Learn how to remove fake Adobe Flash Player update virus from Mac and thereby prevent the browser from being redirected to rogue software installation websites.

  1. Update Flash Plugin For Mac

Update: November 2019

The Adobe Flash Player update virus is one of the common ways cybercriminals try to deposit additional harmful code onto a Mac. It usually operates in tandem with such threats as bogus system utilities that report non-existent problems and thus attempt to manipulate users into activating the licensed copy of the scareware. This type of a ruse can be used to promote such unwanted apps as Mac Auto Fixer or Mac Cleanup Pro. Both will run phony scans of the host system and claim to detect hundreds of issues – ones that aren’t there for real. The targeted Mac users therefore deal with a double contamination scenario, where they first encounter recurrent and really annoying instances of browser rerouting and then suffer the consequences of counterfeit software activity. It’s the early stage of the brainwashing that is backed by the Adobe Flash Player update virus popups.

The reason why the architects of this trickery have added the Flash Player to the mix of their shenanigans is probably because it’s a commonly used program trusted by most users. The caveat is that a completely different piece of code is camouflaged as the explicitly stated software. This part of the incursion is usually isolated to the web browser, although there are rare cases where the misguiding popups appear when the browser is closed. The virus manifests itself through random redirects to a site that instantly displays a popup alert saying, “Adobe Flash Player is out of date”. Meanwhile, a prompt at the top of the page layout may wrongfully emphasize that “Latest version of Adobe Flash Player is required to encode and/or decode (Play) audio files in high quality”. Everybody likes quality multimedia content, so a lot of users end up falling for this trick.

In all of these adverse situations, those who pay attention to detail will notice that there is something wrong with such a recommendation. First off, the URL of the website that generates these Adobe Flash Player update popups is a giveaway. Obviously, it has nothing to do with the genuine vendor, being clearly designed to mimic the legit update workflow. Furthermore, despite the fact that the alerts may provide a button to opt out, such as “Later” or “Cancel”, clicking it isn’t likely to close the dialogs for more than a few milliseconds. The pre-configured website script will relaunch the ads, so the victims may have to force quit Safari, Chrome, Firefox – or whatever browser is infected – to get the bogus notifications out of the way.

Adobe® Flash® Player is a lightweight browser plug-in and rich Internet application runtime that delivers consistent and engaging user experiences, stunning audio/video playback, and exciting gameplay. Installed on more than 1.3 billion systems, Flash Player is the standard for delivering high-impact, rich Web content.

A whole new attack mechanism with the fake Adobe Flash Player update popups at its core is distributing an emerging Mac threat codenamed Tarmac. Also known as OSX/Tarmac, this infection relies on another type of harmful code called OSX/Shlayer. The latter is a notorious Mac Trojan whose objective is to set large-scale malvertising schemes in motion. Its original entry point is a phony alert about an out-of-date version of the Flash Player. Once inside, it reaches out to the Command and Control server and downloads a copy of Tarmac onto the host. The second-stage malware is code signed and leverages RSA encryption to camouflage the fishy gist of its payload, which allows the pest to fly below the radar of quarantine-aware software running on the Mac. As soon as OSX/Tarmac is launched, it attempts to elevate its privileges on the machine by generating a dialog that says, “Play wants to make changes”.

This popup asks for the administrator’s username and password, making it look like the request comes from Adobe Flash Player. Even if the victim is prudent enough to refrain from entering the credentials, Tarmac continues to run with fairly high permissions. Just like Shlayer, it can easily connect to its C&C server and download arbitrary code from it, such as rogue system utilities, adware, or even Mac ransomware. This recently discovered tandem of dangerous programs relying on counterfeit Flash Player update ads demonstrates that the campaign is evolving and assuming more unsettling characteristics.

This troublemaking scenario tends to be bolstered by a malicious browser plugin or extension. The fake helper object modifies Internet settings, such as the homepage or search defaults, and may even interfere with the DNS server preset. This is what causes the redirects in the first place. What happens if you click “OK” and actually download the pseudo Adobe Flash Player update is a whole new attack layer. The affiliated harmful program will establish persistence on the Mac by adding itself to Login Items and utilizing antivirus evasion mechanisms. Then, it will start launching scans of the macOS, purporting to find numerous memory issues and security problems each time. Again, this routine is aimed at pressuring the victim into making a hasty decision to pay for the cyber-impostor’s licensed version. So much for the tactic. Speaking of the fix for the Adobe Flash Player update virus activity, the only method is to spot the components of the pest on the Mac and remove them. See below to learn how it’s done.

Whereas Adobe Flash Player is useful software that enhances your online experience in plenty of ways, it can as well be a source of vulnerabilities exposing your Mac to cyber-attacks. Furthermore, many users simply don’t catch up with the frequent patches rolled out by the publisher, inadvertently turning their computers into low-hanging fruit.

It comes as no surprise that many users end up disabling the Flash plugin in their web browser at some point. This tool can be safely turned off at the browser level without the need to uninstall it from a Mac altogether. Here is how to disable it in popular browsers:

  • In Safari menu bar, select Preferences
  • Select the Security tab, spot the Internet Plug-ins area, and click Plug-in Settings
  • Remove the checkmark next to Adobe Flash Player in the subsequent screen
  • Click Done
Google Chrome:
  • Type chrome://settings/content in Chrome’s URL bar
  • Scroll down and find the Flash entry on the page. Click it
  • Spot the Allow sites to run Flash option and toggle it off using the adjacent slider
Mozilla Firefox:
  • Type about:addons in the URL bar and hit Enter
  • Select Plugins in the left-hand navigation bar
  • Find the Flash Player plugin and expand the appropriate menu
  • Choose between Ask to Activate and Never Activate options. The latter is preferable if you don’t want to see annoying popup dialogs during web surfing.

In case the regular Flash Player update popups are interrupting your activities, there is a way to get them out of sight. Be advised that by clicking the Remind Me Later button on these notifications you simply postpone the process, and the irritating message will reappear in an hour. Here’s how to prevent these messages from appearing on your Mac for good:

  • Go to the Finder and select System Preferences
  • Click the Flash Player icon
  • When on the Flash Player screen, hit the Updates tab in its upper part
  • You will see the following options to choose from: Allow Adobe to install updates, Notify me to install updates, and Never check for updates
  • Enable a radio button next to the Never check for updates option. You can alternatively allow Adobe to install updates – in that case, Flash Player will be updated on its own without producing any popups

If a malicious app is already on board your system, then a macOS update isn’t likely to fix the problem. That being said, updating your Mac does address known security vulnerabilities so that you are protected against common exploits and mainstream viruses further on. Another benefit of applying the updates as soon as they are available is that your Mac will be optimized to ensure smooth performance. Keep in mind that human error might undermine the built-in Mac defenses no matter how top-notch they are.

No, you can’t – as long as you diligently keep Flash Player up to date and all the new versions are installed from the official source. In a vast majority of incidents where this utility is exploited to deposit malware onto Macs, the victims neglect the update hygiene and use very old versions of the product with multiple unpatched security loopholes in them.

Flash updates pushed via popup alerts on rogue websites are a completely different story. The installation clients in this case include bundled malware. If you happen to opt for this kind of an offer, a contamination is pretty much inevitable. The article above highlights the common infection scenarios through fake Adobe Flash Player update notifications. Note that Mac users are typically redirected to these landing pages because their browsers have been hijacked. Therefore, removal of the underlying virus is a prerequisite of addressing the predicament.

Safari no longer supports most plug-ins. To load webpages more quickly, save energy, and strengthen security, Safari is optimized for content that uses the HTML5 web standard, which doesn't require a plug-in. To enhance and customize your browsing experience, you can use Safari Extensions instead.

If you visit one of the small number of webpages that still require a plug-in to show certain content, Safari might tell you that the plug-in is missing. And after you install the plug-in, Safari might ask how often you'd like to use it, or if you want to trust or update the plug-in.

Before you can use a plug-in that you've installed, you might need to turn it on:

  1. Choose Safari > Preferences from the Safari menu bar, then click Websites.
    In some earlier versions of Safari, click Security instead, then click Plug-in Settings.
  2. Select the plug-in from the list on the left, then use its checkbox to turn the plug-in on or off. After you turn on a plug-in, it remains active for as long as you regularly use that plug-in on any website.
  3. The pop-up menus on the right turn the plug-in on or off for specific websites. If you choose Ask, Safari will ask you for permission before allowing the website use the plug-in. The pop-up menu in the lower-right corner shows the default setting for when you visit other websites that require the plug-in.
