How to remove EngineFiles from your browser and operating system

Also Known As: Ads by EngineFiles
Type: Mac Virus
Damage level: Medium

What is EngineFiles?

EngineFiles is an app designed to improve the browsing experience, however, it is categorized as a potentially unwanted application (PUA) and adware-type software. When installed, EngineFiles forces browsers to display various ads. It is also likely to gather browsing data and other information. People often download and install software such as EngineFiles unintentionally.

EngineFiles adware

In most cases, applications such as EngineFiles serve intrusive content (advertisements) in the form of coupons, banners, surveys, pop-ups, and so on. People who click these ads are usually redirected to various untrustworthy web pages.

Adware-type apps sometimes display ads that, if clicked, execute scripts designed to download and/or install unwanted, potentially malicious software. Furthermore, EngineFiles might display ads and also collect data relating to users' browsing habits.

For example, IP addresses, geolocations, entered search queries, addresses of visited websites. In some cases, these apps collect personal, sensitive details. The developers misuse gathered data to generate revenue, or sell it to third parties (potentially, cyber criminals) who misuse it for the same purpose.

People who have adware installed on their browsers and/or operating systems risk becoming victims of identity theft, experiencing problems relating to browsing safety, online privacy, and other issues. To avoid this, do not trust PUAs and remove any installed adware immediately.

More examples of apps that are very similar to EngineFiles include CentralLocator, AreaProduct, and CentralHere. In most cases, they are advertised as legitimate and useful apps, however, few deliver any useful features or other value. Typically, they are designed only to display ads and gather information.

As mentioned, people do not generally download or install these apps intentionally.

How did EngineFiles install on my computer?

People often inadvertently download and/or install unwanted apps when they click deceptive ads or when software developers distribute them using a marketing method called "bundling". They use this method to trick people into downloading and installing potentially unwanted apps together with other software.

I.e., they include PUAs into the download/installation set-ups of other (usually free) programs and do not disclose related information properly. Typically, offers to download and/or install PUAs can be found in "Advanced", "Custom" and other similar settings of the set-ups.

Many people leave these settings unchecked and unchanged, thereby allowing unwanted apps to be downloaded and/or installed with regular software.

How to avoid installation of potentially unwanted applications

Download software from official websites. Avoid other tools such as third party downloaders (and installers), torrent clients, eMule (and other Peer-to-Peer networks), unofficial pages, and so on. Check settings such as "Advanced", "Custom" of the download/installation set-ups and dismiss any offers to download or install unwanted software.

Do not trust ads displayed on dubious web pages. If clicked, they often redirect people to other untrustworthy websites. Clicking them might also lead to download/installation of unwanted apps on the browser or computer.

Remove any unwanted, unknown plug-ins, add-ons or extensions installed on the web browser, and programs of this type from the operating system immediately. If your computer is already infected with EngineFiles, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
