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

What is "yourfine4updatesset[.]best"?

yourfine4updatesset[.]best is a scam website, which operates by alerting users that the Adobe Flash Player is outdated and requires updating. The updater offered by yourfine4updatesset[.]best is bogus. At the time of research, it installed the Mac Cleanup Pro Potentially Unwanted Application (PUA), rather than the promised updates. Content endorsed and/or proliferated by these deceptive sites is often rogue and nonoperational. Therefore, do not trust yourfine4updatesset[.]best or similar sites. These web pages are rarely opened intentionally, since most visitors are redirected to them by intrusive ads or PUAs already present on the system.

yourfine4updatesset[.]best scam

yourfine4updatesset[.]best has several variations in terms of appearance, however, the purpose is the same. This webpage displays pop-up windows, which are very similar to those detailed in the "Fake Software Update POP-UP" article. The first window displayed by yourfine4updatesset[.]best urges visitors to update to the latest version of Flash Player, as the current version is apparently outdated. When this pop-up is closed, the site displays several more. The second repeats the alert and states that Flash cannot be used, unless an update from Adobe is downloaded. The top-right and bottom-right include duplicates of this message, with the bottom one adding that users need the update "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, and for online gaming. It also states that, due to Flash Player being outdated, it lacks the latest security updates and has been blocked (i.e., is currently nonoperational). To rectify this, users are instructed to download an updated version. Clicking any of the buttons leads to download of a fake Adobe Flash Player, which might seem legitimate, however, installing it will not update the product. In fact, it will allow unwanted or potentially malicious content to infiltrate the system. At the time of research, it spread Mac Cleanup Pro in this manner. Software of this type is common. For example, Advanced Mac BoosterQuick Mac Care, and MacCleansePro are just some examples of other fake MacOS (Mac Operating System) cleaners/optimizers. Typically, these applications require activation to become operational via a purchase. Despite any payments made, however, 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 often seem authentic and claim to possess various "useful" features. These features rarely work as advertised, and are mostly nonfunctional. The only purpose of these unwanted applications is to generate revenue for the developers. PUAs cause redirects to untrustworthy, deceptive/scam and even malicious websites. Some run intrusive advertisement campaigns - they deliver unwanted and harmful ads. The ads diminish the browsing experience and carry certain risks. Other types make unauthorized changes to browsers (hijacking them) and promote fake search engines. PUAs commonly have data tracking capabilities. They monitor browsing activity (browsing and search engine histories) and collect users' personal information (IP addresses, geolocations, and other details). This private data is then passed on to third parties (potentially, cyber criminals) intent on misusing it for financial gain. To summarize, PUAs cause browser/system infiltration and infections, and can lead to financial loss, serious privacy issues and even identity theft. To ensure device and user safety, remove all suspicious applications and browser extensions/plug-ins without delay.

There are thousands of deceptive/scam web pages on the internet. They typically use various scare tactics to trick users into downloading/installing/purchasing untrustworthy software, or they have other dangerous 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. Note that no website can detect viruses, malware, etc. present on systems. Some examples of other scam sites include Apple.com-mac-optimization.live, apple.com-mac-optimizer.live, trksmm, and badmonday.

How did potentially unwanted applications install on my computer?

PUAs mainly proliferate through the download/installation set-ups of other products. This deceptive marketing method of pre-packing normal software with unwanted or malicious content is called "bundling". Fake updaters are another source of PUAs. Rushing download/installation processes (e.g. ignoring terms, using pre-set options, skipping steps, etc.) increases the risk of potential system infiltration and infections. Some PUAs have "official" download sites. When clicked, intrusive advertisements can execute scripts to stealthily download/install these apps.

How to avoid installation of potentially unwanted applications

Research content, before downloading/installing. Use only official and verified download channels. Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), free file-hosting websites, third party downloaders and similar sources are untrusted and should be avoided. Download/Installation processes should be approached with caution. Read the terms, explore all available options, use the "Custom/Advanced" settings to decline additional apps, functions, tools, etc. Intrusive ads usually seem legitimate and innocuous, but they can redirect to highly dubious web pages (e.g. pornography, adult-dating, gambling and others). If you encounter these advertisements/redirects, inspect the device and immediately remove all suspicious 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.
