Description
Detects the IOBit Unlocker Extension being registered. IObit Unlocker is a utility designed to resolve issues involving files or folders that cannot be deleted, moved, or renamed due to being locked by other processes or applications in Windows. It’s a powerful tool that can “unlock” these files or folders, terminating any processes that are using them. This allows users to manipulate these previously inaccessible files or folders as needed.
