How to remove redirects to check-apple-for-cleaning sites from Mac computers

What is Check-apple-for-cleaning?

Check-apple-for-cleaning is a group of deceptive websites promoting various scams and, by extension, dubious content. Redirecting to other rogue sites is also common behavior to websites owned by the check-apple-for-cleaning group. They have been observed running "Adobe Flash Player is outdated" scams, which operate by claiming that Flash Player is out of date and offering bogus updates. Fake updaters are often used to infiltrate untrusted software (e.g. adware, browser hijackers, etc.) into systems and infect them with malware (e.g. ransomware, trojans, etc.). Typically, users access these sites via redirects caused by intrusive advertisements or Potentially Unwanted Applications (PUAs) already installed on the device.

Check-apple-for-cleaning scam

PUAs typically seem legitimate and offer various "useful" functions, which are mostly nonoperational. By posing as genuine software, they can infiltrate devices. They also have various other distribution methods such as being disguised as software updaters, or packed with them - this is just one PUA promotional technique. As well as causing redirects to deceptive/scam, sale-oriented, untrusted, rogue, compromised and malicious websites, the unwanted applications have dangerous capabilities. Adware-type PUAs run intrusive ad campaigns. The delivered ads (e.g. pop-ups, banners, surveys, coupons, etc.) significantly diminish the browsing experience by reducing browsing speed and limiting web page visibility, however, they are far more than just a nuisance. When intrusive advertisements are clicked, they can redirect to dubious and dangerous websites, and also execute scripts to stealthily download/install unwanted content (including PUAs). Other PUAs called browser hijackers modify browser settings, restrict or deny access to settings, and promote fake search engines. Regardless of their type, most PUAs can track data. They can record browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information derived from it (IP addresses, geolocations and personal details). This sensitive data is often shared with third parties (potentially, cyber criminals) seeking to misuse it for profit. To summarize, PUAs can cause browser and system infiltration/infections, lead to serious privacy issues, financial loss and even identity theft. Therefore, to ensure device integrity and user safety, you are strongly advised to remove all suspicious applications and browser extensions/plug-ins immediately upon detection. Additionally, all software must be updated with tools/functions provided by legitimate developers.

worldofcontenting.infotherightwaytofindplayering.pro, and bestevervideoplayers.info are some examples of websites similar to those owned by the check-apple-for-cleaning group. There are countless deceptive websites on the internet. Popular scam models include (but are not limited to) alerts that an essential piece of software is outdated/missing, warnings that the system is infected or at risk, prize giveaways, "amazing offers" and so on. The only purpose of these scams is to generate revenue for their designers at users' expense. This goal is achieved by tricking users into downloading/installing and purchasing nonoperational, untrusted or malicious content, calling fake and expensive technical support/service lines, revealing personal information (e.g. communication/social and banking account credentials, credit card details, etc.), making monetary transactions (e.g. fake fees and payments), amongst many other tactics.

How did potentially unwanted applications install on my computer?

PUAs proliferate through the download/installation set-ups of other software. This deceptive marketing technique of packing regular products with unwanted or malicious additions is called "bundling". Rushing download and installation processes (e.g. ignoring or skimming terms, skipping steps and sections, using pre-set options, etc.) endangers devices with potential infiltration and infections originating from bundled content. Some PUAs have "official" download websites, which are often promoted by other deceptive/scam sites. When clicked, intrusive ads can execute scripts to download/install PUAs without users' permission.

How to avoid installation of potentially unwanted applications

It is important to research products to verify their legitimacy, before download/installation or purchase. Use only official and verified download channels. Untrustworthy download sources such as Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule, etc.), free file-hosting websites and other third party downloaders can offer deceptive and bundled content. When downloading/installing, you are advised to read the terms, study all available options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, etc. Software should be updated using tools/functions from genuine developers, as third party updaters are high risk. Intrusive ads tend to seem normal and harmless, however, they can redirect to dubious pages (e.g. gambling, adult-dating, pornography and others). If you encounter these advertisements/redirects, inspect the system and immediately remove all suspicious applications and browsing 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.
