How to remove MajorChannelSearch from Mac computers

What is MajorChannelSearch?

MajorChannelSearch is a potentially unwanted applications (PUA) and part of the AdLoad adware family. Like most adware-type applications, it is designed to display various intrusive advertisements. Additionally, this application promotes a fake search engine. Be aware that MajorChannelSearch is distributed and installed through fake Adobe Flash Player installers. People do not generally download or install these apps intentionally.

MajorChannelSearch adware

Typically, adware-type software feeds users with advertisements that are displayed in the form of banners, pop-ups, coupons, surveys, and so on. People who click these ads arrive at various untrusted, potentially malicious pages, or they allow them to execute scripts that cause download/installation of PUAs. Furthermore, MajorChannelSearch promotes a fake search engine, serves ads and operates as a browser hijacker. Typically, these apps promote fake search engines by assigning associated URLs as the address of the default search engine, homepage, and new tab. In most cases, these settings cannot be undone or modified in any other way unless users uninstall the hijacking app that altered them. Note that fake search engines provide misleading results or results generated by other, legitimate search engines (hence their classification as fake). MajorChannelSearch is also likely to collect information relating to users' browsing habits including geolocations, entered search queries, addresses of visited pages, IP addresses, etc. They might also record personal, sensitive information. The developers generate revenue by selling the data to third parties (potentially, cyber criminals) who misuse it in other ways. People who have MajorChannelSearch installed on their browsers or operating systems risk becoming victims of identity theft, suffer monetary loss, experience problems relating to browsing safety, privacy, and so on. Therefore, never download or install any PUAs.

How did MajorChannelSearch install on my computer?

Research shows that MajorChannelSearch is distributed through fake Adobe Flash Player installers. Therefore, it is installed when users expect to update or install Adobe Flash Player. Most PUAs are downloaded or installed through the set-ups of other, regular programs. I.e., when they are included into set-ups as "additional offers". This distribution method is known as "bundling" and is used to trick people into downloading and installing PUAs through the set-ups of other, required programs. In most cases, information about these additional downloads/installations can be found in settings such as "Custom", "Advanced", and other similar sections. Unfortunately, many people fail to check and change the settings, thereby allowing PUAs to be downloaded and installed together with regular software. In some cases, PUAs can be downloaded and installed by clicking deceptive advertisements that run certain scripts.

How to avoid installation of potentially unwanted applications

Do not use unofficial websites, Peer-to-Peer networks (e.g., torrent clients, eMule), third party downloaders, installers or other sources of this kind to download or install software. Use official websites and direct links. Check "Custom", "Advanced" and other similar options of the download or installation setup. Dismiss any offers to download or install unwanted software before completing the process. Intrusive advertisements that are shown on dubious web pages often lead untrusted websites or cause download/installation of unwanted apps. Therefore, do not trust or click these ads. Remove any unwanted, suspicious extensions, add-ons and plug-ins installed on the browser, and programs of this kind installed on the operating system/computer. If your computer is already infected with MajorChannelSearch, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
