How to remove UniversalHandler from Mac

What kind of application is UniversalHandler?

After examining UniversalHandler, we learned that it is an untrustworthy application designed to generate intrusive advertisements. Apps of this type are classified as adware (advertising-supported applications). It is uncommon for adware to be downloaded and installed willfully. We discovered UniversalHandler after using a fake installer.

UniversalHandler adware in detail

Clicking on advertisements generated by UniversalHandler opens shady websites. For example, pages requesting sensitive information, encouraging to download dubious apps, urging to call fake technical support numbers, asking permission to show notifications, etc. Also, clicking them can cause unexpected downloads or even installations.

After examining numerous apps similar to UniversalHandler, we learned that sometimes they can hijack web browsers by changing their settings. In such cases, they not only show unwanted ads but also force users to browse the Internet using fake search engines. Search engines of this kind promote untrustworthy websites and (or) show results by shady (or legitimate) search engines.

Adware in general

Adware is often promoted as useful, legitimate software. Nevertheless, it always displays intrusive advertisements that may open untrustworthy pages. Sometimes, adware can access sensitive information. Thus, it is strongly recommended not to install adware and remove already installed software of this type as soon as possible.

More adware examples are MinimalEnergy, TeachPad, and OperationReview.

How did UniversalHandler install on my computer?

UniversalHandler is distributed via a fake Adobe Flash Player installer that can be downloaded from various deceptive websites. Also, adware can be installed via untrustworthy ads designed to run certain scripts and software bundles.

When adware is bundled with other apps, installers have "Advanced", "Custom", or other settings. Users install adware alongside other software when they leave those settings unchanged. Either way, users rarely download and install adware on purpose.

How to avoid installation of unwanted applications?

Do not complete downloads and installations until unwanted apps (optional downloads and installations) are deselected. Also, do not click on advertisements displayed on suspicious pages or allow such pages to show notifications. Download apps from official pages and stores (do not use third-party downloaders, P2P networks, and similar sources).

If your computer is already infected with UniversalHandler, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.

The redirects are likely to remain even after removing the application itself. Thus, you'll have to restore them manually.

Step 1: Click on the gear icon in the Dock to navigate to the system settings. If the icon is not present in the Dock, you can find it in the Launchpad.
