How to uninstall EssentialModule from a computer

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

What kind of application is EssentialModule?

While surfing deceptive pages, we discovered an application called EssentialModule. Our team tested this app and found that it displays annoying advertisements. Thus, we classified EssentialModule as adware. It is worth mentioning that users do not normally download and install adware knowingly.

EssentialModule adware

EssentialModule adware in detail

EssentialModule shows advertisements that can open websites designed to extract sensitive information, distribute questionable or malicious software, lure visitors into calling fake technical support numbers, etc. Also, those ads can cause unexpected downloads and installations.

Another reason not to trust EssentialModule is that it may be tracking users. We inspected many apps like EssentialModule and found that they often can read sensitive information such as credit card details, passwords, and other personal data. Their developers can misuse obtained data to hijack online accounts, steal money, make fraudulent purchases, steal identities, etc.

Also, adware can hijack a web browser. In such cases, adware changes the web browser's settings (default search engine, homepage, and new tab page) to promote shady search engines and (or) other untrustworthy websites.

Adware in general

The purpose of advertising-supported software is to display intrusive advertisements (often to promote shady websites and apps). Also, it can function as a browser hijacker and track users/collect various data. A big part of adware is promoted and distributed using questionable and often deceptive methods.

More adware examples are ModuleUpgrade, GeneralOperation, and ConnectedField.

How did EssentialModule install on my computer?

Apps like EssentialModule are often distributed via fake installers (e.g., deceptive installers mimicking Adobe Flash Player installers). These installers are promoted on deceptive pages suggesting that some software is outdated, installation of an application is required to perform certain actions, etc.

Also, users install adware via deceptive advertisements and alongside other software (when adware is bundled with other software). Installers containing adware usually have "Advanced", "Custom", or other settings. Adware gets installed after finishing installations without changing those settings (or unticking checkboxes).

How to avoid installation of unwanted applications?

Download applications from legitimate (official) websites and stores. It is not safe to use P2P networks, third-party downloaders, stores, unofficial websites, etc., to download apps and files. Also, check downloaders and installers for unwanted apps and deselect them using the provided settings before downloading and installing programs.

Do not trust advertisements on dubious pages (e.g., torrent sites, illegal movie streaming pages) or agree to receive notifications from such sites. If your computer is already infected with EssentialModule, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
