How to remove ModuleService adware from the operating system?

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

What is ModuleService?

ModuleService is an adware-type app with browser hijacker traits. Furthermore, software products within these categories are also considered to be PUAs (Potentially Unwanted Applications).

ModuleService adware

ModuleService adware in detail

Adware enables the placement of third-party graphical content (e.g., pop-ups, banners, surveys, and other intrusive ads) on any visited website and/or different interfaces. In addition to diminishing the browsing experience, the delivered advertisements endanger device/user safety. When clicked on, intrusive adverts redirect to untrustworthy/malicious sites, and some can stealthily download/install software (e.g., PUAs).

Browser hijackers reassign browsers' homepage, default search engine, and new tab/window URLs - to fake web searcher addresses. Hence, new browser tabs/windows opened and search queries typed into the URL bar - redirect to the promoted address.

Fake search engines typically cannot provide search results, so they redirect to Yahoo, Bing, Google, and other legitimate ones. Browser hijackers also use persistence-ensuring techniques to prevent users from recovering their browsers.

What is more, most PUAs have data tracking abilities. Targeted information includes: browsing and search engine histories, IP addresses, personally identifiable details, etc. The gathered data is then monetized by being shared with and/or sold to third-parties (potentially, cyber criminals).

To summarize, the presence of unwanted apps on devices can lead to system infections, serious privacy issues, financial losses, and even identity theft.

Adware in general

UpgradeActivityAccessibilityMethodAccessibleValue, ExpandedActivity, and NetFunctionSearch are some examples of apps within the adware classification. They appear legitimate and offer fake functionalities, and this is typical of nearly all PUAs.

Functionality and user safety are irrelevant, as the only goal of unwanted software is to generate revenue for the developers. PUAs are designed to run intrusive ad campaigns, hijack browsers, cause redirects, and collect private data.

How did ModuleService install on my computer?

PUAs are distributed by using the "bundling" method - packing regular programs with unwanted/malicious additions. Rushed downloads/installations increase the risk of allowing bundled content into the system. Intrusive adverts are also used to proliferate PUAs. Once clicked on, the ads can execute scripts to download/install these applications without user consent. PUAs may have "official" download pages as well.

How to avoid installation of potentially unwanted applications?

It is recommended to research software and download only from official/verified sources. Untrustworthy download channels, e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled content.

When downloading/installing, it is important to read terms, explore available options, use the "Custom/Advanced" settings to opt-out from all additions. Intrusive advertisements appear legitimate; however, they redirect to highly questionable websites (e.g., gambling, pornography, adult-dating, etc.).

In case of encounters with such ads and/or redirects, the system must be inspected and all dubious applications and browser extensions/plug-ins detected - removed from it without delay. If your computer is already infected with ModuleService, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
