How to remove "Securingchecknow" from Mac computers

What is "Securingchecknow"?

Securingchecknow is a family of scam websites promoting Mac Heal Pro and other similar applications using scare tactics. It alerts visitors of fake threats that it has supposedly detected and endorses the app for their removal. Do not trust these deceptive sites or download/install software they advertise. System cleaners and similar applications promoted by these websites are often fake and nonoperational, possibly even harmful. In most cases, users enter Securingchecknow sites due to having them force-opened by Potentially Unwanted Applications (PUAs) present on their devices.

Securingchecknow scam

Securingchecknow first displays a pop-up window, which claims that a trojan virus (e.tre456_worm_osx) was detected on the Mac OS. The background page lists the date and time when additional issues were detected. The site has allegedly found three viruses (two malware and one phishing/spyware infection) within the system. It urges users to take immediate action, as their system has been compromised. Additionally, it states that the visitor's data, personal, and banking information is at risk. Securingchecknow also shows a countdown timer, with time remaining until the damage becomes permanent. The bottom of the web page states that this site is purely advertorial. I.e., designed for advertising purposes and has no connection to Apple or Microsoft. After the "Scan Now" button is clicked, Securingchecknow initiates a fake system scan and lists various 'issues'. It states that the system is heavily damaged (at 33.2%) and there are three viruses present (Tapsnake, CronDNS, and Dubfishicv). Note, however, that Securingchecknow is a scam website - it has no scanning capabilities and all threats it finds are false. Clicking the "REMOVE VIRUSES NOW" button starts download of Mac Heal Pro. Software promoted on these web pages are PUAs and are unable to perform any of the advertised functions. They also require activation (via a purchase), however, despite payment made or activation, they often remain nonfunctional. Qbit Mac OptimizerMacEnizer, and K9-MacOptimizer are just some examples of unwanted applications similar to Mac Heal Pro.

In general, PUAs seem legitimate and often lure users to install by offering "useful" and "beneficial" features/capabilities, however, these functions rarely operate as promised and, in most cases, are nonoperational. The only purpose of all unwanted software/content is to generate revenue for the developers. Regular users receive no value. PUAs can cause redirects to sale-oriented, untrustworthy, compromised and even malicious websites. These apps also hijack browsers and can deliver intrusive advertisement campaigns (pop-ups, surveys, banners, coupons, etc.). Some have data tracking capabilities, which they use to monitor users' browsing activity (browsing and search engine histories) and gather their personal information (IP addresses, geolocations, and other details). This private data is then shared with third parties (potentially, cyber criminals) seeking to misuse it for financial gain. In summary, PUAs can cause browser and system infiltration/infections and lead to serious privacy issues, financial loss, and even identity theft. To ensure device and user safety, remove all dubious applications and browser extensions/plug-ins immediately.

Scam websites are common and most promote suspicious and/or fake applications. For instance, security5service.comprogressstream.com, and apple.com-guard-device.live are just some examples of similar web pages to Securingchecknow. They typically trick users into installing their fake apps by warning them of various 'threats' and 'issues'. While the products these sites offer may seem legitimate, it is unlikely that they are capable of operating as advertised (i.e., they have no scanning, virus removal, optimization, or other capabilities).

How did potentially unwanted applications install on my computer?

Some PUAs have "official" download websites, however, they can also be inadvertently installed together with other programs. This marketing method of pre-packing normal software with unwanted or malicious content is called "bundling". Rushing download/installation processes (e.g. ignored terms, skipping steps, using pre-set options, etc.) increases the risk of allowing deceptive or bundled software onto devices. Intrusive advertisements can also proliferate PUAs. Once clicked, they execute scripts to download/install PUAs without users' consent.

How to avoid installation of potentially unwanted applications

Research software and content to verify its legitimacy, before downloading/installing. Use only trustworthy and verified download channels. Peer-to-Peer sharing networks, unofficial and free file-hosting sites, third party downloaders and similar sources are untrusted and should not be used. Download and installation processes should be treated with caution. Read the terms, explore all possible options, use the "Custom/Advanced" settings, and opting-out of downloading/installing supplementary apps, tools, features, etc. Intrusive advertisements usually seem legitimate and harmless, however, they often redirect to dubious web pages (e.g. pornography, adult-dating, gambling, etc.). If you encounter these ads/redirects, inspect the system and immediately remove all suspect applications and/or browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
