FreeFixer is a software tool designed to help users remove unwanted software, such as spyware, adware, and other potentially unwanted programs. It scans a user's computer for suspicious files, processes, and registry entries, and provides a detailed report of its findings. The software allows the user to selectively remove or quarantine any identified threats, and also provides a community-based database of known malicious software to aid in the removal process. Additionally, FreeFixer includes a startup manager and file removal tool to help optimize the user's system performance.
