More about InfoMajorSearch adware

Clicking on advertisements displayed by InfoMajorSearch can open shady websites (e.g., download pages for questionable apps, various scams, deceptive sites asking to provide sensitive information). Moreover, it can lead to unexpected downloads or even installations. Thus, it is highly advisable not to trust ads generated by apps like InfoMajorSearch.

Our team has examined plenty of apps like InfoMajorSearch. Part of them hijacked web browsers by replacing the default search engine, homepage, and new tab page with a fake search engine. They forced us to browse the web using search engines that generate misleading results, redirect to shady websites, or show results generated by other dubious search engines.

Adware in general

Advertising-supported applications bombard users with unwanted advertisements. They can also change browser settings (hijack web browsers) and collect data. Most of them are promoted/distributed using deceptive methods. More examples of adware-type apps are GeneralProjectSearch, NetDivision, and DomainNameProduct.

How did InfoMajorSearch install on my computer?

In most cases, unexpected installations are caused via shady advertisements, files downloaded from deceptive websites (and other unreliable sources), and installers for software bundled with unwanted apps. Installers containing unwanted apps have "Advanced", "Custom", or other settings. Unwanted apps get installed when installations are finished without changing those settings.

InfoMajorSearch is distributed using fake Adobe Flash Player installers. These installers are distributed using deceptive websites claiming that Adobe Flash Player is out of date. Those websites are promoted mainly through other pages that use rogue advertising networks.

How to avoid installation of unwanted applications?

Download applications (and files) from official pages and use direct links. Other sources (like P2P networks, third-party downloaders, shady web pages, etc.) can be used to distribute questionable or even malicious software. Also, do not click on shady ads (ads appearing on dubious pages) and deselect unwanted apps before installing any software.

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