How to remove apps downloaded from "Latest version of Adobe Flash Player" scam pages on Mac computers

What is "Latest version of Adobe Flash Player"?

Displayed by various scam websites, "Latest version of Adobe Flash Player" is a deceptive message employed to trick visitors into using a fake Adobe Flash Player installer, which actually installs a potentially unwanted application (PUA) such as, for example, a browser hijacker or adware-type app. These fake installers are commonly designed to install multiple PUAs. In some cases, they install malicious software including ransomware, Trojans, or other high-risk malware. In any case, never download or install software or files from these websites. Browsers usually open websites of this type due to PUAs that are already installed.

Latest version of Adobe Flash Player scam

When opened, websites of this type display a pop-up window claiming that Adobe Flash Player is out of date and encouraging visitors to update it. The other pop-up windows states that Adobe Flash Player is out of date, but also does not include the latest security updates and cannot be used (until visitors download and install an updated version). Typically, these scam pages download a file called "AdobeFlashPlayerInstaller.dmg". This filename name might vary. Note that files downloaded from these pages do not install any new/legitimate versions of Adobe Flash Player - they simply install browser hijackers, adware or multiple PUAs. Typically, browser hijackers promote fake search engines by changing certain setting and collecting browsing related data such as geolocations, entered search queries, addresses of visited websites, IP addresses and other details. In some cases, PUAs can access and record personal information. Adware commonly tracks information and feeds users with intrusive ads, usually in the form of coupons, banners, pop-ups, surveys, and so on. People who click these ads are redirected to dubious web pages or cause download/installation of unwanted, potentially malicious software. Fake Adobe Flash Player installers can cause installation of ransomware - software that encrypts data. Typically, victims cannot use their files unless they pay a ransom to cyber criminals. Furthermore, rogue installers can infect systems with Trojans - these programs often install other malware, thereby causing chain infections. In summary, no software should be downloaded or installed through these scam websites.

Other examples of similar pages include streamoverlyquickprogram[.]com, reliableultimatesafevideoplayers[.]info and biggerupdateforvideos[.]best. All suggest that there is a new version of Adobe Flash Player available and encourage visitors to download it from them. In fact, none download a legitimate Adobe Flash Player installer - they download a fake installer that installs unwanted, potentially malicious software. As mentioned, these scam websites are usually opened by PUAs that are installed on the browser and/or operating system.

How did potentially unwanted applications install on my computer?

In most cases PUAs are downloaded and installed when people intentionally (or unintentionally) click deceptive advertisements or download/install programs without changing settings that are available in the set-ups. Typically, developers distribute PUAs using a deceptive marketing method called "bundling". I.e., they include PUAs into various download/installation set-ups and present them as additional offers. Typically, these offers can be found in "Advanced", "Custom", and other settings of the set-ups. Unfortunately, many people leave these unchanged, thereby agreeing by default with offers to download or install additional (unwanted) applications. Clicking ads can cause download/installation of PUAs, since some ads execute rogue scripts (note that they cannot do this without being clicked).

How to avoid installation of potentially unwanted applications

Software should be downloaded from official websites and using direct download links. Third party downloaders, installers, unofficial websites, Peer-to-Peer networks (e.g., torrent clients, eMule), and other such tools/channels should not be trusted - they are often monetized by promoting various unwanted applications. Furthermore, unwanted downloads and installations can be prevented by declining offers to download or install unwanted apps (these are often listed in "Custom", "Advanced" and other settings included in the set-ups). Do not click intrusive ads, especially if shown on dubious web pages - they can redirect people to untrusted web pages or download/install unwanted software. If the browser opens dubious web pages or displays unwanted ads, we recommend that you remove all suspicious, unwanted extensions, plug-ins and add-ons immediately. Also remove programs of this kind from the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
