What is "Fake flash player update"?

There are many websites that are designed to deceive visitors into using a fake Adobe Flash Player installer, which supposedly updates the currently installed version. These fake installers are designed to install browser hijackers, adware and other potentially unwanted applications (PUAs). In some cases, they infect operating systems with ransomware, Trojans, or other high-risk malware. Typically, these fake Adobe Flash Player installers are promoted on untrustworthy web pages that have nothing to do with the official Adobe Flash Player version or its download page. Criminals who promote such scams also target Mac users.

Fake flash player update scam

At the time of research, a deceptive page promoting a fake Adobe Flash Player installer suggested that the installed version of Adobe Flash Player might be out of date and recommended an update. These sites often claim that the installed version is out of date and will not work unless it is updated. In any case, fake Adobe Flash Player installers do not update the Adobe Flash Player - they install PUAs such as a browser hijackers or adware-type apps. Typically, browser hijackers promote fake search engines (by changing certain browser settings) and gather information. In most cases, they collect browsing-related data, however, they might also record personal information. Developers misuse the data to generate revenue by selling it to third parties (potentially, cyber criminals), who then misuse it in other ways. Adware is software that serves various intrusive advertisements. For example, coupons, banners, surveys, and pop-ups. These open untrusted pages or download/install unwanted apps by executing certain scripts. Note that adware-type apps can also track information. As mentioned, fake Adobe Flash Player installers can be designed to install ransomware, Trojans or other malicious software. Ransomware is malware that encrypts files so that they cannot be recovered without tools held only by the cyber criminals who designed the program. This software can cause data and financial loss. Trojans are malicious programs that often proliferate and install other software of this kind, including ransomware. Therefore, unofficial, deceptive pages that offer to update Adobe Flash Player can never be trusted.

Generally, people do not intentionally visit deceptive web pages suggesting that Adobe Flash Player is out of date - these pages are opened through clicked deceptive advertisements, other untrusted sites or by installed PUAs. If a browser opens dubious pages automatically, a PUA is likely to already be installed.

How did potentially unwanted applications install on my computer?

PUAs are often downloaded and installed through the set-ups of other software. I.e., when they are included into download and installation set-ups as "additional offers". These can usually be found in "Custom", "Advanced", or "Manual" settings. When people download and install programs without checking and changing these settings, they allow PUAs to be downloaded and installed by default. This PUA distribution method is known as "bundling". Unwanted downloads and installations can also be caused by clicking deceptive advertisements that run certain scripts.

How to avoid installation of potentially unwanted applications

Third party downloaders, installers, Peer-to-Peer networks (e.g, torrent clients, eMule), unofficial pages, and other similar download, installation tools, channels are often used to distribute PUAs. Therefore, software and files should be downloaded only from official websites and through direct links. Downloads and installations should not be performed without first checking "Advanced", "Custom" and other settings. These commonly mention offers to download and install additional, unwanted software. Do not click advertisements that are displayed on dubious websites. When clicked, these ads can open untrusted websites or cause unwanted downloads/installations. Remove any unwanted, suspicious extensions, add-ons, plug-ins installed on the browser immediately. Also remove software of this kind that is installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
