How to remove Jirin.app (Mac)

What is Jirin.app

Jirin.app is a type of adware that specifically targets Mac computers, often causing significant disruption by injecting advertisements into websites and redirecting browser search queries. This software is categorized as a potentially unwanted program (PUP) due to its intrusive behaviors, which include hijacking the browser’s homepage and search engine to display ads not originating from the sites being browsed. Once installed, Jirin.app begins to modify browser settings without permission, redirecting search queries through its own search system, likely to generate advertising revenue. This redirection often leads to search results from less reputable sources, such as Yahoo Search, which are used to maximize ad impressions. The presence of Jirin.app on a Mac can be identified by unexpected changes in the browser’s homepage or search engine, frequent redirects to unfamiliar websites, and the appearance of new tabs displaying advertisements. Removing Jirin.app involves several steps, starting with the identification and removal of any malicious profiles that may have been installed on the system to enforce unwanted browser behavior. Users should also check for and delete any suspicious applications from their Macs. Resetting the affected browsers to their default settings is recommended to undo the changes made by the adware. For thorough removal, running a scan with reputable antivirus software, such as Spyhunter for Mac, is advisable to ensure all components of the adware are eliminated.

How Jirin.app infects Mac computers

Jirin.app typically infiltrates Mac systems through deceptive distribution methods. Users may inadvertently install Jirin.app when it is bundled with other software, especially free applications downloaded from the internet. This method, known as “bundling,” is common for adware distribution. Users install the desired software along with the bundled unwanted program without realizing it. Another common entry point for Jirin.app is through misleading advertisements or pop-ups that prompt users to install updates or other software that is supposedly necessary. Clicking on these ads can trigger the adware installation process.
