DefaultExplorer

DefaultExplorer is an intrusive macOS application, which is often installed without the user's knowledge and approval. The software is not threatening, but it may try to run in the background silently, and then manipulate your Web browser's behavior so that you will see extra advertisements, or get redirected to unknown sites. DefaultExplorer is detected as a Potentially Unwanted Program (PUP) by macOS security products, and even macOS' integrated security features will warn you about the potential trouble it may cause.

macOS' security features are the exact reason why so many users have been asking questions about DefaultExplorer online. When this file tries to run, macOS shows an alert saying 'DefaultExplorer Will Damage Your Computer.' The good news is that while this message may sound scary, DefaultExplorer does not have the ability to cause major problems. As mentioned earlier, its worst ability is to manipulate Web browser settings and behavior.

If you see the 'DefaultExplorer Will Damage Your Computer' message, you should run an up-to-date macOS security scanner to identify and delete components of this program.
