Can Windows Defender detect rootkits?

Yes, Windows Defender can detect rootkits.

Rootkits are malicious programs that can be used to gain access to a computer system without authorization. Rootkits allow attackers to hide their malicious activities and also to gain access to privileged information. They often operate silently, so users remain unaware of the presence of a rootkit on their machine.

Windows Defender is an anti-malware program designed to protect computers from malicious threats, including rootkits. It is included with Windows 10, Windows 8, and Windows 7, though it must be activated manually on those operating systems. Windows Defender includes rootkit detection technology, which can detect the presence of rootkits on a computer system.

To detect rootkits, Windows Defender uses several detection techniques. These include behavioral monitoring, where it monitors for suspicious activities that may indicate the presence of a rootkit. It also scans files and processes on the system, looking for any known rootkit patterns or other irregularities. Additionally, Windows Defender can scan drivers, kernel modules, and system services, as rootkits may sometimes be found in these areas. Finally, Windows Defender can periodically analyze memory dumps and check for rootkit-like behavior.

When a rootkit is detected, Windows Defender will quarantine it, preventing further infections or damage. Windows Defender can also help users remove rootkits by providing the appropriate tools and guidance.

Overall, Windows Defender is capable of detecting and removing rootkits on Windows systems. By using a combination of behavioral and signature-based scanning, Windows Defender can effectively detect rootkits and take action to protect a computer system.
