How to remove CoreSource adware?
Written by Tomas Meskauskas on
What kind of software is CoreSource?
CoreSource generates advertisements and promotes a fake search engine by hijacking a web browser. Most likely, it is distributed using deceptive methods. Thus, it falls into the category of potentially unwanted applications (PUAs). Users often download and install such apps unintentionally.
CoreSource in detail
Ads displayed by CoreSource can lead to pages designed to promote PUAs, scams asking to provide sensitive information, and other untrustworthy websites. Also, this app might show ads designed to run certain scripts (to download or even install unwanted software).
Since CoreSource is also a browser-hijacking app, it changes the search engine, homepage, and new tab page to a fake search engine (its address). Fake search engines can promote dubious pages and (or) show results generated by other shady search engines.

CoreSource adware in general
CoreSource has the qualities of an adware-type and browser-hijacking application. It is worth mentioning that a big part of apps of this type can access/collect various information about their users. More adware examples are DataFile, AnalogSet, and AssistiveConsole.
How did CoreSource install on my computer?
Most adware-type apps get installed via software bundles, deceptive ads, fake installers. It is common for adware to be bundled with other software - to be included in installers. This distribution method works when users do not change "Advanced", "Custom", or similar settings before installing software.
Ads can download or install adware only when designed to run certain scripts. Users download or install unwanted software by clicking on those ads. Fake installers used to distribute adware get downloaded mostly from deceptive pages.
How to avoid installation of potentially unwanted applications?
Always use official pages (or other legitimate sources) to download applications, files. Avoid using other sources for that. Also, do not trust advertisements showing up on questionable, dubious web pages. Deselect unwanted optional downloads and installations before downloading and installing programs.
If your computer is already infected with CoreSource, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
