How to remove Update_3239 from Mac?
What is Update_3239?
Update_3239 is the name of adware that is designed not only to serve advertisements but also to change certain browser settings (to promote a fake search engine) and collect sensitive information. Simply said, Update_3239 functions not only as adware but also as a browser hijacker. As a rule, users do download and install apps of this type knowingly. For this reason Update_3239 is categorized as potentially unwanted application (PUA). It is known that its developers distribute alongside with another PUA called OriginalEngineSearch which is distributed via a fake installer for Adobe Flash Player.
Like most apps of this type, Update_3239 is designed to serve advertisements (e.g., banners, coupons, surveys, pop-up ads). Usually adware-type applications serve advertisements that are designed to promote/open questionable websites and/or even cause unwanted downloads, installations. Also, Update_3239 changes browser settings such as the address of a default search engine, homepage and new tan to an address of some fake search engine. Most of the times users cannot remove the address that was assigned by a browser hijacker from browser settings unless they uninstall that app. One more important reason not to have Update_3239 installed on a browser and/or computer is because it can collect information such as passwords, telephone numbers, credit card details and some other sensitive information. Such information could be misused to steal personal accounts, identities, make fraudulent purchases, transactions, it could be sold to third parties (potentially cyber criminals) and/or 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 in various download and/or installation setups 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 setups (or by unticking available checkboxes). However, not all users do that. When they leave the aforementioned settings unchanged, they download and/or install PUAs alongside with programs that they download and/or install intentionally. In this particular case users get tricked into installing Update_3239 when they use a fake installer for Adobe Flash Player which is used to distribute not only Update_3239 but also the OriginalEngineSearch app. Additionally, unwanted downloads and/or installations can be caused by clicking deceptive advertisements that are designed to execute certain scripts. It is worthwhile to mention that in most cases such ads appear on questionable pages.
How to avoid installation of potentially unwanted applications?
Programs, files should be downloaded from official pages and via direct links. Other sources, tools like Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial sites, third party downloaders, etc., can be used as tools to promote/distribute potentially unwanted, or even malicious apps. Download and/or installation setups that have "Custom", "Advanced" (or other) settings should be analyzed - it is common that they are used to distribute unwanted apps. Simply said, it is recommended to check setups for offers to download and/or install unwanted apps before finishing download and/or installation processes. Additionally, it is advised not to trust (click) advertisements that are displayed on questionable websites, more often than not those ads are designed to open other shady pages. In some cases they can be designed to cause unwanted downloads and/or installations by running certain scripts. Any suspicious, unwanted apps (add-ons, extensions, plug-ins) that are installed on a browser should be eliminated. Programs of this kind that are installed on a computer should be removed too. 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.
