Remove CacheImprovement
CacheImprovement is identified as a Potentially Unwanted Program (PUP) compatible with all Mac operating systems. It is a shady browser plug-in that will manipulate the settings of your default Web browser, ultimately forcing redirects to low-quality search engines. The plug-in could also introduce unwanted ads and other marketing content that shows up in new tabs or overlays on top of legitimate websites.
As the name of the program suggests, CacheImprovement may be marketed as a great tool to enhance your browsing experience by improving the performance of the browser's cache. However, you can rest assured that CacheImprovement has nothing good to offer – the sole purpose of this dodgy application is to bring traffic to 3rd-party sites by making intrusive changes to browser settings.
CacheImprovement is often introduced to Mac systems through a shady ad, misleading software installer, or a fake download. Users are unlikely to come across such PUPs if they stick to visiting legitimate sites and downloading software from trustworthy sources. Usually, it is best to have an extra layer of protection in the shape of a reliable Mac antivirus software suite.
If the Web browser on your Mac system is behaving weirdly and redirecting you to unknown sites, then you should immediately run a security scanner to find and remove PUPs and hijackers, which might be responsible for this.
