WideCluster is the name of an adware-type application with the qualities of a browser hijacker. It can show advertisements and change web browser's settings to promote a fake search engine. Typically, apps like WideCluster are promoted/distributed using questionable methods to trick users into downloading and installing them.
WideCluster adware in detail
WideCluster can show advertisements designed to promote various scams, dubious websites, potentially unwanted applications (PUAs), and so on. Moreover, those ads can be designed to download or install PUAs by running certain scripts.
Web browser's settings that WideCluster changes are the default search engine, homepage and new tab page. It changes them to a fake search engine. That search engine could redirect to potentially malicious sites and (or) show results generated by dubious search engines.

WideCluster adware in general
WideCluster is an untrustworthy application that can display unwanted ads and force users to browse the Internet with a fake search engine. It is similar to CompactFilter, MultiSet, AdvancedServices, and lots of other apps. Users rarely install such apps intentionally.
How did WideCluster install on my computer?
It is common for adware to be bundled with other software. In such cases, adware is mentioned and can be deselected in "Manual", "Custom", or other settings that downloaders and installers have. When users download or install software without making changes in those settings, they also agree to download or install adware.
Ads and fake installers can cause unwanted installations too. Those ads usually appear on shady websites. They are designed to run certain scripts. Fake installers are promoted on deceptive pages.
How to avoid installation of potentially unwanted applications?
Applications (and files) should be downloaded from official, legitimate pages. Downloads from Peer-to-Peer networks, unofficial websites, etc., might install unwanted apps. Downloaders and installers with any settings should be checked for optional downloads or installations. Advertisements showing up on shady web pages should not be clicked as well.
If your computer is already infected with WideCluster, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
