How to Remove OperativeUnit
OperativeUnit is a Potentially Unwanted Program (PUP) compatible with Macs. It is not installed as a stand-alone application and, instead, it usually shows up as a browser add-on for Safari, Mozilla Firefox, or Google Chrome. This software aims to work silently in the background, and make sure that the changes it brings to your Web browser's configuration will be persistent. These changes concern the default search engine and new tab page you see – OperativeUnit may replace them with a 3rd-party search engine. While OperativeUnit's changes are not harmful in any way, they may undermine your Web browsing experience. Furthermore, the search features presented by OperativeUnit's search engine are likely to be lackluster, and they may often promote sponsored or low-quality content.
You are unlikely to end up installing OperativeUnit intentionally. This software has no official installer, download page, or website. Instead, it is being spread online through the use of fake downloads, bogus installers/updaters, and software bundles abusing misleading installation instructions. Most users are likely to accidentally approve OperativeUnit's installation while dealing with an entirely different piece of software.
If your Web browser settings have been changed without your consent, and you end up being redirected to an unknown website randomly, then checking for PUPs or hijackers active on your system is strongly recommended. The best way to perform this task is to run a suitable Mac security tool.
