How to remove DevModule from Mac?

What is DevModule?

This application is designed to function not only as adware but also as a browser hijacker and data collector. More precisely, it is designed to serve advertisements, promote a fake search engine (its address) and collect sensitive information. Most of the times users download and install apps like DevModule unknowingly, therefore, they are called potentially unwanted applications (PUAs).

DevModule adware

It is common that advertisements that are displayed by adware like DevModule are designed to promote (open) questionable websites or even cause downloads and/or installations of unwanted applications by executing certain scripts. Usually adware is designed to serve banners, coupons, banners, surveys, pop-ups, although, it may serve other ads as well. Another problem with apps like DevModule is that they tend to be designed to promote some fake search engine by changing browser settings such as address of a default search engine, homepage and new tab. It is common that users cannot remove a certain address from the aforementioned settings unless they uninstall the app that is designed to promote it. As mentioned in the introduction, DevModule is capable of accessing sensitive information. It can collect passwords, credit card details, telephone numbers and/or some other information from websites. Its developers could misuse gathered details to steal accounts (e.g. email, social media, banking-related accounts), identities, make fraudulent transactions, purchases, or for other malicious purposes.

There are many apps like DevModule, some examples are NetInput, NetworkHelper and StandardMethod. Typically, adware is advertised as legitimate, useful, software. Although, most of them it is designed only to generate revenue for its developers by serving ads, promoting shady addresses and/or gathering various data. Therefore, apps like DevModule should never be downloaded and installed.

How did DevModule install on my computer?

More often than not potentially unwanted apps are distributed by integrating them in download and/or installation setups of other programs. This distribution method is called "bundling". Offers to download and/or install included apps can be declined via "Advanced", "Custom", "Manual" or other settings, or by unticking certain checkboxes that are available in setups. Unwanted apps get downloaded and/or installed together with other programs when users leave the aforementioned settings unchanged (checkboxes unticked). Sometimes unwanted downloads and/or installations can be caused by clicking deceptive advertisements that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

Download and installation setups that have settings like "Advanced" "Custom", "Manual", some checkboxes, etc., should be always checked for offers to download and/or install unwanted apps. Files, programs should be downloaded only from legitimate, official web pages, and via direct download links. Examples of sources, tools that should not be used neither to download or install programs, files are unofficial pages, third party downloaders, installers, Peer-to-Peer networks like torrent clients, eMule, or other. Advertisements on shady pages should not be clicked as well, they can be designed to open other websites of this kind or cause unwanted downloads, or even installations. Unwanted, unknown or suspicious apps (extensions, plug-ins, add-ons) that are installed on a browser should be removed, programs this kind that are installed on the operating system should be uninstalled too. If your computer is already infected with DevModule, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
