PracticalSystem Mac Virus Removal Guide

PracticalSystem is another nasty program that has been launched by a company that appears to be a vendor of many suspicious, unwanted, and potentially harmful applications that target Mac users. PracticalSystem is yet another product in a long line of junkware. Rest assured that there’s nothing useful about this program. The PracticalSystem program acts in a contrary way once installed on your Mac. It was created to collect private data and spread more PUPs (potentially unwanted programs.)

PracticalSystem Virus on Mac – How Does It Work?

First of all, the browser hijacker gets into your system through junkware that’s attached to otherwise useful programs. “Free” software developers are especially prone to pulling this trick since the data collected by the hijackers can be very profitable (more on that later.)

The racket works like this – while installing a program, maybe a virtual disk tool or a browser extension, you agreed to have Automator as your default search engine. Can’t remember? That’s OK. The potentially unwanted programs are programmed to hide these options in the Custom, Advanced, or Slow portions of the install wizard.

PracticalSystem can affect Google Chrome, Mozilla Firefox, Opera, Safari, and other browsers. Soon after its installation, PracticalSystem becomes able to assign the homepage, default search engine, and new tab URL settings to a strange search engine. This issue can significantly diminish your browsing experience.

The design may be very similar to any other search engine, including Google, Bing, or DuckDuckGo but looks can always be deceiving. As we’ve already established, PracticalSystem uses shady methods of distribution. The inconspicuous design also has a purpose.

Since most people don’t even realize that the site is malicious, they simply tolerate it on their systems. You’d be surprised at how many people don’t even notice a difference.

How does it monetize its presence on affected Mac devices? PracticalSystem virus collects data from the searches. Think about everything you type into your favorite search engine…

  • Your interests.
  • Places you want to visit.
  • Health problems you may have.
  • Services that you need.

That info is very valuable for ad targeting. Google, Facebook, and other big-name ad companies also implement this tracking, but they also provide a useful product. Second-rate advertising tools like Automator want a piece of that pie and the only way they can get it is through hijackers.
