Mac users may be obliged to deal with a Potentially Unwanted Program (PUP) named ConnectionIndexer if, when downloading free programs from the third-parties, do not read the Terms and Condition linked to the download. Although not threatening, ConnectionIndexer may make some changes to your browser settings and system that may end up causing some unwanted problems.
Once inside your computer, ConnectionIndexer will configure Safe Finder as your Web browser. Although Safe Finder is not considered unsafe and will not cause any harm to your privacy or the security of your computer, the search results you will receive may not be as accurate as the ones provided by Google, Mozilla Firefox, Safari, Internet Explorer, Chrome, etc.
Looks like that the main distribution method used by ConnectionIndexer is a fake Adobe Flash Player update. However, the developers of PUPs and other malware kinds have a lot more ways to spread their malware. Therefore, macOS users need to be attentive all the time if they want to avoid being infected by PUPs, adware, browser hijackers and even threats.
The manual uninstallation of the ConnectionIndexer PUP might be nearly impossible because it possesses some components that may persist on the infected machine after their apparent removal. The recommended removal method that should be used with ConnectionIndexer is a trustworthy Mac security tool.
