OptimalHelper Hijacker on Mac – Distribution and Description

The primary technique which might have delivered OptimalHelper on your Mac is software bundling also known as packing. Therefore, the unwanted browser hijacker might have entered your Mac as an optional free app added to the installer of a free third-party application that you’ve recently installed. Such apps are hosted on questionable third-party sites that seem as if they are legitimate but are dangerous instead.

Bundling may not be the only technique that installs OptimalHelper hijacker on Mac. The undesired app might end up on your computer after an installation of a fake software update. Some fake Flash Player updates, for example, were noticed to add bogus applications on Mac operating systems.

Once set up on your Mac, the OptimalHelper has the chance to transform the way you use your Mac for the worse. Claiming to be a useful application is something that is common for such pesky applications but the facts indicate that they lower macOS security by forcing victims to use hoax search engines. Sometimes hijackers are the reason for the very persistent issue Google redirects to Yahoo.

In the case of OptimalHelper, the app was registered to add its own bogus search engine. So, if it has infected your Mac, you might see the domain Search.optimalhelper.com to be placed on the homepage, new tab page, and default search engine in the installed web browser.

In addition, the OptimalHelper hijacker on Mac might act as adware too. Once it has been added to the system, it may also begin to deliver the following promotions and ads:

  • Ad-supported search results showing up on a hoax search engine in your web browser.
  • Redirects to third-party sites.
  • Pop-ups.
  • Push ads.
  • Banners.

The ads might leave cookies and other trackers that record specific data. They might additionally be dangerous for your online security if linking to high-risk internet sites like:

  • Phishing sites.
  • Scam websites.
  • Sites that may be phony tech support rip-offs.
  • Risky sites.

Even if OptimalHelper is not a typical Mac virus, it is still indirectly harmful to your computer and must be removed from it.
