How to get rid of the NetworkService adware?

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

What type of app is NetworkService?

NetworkService is an application designed to display advertisements and promote a fake search engine (by changing the web browser's settings). It is uncommon for adware and browser hijackers to be installed on purpose. Thus, apps of this kind are categorized as potentially unwanted applications (PUAs).

NetworkService adware in detail

NetworkService generates advertisements that could open untrustworthy websites. Those ads could open various scams, pages used to promote PUAs, and so on. Also, they could download or even install unwanted applications.

Additionally, NetworkService hijacks a web browser by changing its settings. It changes the default search engine, homepage, and new tab page to a fake search engine (its address). Fake search engines cannot be trusted - their search results could include links to shady pages, or they could redirect users to untrustworthy sites.

NetworkService adware in general

NetworkService displays annoying advertisements and forces users to browse the web using a fake search engine (and prevents users from removing that fake search engine from the web browser's settings). NetworkService is similar to DiscoveryHandler, PathNetwork, and MultiProject.

How did NetworkService install on my computer?

Quite often, adware gets installed through downloaders and installers for other programs (when adware is bundled with other software). It gets permission to be downloaded or installed when users leave "Custom", "Advanced" or other settings available in downloaders or installers unchanged.

Sometimes, software of this type gets installed through ads designed to run certain scripts or fake installers downloaded from deceptive websites. Either way, users do not download and install adware intentionally.

How to avoid installation of potentially unwanted applications?

Avoid finishing downloads and installations without checking (and changing, if necessary) settings available in downloaders or installers. Use official websites and direct links to download software and files. Additionally, avoid clicking on advertisements that appear on questionable websites.

If your computer is already infected with NetworkService, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
