How to remove ExpandedQuest from Mac?

What is ExpandedQuest?

Like most adware-type applications, ExpandedQuest is designed to serve advertisements. Also, it functions as a browser hijacker - it is designed to change certain browser settings to an address of some fake search engine. Additionally, it may be designed to function as data collector. In most cases users download and install apps like ExpandedQuest (browser hijackers, adware) unknowingly, for this reason they are categorized as potentially unwanted applications (PUAs).

ExpandedQuest adware

Adware is a type of software that feed users with surveys, banners, pop-ups, coupons and/or other types of ads. It is common that their ads are designed to open unreliable pages, in some cases they are designed to execute scripts that cause download and/or installation some unwanted software. As mentioned in the first paragraph, ExpandedQuest functions not only as adware but also as a browser hijacker. It means that it changes browser settings such as address of the homepage, default search engine and/or new tab to an address of some fake search engine so that users would visit it when they open a browser, new tab and /or enter search queries into URL bar. In most cases browser hijackers do not allow users to modify, undo the changes that were made by them as long as they are installed. Additionally, ExpandedQuest may be designed to collect information like IP addresses, addresses of visited web pages, entered search queries, geolocations and/or other browsing data, or even some sensitive, personal information. Its developers may misuse collected information to generate revenue by selling it to third parties (who may be cyber criminals) or in some other ways. In such case its users may become victims of identity theft, experience issues related to web browsing safety, online privacy, and/or other problems.

A couple of examples of other apps like ExpandedQuest are AssistiveValue, ProgressElemnt and AnalyzerSearch. Usually apps of this type are useless to their users, they do not include any features, improve browsing experience, etc. On the contrary, most of them are designed only to generate revenue for their developers and can cause users various issues. Therefore, it is advised not to trust (download and install) adware of other types of PUAs.

How did ExpandedQuest install on my computer?

It is common that PUAs are distributed by using a deceptive marketing method called "bundling". It means that apps of this type are distributed by including them in download and/or installation setups of various programs as additional offers. In most cases offers to download and/or install integrated apps can be found and declined in "Custom", "Advanced" and other similar settings of setups (or by unticking certain checkboxes). However, not all users check and change those settings. When they leave them unchanged, they give included apps a permission to be downloaded and/or installed together with the programs that have those apps included in their setups. In some cases users download and/or install various unwanted apps by clicking deceptive ads that are designed to execute certain scripts. It is worthwhile to mention that most of these ads appear on various untrustworthy pages.

How to avoid installation of potentially unwanted applications?

Download and installation setups should be always checked for "Custom", "Advanced" settings and available checkboxes. It is common that they can be used to decline offers to download and/or install additionally included, unwanted software. Advertisements that are displayed on shady websites should not be clicked - they can be designed to promote (open) other questionable websites or even to cause a download and/or installation of unwanted, potentially malicious software. Files, programs should be downloaded from official websites and via direct links. Sources, tools like Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, third party downloaders (and installers), free file hosting pages, etc., should not be used neither to download or install any files, or programs. Unwanted, suspicious apps (extensions, add-ons or plug-ins) that are installed on a browser should be removed from it. Software of this kind that is installed on the operating system should be uninstalled too. If your computer is already infected with ExpandedQuest, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
