If you have DataFile installed on your Mac, you may be experiencing numerous advertisements, browser redirects, and an overall worsened performance of your machine.
Adware that belongs to AdLoad is also known to be quite persistent and capable of circumventing Mac’s built-in protection mechanisms. Because of this, installing an additional anti-malware program to check your operating system may be recommended. Depending on the symptoms your device is experiencing, you can decide for yourself which is the next best step to take.

DataFile Mac Adware – How Did It Get Installed on My Mac?
After we established what DataFile adware is, it is time to learn more about its distribution ways.
Several techniques are usually deployed for the distribution of the DataFile adware. A significant distribution technique is software bundling. Bundling revolves around programs that pretend to be useful and legit but come bundled with ad-supported apps.
The purpose of bundling is quick monetization. Commonly used software may deliver unwanted apps such as Ultratech. This includes media players, file converters, weather toolbars, online streaming apps, etc.
The installers of these programs often present optional offers or free extras. At the same time, they are not designed to appropriately disclose information about added apps. That’s how users fail to notice their presence during the installation of whatever software they wanted to download.
Other scenarios include users interacting with suspicious pages (torrenting and online streaming websites, adult pages, free online games, etc.). On these pages, users may click on suspicious links, banners, and offers. The result may be an unnoticed download and install of a potentially unwanted program.
A very wide-spread propagation is using a fake Flash Player update. Your browser may generate a fake error message, claiming that “Adobe Flash Player Is Out of Date”. Interacting with the message, like clicking on the download button it provides, will surely install an adware on your Mac.
N.B. Once started on your Mac, such a program could access all installed browsers’ settings to apply significant changes. One of these changes often affects the default search engine in your preferred web browser. If your default search engine is altered without your consent, then don’t waste time but go check your macOS security. This problem is a definite sign that a suspicious piece of software has sneaked into your system.
Furthermore, as long as files associated with the DataFile adware are running on your Mac, you may be a victim of unsolicited data collection.

Shady adware developers may use your data records in targeted advertising campaigns. Once the data is available on their servers, it can be used for the identification of your online interests.
