ComboFix is a free malware removal tool that is designed to scan a Windows computer for malware infections and remove them. It was developed by sUBs, a security researcher, and was first released in 2006. ComboFix is known for its powerful and thorough scanning capabilities and is often used as a last resort when other anti-malware tools have failed to remove a persistent malware infection.

ComboFix is designed to run in safe mode and performs a comprehensive scan of a computer’s registry, system files, and folders for known malware infections. It also attempts to remove any malicious files and registry entries that it finds. ComboFix is known for its ability to remove certain types of malware, such as rootkits, that can be difficult to remove using other tools.

It is important to note that ComboFix is a powerful tool that should be used with caution. It is not recommended for inexperienced users and should only be used under the guidance of an experienced IT professional. ComboFix can cause system instability or even cause damage to the operating system if not used correctly.

In recent years, ComboFix has become less widely used as newer and more advanced anti-malware tools have become available. However, it remains a powerful tool for removing certain types of persistent malware infections.
