How to remove "yourfine4updatesset[.]best" from Mac?

What is "yourfine4updatesset[.]best"?

Yourfine4updatesset[.]best is a scam website, which operates by alerting users that the Adobe Flash Player is allegedly outdated and requires to be updated. The updater yourfine4updatesset[.]best offers is illegitimate. At the time of research, it installed Mac Cleanup Pro PUA (Potentially Unwanted Application), instead of the promised updates. Usually, content endorsed and/or proliferated via such deceptive sites - is fraudulent and nonoperational. It is expressly advised against trusting yourfine4updatesset[.]best and webpages similar to it. These pages are rarely entered intentionally, most visitors to them get redirected by intrusive adverts or by PUAs, already preset on the system.

yourfine4updatesset[.]best scam

Yourfine4updatesset[.]best has several appearance variations, however their purpose is the same. This webpage displays pop-up windows, which are very similar to ones detailed in the "Fake Software Update POP-UP" article. The first window yourfine4updatesset[.]best shows urges visitors to update to the latest version of Flash Player, as the current version is outdated. When this pop-up is closed, the site displays several more. The second one repeats the alert and states that Flash cannot be used, if an update from Adobe is not downloaded. The top-right and bottom-right are rephrased repetitions of the same message, with the bottom one adding that users need the update "in order to continue watching". The background page details that Adobe Flash Player is an essential plug-in, enabling users to view content ranging from video to animations, as well as for online gaming. It also informs, that due to the Flash Playing being outdated it lacks the latest security updates and has been blocked (i.e. is currently nonoperational). To rectify this, users are told to download an updated version. Clicking any of the proffered buttons, leads to the download of a fraudulent Adobe Flash Player, which appears highly legitimate. However, installing it will not update said product and allow unwanted or potentially malicious content to the system. As mentioned, at the time of research it spread Mac Cleanup Pro in this manner. Software of this type is not uncommon, e.g. Advanced Mac BoosterQuick Mac CareMacCleansePro are a few fake MacOS (Mac Operating System) cleaners/optimizers. Typically, these applications require activation to become operational. In other words, they need to be purchased to work, despite being bought - they usually remain nonoperational.

Fake software updaters/installers, like the one endorsed by yourfine4updatesset[.]best, frequently contain more than one PUA (e.g. adware or browser hijackers). These apps rarely look dubious and proclaim to possess various "useful" features. Rarely do these features work as advertised, and more often than not - are utterly nonfunctional. That is because the only purpose of unwanted applications is to generate revenue for their developers. PUAs are designed to cause redirects to untrustworthy, deceptive/scam and even malicious websites. Some types run intrusive advertisement campaigns; deliver undesirable and harmful ads. Said adverts not only diminish browsing quality, but also carry certain risks. Other types make unauthorized changes to browsers (hijack them) and promote fake search engines. It is not uncommon for PUAs to have data tracking abilities. These monitor browsing activity (browsing and search engine histories) and collect users' personal information (IP addresses, geolocations and personal details). This private data is then passed onto third parties (potentially, cyber criminals), intent on misusing it for financial gain. To summarize, PUAs can cause browser/system infiltrations and infections, as well as lead to financial losses, severe privacy issues and even identity theft. To ensure device and user safety - all suspicious applications and browser extensions/plug-ins should be removed without delay.

There are thousands of deceptive/scam webpages on the Internet. They typically use a variety of scare-tactics, to trick users into downloading/installing/purchasing untrustworthy software and/or have other heinous purposes. These sites can warn users that an important application is outdated/at risk or that there are threats/issues on the device, and similar. Users should note that no website can detect viruses, malware, etc. present on systems. Apple.com-mac-optimization.live, apple.com-mac-optimizer.live, trksmm, badmonday are a few examples of other scam pages.

How did potentially unwanted applications install on my computer?

PUAs mainly spread through download/installation setups of other products. This false marketing method of pre-packing ordinary software with unwanted or malicious content is called "bundling". Fake updaters are another source of such undesirables. Rushed download/installation processes (e.g. ignored terms, used pre-set options, skipped steps, etc.) - increase the risk of potential system infiltrations and infections. Some PUAs have "official" download sites. When clicked, intrusive advertisements can execute scripts to stealthily download/install these apps, as well.

How to avoid installation of potentially unwanted applications?

It is recommended to research content, before downloading/installing it. Only official and verified download channels should be used. Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), free file-hosting websites, third party downloaders and similar sources are deemed to be untrustworthy; therefore advised against use. Download/Installation processes should be approached with caution. That includes reading terms, exploring all available options, using the "Custom/Advanced" settings to decline additional apps, functions, tools, etc. Intrusive ads usually appear legitimate and innocuous, but they redirect to highly questionable webpages (e.g. pornography, adult-dating, gambling and others). Should users encounter advertisements/redirects of this kind - they are to inspect the device 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.
