How to remove Update_3239 from browsers and operating systems

What is Update_3239?

Update_3239 is adware that is designed to serve advertisements, change certain browser settings (to promote a fake search engine), and collect sensitive information. In this way, Update_3239 functions as adware and a browser hijacker.

Users do not generally download or install these apps intentionally and, for this reason, Update_3239 is categorized as a potentially unwanted application (PUA). Developers distribute this app with another PUA called OriginalEngineSearch, which is distributed via a fake installer for Adobe Flash Player.

Like most apps of this type, Update_3239 serves advertisements (e.g., banners, coupons, surveys, and pop-up). Usually adware-type applications serve advertisements that promote/open dubious websites or even cause unwanted downloads and installations.

Update_3239 also changes browser settings such as the address of the default search engine, homepage, and new tab to the address of a fake search engine. Frequently, users cannot remove the address that was assigned by the browser hijacker from settings unless they first uninstall the rogue app.

Note that Update_3239 can also track and collect information such as passwords, telephone numbers, credit card details and various other sensitive details. This information could be misused to steal personal accounts and identities, and to make fraudulent purchases and transactions.

It could also be sold to third parties (potentially, cyber criminals) and misused for other malicious purposes.

How did Update_3239 install on my computer?

One of the most popular ways to distribute/promote PUAs is to include them into download/installation set-ups as 'additional offers'. This distribution method is called "bundling".

Typically, users can decline offers to download and/or install included apps via "Advanced", "Custom" or other settings of the set-ups (or by unticking available checkboxes), however, many users fail to do this. By leaving the aforementioned settings unchanged, they inadvertently download and install PUAs with regular programs.

In this case, users are tricked into installing Update_3239 when they use a fake installer for Adobe Flash Player, which is used to distribute Update_3239 and the OriginalEngineSearch app. Additionally, unwanted downloads and/or installations can be caused by clicking deceptive advertisements that execute certain scripts.

Note that, in most cases, these ads appear on dubious web pages.

How to avoid installation of potentially unwanted applications

You are advised to download files and programs from official websites and via direct download links. Other tools and sources such as third party downloaders and installers, unofficial pages, and Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used to download or install software.

Check all "Custom", "Advanced" and other similar settings (or available checkboxes) for offers to download and/or install unwanted apps. Do not click ads on dubious websites, since they can be designed to open bogus web pages or cause unwanted downloads and installations.

Remove any unwanted, suspicious extensions, plug-ins and add-ons installed on the browser, and software of this kind from the operating system. If your computer is already infected with Update_3239, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
