Windows defender is a build in antivirus software which offers instant solutions to malware in PC’s where there is no third-party antiviruses installed. It is fairly good as it provides the basic tools to keep your system secured when there is no antivirus installed but obviously it is no match for antiviruses like Kaspersky, Bitdefender or ESET.
Not all viruses and unwanted software can be removed when Windows is running as they load with Windows operating system. This is the reason many antivirus programs request user to restart the system in order to completely remove the detected malicious code.
For the convenience of users many antivirus developers are providing users with offline versions of their software in order for users to scan their PC and remove threats that cannot be otherwise removed using standard method.
Windows has also been providing Windows Defender Offline Tool for years to help users remove malware and other potentially unwanted programs from PC without booting into Windows.
