DataFile is another dubious application that targets Mac users and then monetizes its presence through intrusive methods. Typically, such applications are not installed by users intentionally. Instead, they are being spread through underhanded distribution methods, such as bundling. This questionable behavior classified DataFile as a PUP (Potentially Unwanted Program).
Once installed on the system, the application will begin to generate countless unwanted advertisements. The advertising materials may appear as pop-ups, banners, in-text links, etc. They may even be injected into unrelated websites. Users who engage with the advertisements risk being redirected to suspicious websites that might be running online tactics, phishing schemes, spreading more PUPs or even malware threats.
At the same time, DataFile also is equipped with browser hijacker functionality. It will establish control over the user's Web browsers and force them to open an unfamiliar page, usually a fake search engine. The promoted address will be set as the browser's homepage, new tab page and default search engine. Users should remember that fake engines cannot produce results on their own. They either redirect the initiated search queries to a legitimate engine or go to a dubious one. Dubious engines can generate results but they will be of low quality and most often will contain numerous sponsored advertisements.
Adware, browser hijackers, and other PUPs also may be spying on the browsing activities on the system. These intrusive applications could be collecting the browsing history, each clicked link, and every initiated search, and transmitting the data to their operators. Additional information, such as various device details also may be collected.
