What kind of application is Majorlibrary?
Our analysis found that Majorlibrary is a dubious application designed to flood users with annoying advertisements, which could potentially direct them to untrustworthy websites. As a result, we have categorized Majorlibrary as adware. It is advisable for users to avoid having adware installed on their devices.
Majorlibrary adware in detail
Clicking advertisements originating from the Majorlibrary application can cause online security and privacy issues. These ads tend to be intrusive, often guiding users towards dubious websites, thereby exposing them to a spectrum of cyber threats, including malware, phishing scams, and fraudulent schemes.
Interacting with these ads could inadvertently trigger the download of malicious software onto users' devices or lead to pages designed to extract sensitive information, potentially resulting in financial losses or identity theft. Moreover, users might be directed to deceptive pages offering fake giveaways, lotteries, and similar scams.
Moreover, Majorlibrary may harvest various forms of user data, ranging from browsing histories and search queries to IP addresses, geolocation information, and potentially even credit card details or passwords. In some instances, apps like Majorlibrary operate as browser hijackers, gaining unauthorized control over users' browsers to manipulate settings such as the default homepage, search engine, and new tab page.
Browser hijackers disrupt the browsing experience and expose users to potentially harmful content or advertisements. Furthermore, reverting these changes can prove challenging, as browser hijackers often hinder users' efforts to regain control over their browsers without completely uninstalling or removing the app.

How did Majorlibrary install on my computer?
Users often inadvertently install adware while installing free software from questionable sources (e.g., third-party app stores). Additionally, clicking on deceptive ads or links on suspicious websites can trigger the automatic download and installation of adware without users' consent.
Furthermore, users may unintentionally install adware by leaving certain settings/options unchanged during the installation process of other software, where adware is buried within those settings/options.
How to avoid installation of unwanted applications?
To avoid adware, users should be cautious when downloading and installing software from the internet, ensuring they only download from reputable sources and carefully reviewing the installation process to opt out of any bundled adware. Additionally, it is essential to refrain from clicking on suspicious ads or links and to be wary of deceptive pop-ups while browsing.
Regularly updating antivirus and anti-malware software can also help detect and prevent adware infections. Finally, reading user reviews and researching software before installation can provide insights into whether it contains adware or other potentially unwanted programs.
If your computer is already infected with Majorlibrary, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
