How to remove ElementaryUnit from Mac?

What is ElementaryUnit?

Since ElementaryUnit is classified as adware, it serves advertisements. Although, it functions as a browser hijacker too - it promotes the d2sri.com address (a fake search engine) by changing certain Safari browser settings. Additionally, ElementaryUnit can read sensitive information from browsers that have it installed on them. In most cases users download and install adware unknowingly, unintentionally. For this reason ElementaryUnit and other apps of this type are called potentially unwanted applications (PUAs). It is known that this particular app is distributed via fake installer that is disguised as installer for Adobe Flash Player.

ElementaryUnit adware

It is common that adware serves advertisements that, if clicked, open questionable websites. In some cases those ads can be designed to cause download, or even installation of some unwanted application by executing certain scripts. Some examples of types of ads that adware serves are banners, coupons, surveys, various pop-up ads. Furthermore, ElementaryUnit changes some of the browser settings to d2sri.com - the address of a fake search engine. As a rule, apps that promote fake search engines change browser settings such as address of a default search engine, homepage and new tab. D2sri.com is a fake search engine because it provides results generated by Yahoo - it redirects users to search.yahoo.com. Another problem with ElementaryUnit is that it can read sensitive information such as credit card details, passwords, telephone numbers, and some other personal details. Such information can be misused to steal identities, personal accounts, make fraudulent purchases, transactions, and/or for other malicious purposes. These are the main reasons why ElementaryUnit application should never be installed.

There are many other apps that function similarly to ElementaryUnit. For example, ProductiveRotator, ExpandedCommand and ChangeParameter. As a rule, they are designed to generate revenue for developers by collecting various information, serving advertisements and/or promoting some fake search engine (its address). It is common that such apps are advertised as useful, legitimate. However, they are useless to their users and can be the reason behind problems like identity theft, monetary loss, issues related to online privacy, browsing safety, etc.

How did ElementaryUnit install on my computer?

It is known that ElementaryUnit can be installed via fake installer that supposed to install Adobe Flash Player. It is worthwhile to mention that in some cases fake installers can be designed to install malware (e.g., ransomware, some Trojan). Another way to distribute PUAs is to include them in download and/or installation setups of other programs as additional offers. This distribution method is known as "bundling". It works when users download and/or install programs that have PUAs integrated in their setups without changing settings like "Custom", "Advanced", or other settings. Additionally, unwanted apps can get downloaded and/or installed via deceptive ads that are designed to execute certain scripts. However, it cannot be caused without clicking those ads.

How to avoid installation of potentially unwanted applications?

Third party downloaders, installers, unofficial pages, Peer-to-Peer networks (e.g., torrent clients, eMule), etc., can be used as tools to distribute unwanted, potentially malicious applications. Therefore, any programs and files should be downloaded only from official pages and via direct links. Download and/or installation setups that include "Custom", "Advanced" and other settings can be used to distribute unwanted apps too. It is advised to always check the aforementioned settings before completing downloads and/or installations. Intrusive ads that appear on various untrustworthy pages should not be clicked as well: they can be designed either to open shady pages or download, install unwanted software by executing certain scripts. Any suspicious, unwanted extensions, plug-ins and/or add-ons that are installed on a browser should be uninstalled from it. The same applies to programs of this kind that are installed on a computer. If your computer is already infected with ElementaryUnit, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
