How to remove "Nothsws" from Mac computers

What is "Nothsws"?

Nothsws is a family of scam websites, which are designed to promote dubious software. They operate by warning users of a supposed 'threat' detected on their devices and recommending Smart Mac Booster for its removal. No web page can find threats/issues on systems. Therefore, the problems they claim to find are false and any apps they endorse are often bogus and nonoperational. Victims rarely access Nothsws websites intentionally - most are redirected by Potentially Unwanted Applications (PUAs) already present on their devices.

Nothsws scam

Nothsws first displays a pop-up window. The message within it informs users that a site they visited earlier has infected their MacOS (Mac Operating System). Clicking "OK" will allegedly begin the removal process. Once this window is closed, Nothsws shows a different web page reiterating the alert and urging users to perform a full system scan, which will apparently locate and remove harmful apps/files. It also lists the visitor's Mac details, such as device brand, OS version, browser, IP address, Internet provider and location. Once the instructions have been followed, a fake system scan is initiated. This "detects" the "Bankworm" virus, and Nothsws then requests users to download Advanced Mac Cleaner for elimination of it from the MacOS. The "REMOVE VIRUS NOW" button redirects to the promotional web page of Smart Mac Booster. The download process of this application leads to the maccleaner.pkg file, which is typically used to spread PUAs. You are strongly advised against installing this file. Due to its questionable proliferation methods, Smart Mac Booster is classified as a PUA. There are many bogus apps similar to Smart Mac Booster including, for example, MacCleansePro, K9-MacOptimizer, Mac Space Reviver, etc. They usually need to be purchased to become active and perform their advertised functions. Even after activation, however, they often remain nonoperational.

Most PUAs share common traits. They often seem legitimate and lure users to install with offers of "useful" and "beneficial" features. These features are rarely operational. Even if they do work, it is not as promised. The only purpose of unwanted applications is to generate revenue for the developers - they have no genuine value to regular users. PUAs cause redirects to untrustworthy and malicious sites. They can also deliver intrusive advertisements and hijack browsers. PUAs often have data tracking capabilities. They record users' browsing activity (browsing and search engine histories) and collect personal information (IP addresses, geolocations and other details). This gathered data is then shared with third parties (potentially, cyber criminals) seeking to misuse it for financial gain. In summary, PUAs can lead to browser and system infiltration/infections and to serious privacy issues, financial loss and even identity theft. Therefore, remove all dubious applications and browser extensions/plug-ins immediately upon detection.

The internet is rife with deceptive web pages. For example, Zxcvc, Vnbue, and Sundayfunny are all scam site families identical to Nothsws. They tend to use scare tactics to trick visitors into downloading/installing and/or purchasing their promoted software. They warn users of supposed threats/issues present on the device and offer untrustworthy applications to deal with the "detected" problems. Most users enter these websites unintentionally - they are redirected by intrusive advertisements or PUAs.

How did potentially unwanted applications install on my computer?

PUAs often proliferate via the download/install set-ups of other products. This deceptive marketing technique of packing normal software with unwanted and/or malicious content is called "bundling". Rushing download/installation processes (e.g. ignoring terms, using pre-set options, skipping steps and sections, etc.) increases the risk of allowing bundled software onto devices. Some PUAs, such as Smart Mac Booster, also have "official" download web pages. Intrusive ads also proliferate these apps. Once clicked, they stealthily download/install PUAs.

How to avoid installation of potentially unwanted applications

Research all content, before downloading/installing. Use only official and verified download sources. Avoid Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), free file-hosting sites, third party downloaders and similar - they are untrusted. Treat download/Installation processes with caution. Read the terms, explore all available options, use the "Custom/Advanced" settings, and decline offers to download/install supplementary apps, tools, features, etc. Intrusive advertisements typically seem legitimate and harmless, however, when clicked, they can redirect to dubious web pages (e.g. gambling, pornography, adult-dating and others). If you experience these ads/redirects, inspect the system and remove all suspect 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.
