etc.), it requires activation to become operational. Even after activation by making a purchase, however, it remains nonoperational.

PUAs often seem legitimate. They lure users into downloading/installing with offers of a wide variety of "useful" functions. Despite how good these offers may sound, the advertised features are rarely operational. The sole purpose of all unwanted applications is to generate revenue for the developers, and they have many dangerous capabilities to achieve this. PUAs can cause redirects to sale-based, untrustworthy, deceptive/scam and malicious websites. They also run intrusive advertisement campaigns. The ads they deliver severely diminish the browsing experience and carry certain risks due to the harmful sites they redirect to, and for their ability to stealthily download/install unwanted content. Some apps within 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 infiltration/infections, and lead to financial loss, serious privacy issues, even identity theft. To ensure device and user safety, all suspicious applications and browser extensions/plug-ins must be removed immediately.

NonamebnmSmmhckNothsws, and Badmonday are a few examples of scam page families identical to Nonamenba. Scams of this kind often use scare tactics to urge visitors into downloading/installing/purchasing the content they endorse. This manifests as various alarms, alerts and warnings of detected threats/issues, or of an outdated piece of crucial software. The sites then advertise software/updates, which will allegedly rid users of these fake problems.

How did potentially unwanted applications install on my computer?

Some PUAs (such as Smart Mac Booster) have "official" promotional websites, from which they can be downloaded/purchased, however, these apps can also be downloaded/installed together with other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious content is called "bundling". Rushing download/installation processes (e.g. ignoring terms, skipping steps, etc.) increases the risk of unintentionally allowing bundled applications onto systems. Another source of PUAs are intrusive advertisements. When clicked, these can execute scripts to make rogue downloads/installations.

How to avoid installation of potentially unwanted applications

Research all content, before downloading/installing. Use only official and verified download channels, as opposed to P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), free file-hosting sites, or other unofficial/third party downloaders. Treat download and installation processes with caution. Read the terms, explore all available options, use the "Custom/Advanced" settings, and opt-out of additional apps, tools, functions, etc. Intrusive ads typically seem normal and harmless, however, they redirect to dubious web pages (e.g. pornography, gambling, adult-dating and others). If you experience these ads/redirects, 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.
