Yes, Windows Defender can detect malware. Windows Defender is a built-in antivirus program that is included with the Windows operating system. It is designed to protect your computer from malicious software programs such as viruses, worms, trojans, rootkits, and other types of malware. It is generally considered to be a good basic security tool for protecting your computer against these types of threats.
Windows Defender works by scanning for known malicious programs in the files, programs, and processes on your computer. When it detects a problem, it will alert you and allow you to take appropriate action. In some cases, it may even be able to remove the threat automatically. Windows Defender also monitors your system for suspicious activity, such as a program trying to connect to the internet without your permission.
Windows Defender is regularly updated with new malware signatures from Microsoft. This means that it is continually improving its ability to detect new threats. It is important to keep your copy of Windows Defender up-to-date to ensure that it is as effective as possible.
Windows Defender also has advanced features such as cloud-based protection, which helps detect and stop emerging threats. It also includes a feature called “Controlled Folder Access” which restricts untrusted applications from accessing certain folders on your computer.
Overall, Windows Defender is a powerful malware detection tool that helps to keep your computer safe. It is important to ensure that it is kept up-to-date with the latest malware signatures to ensure optimal security. While it may not be as sophisticated as some third-party antivirus programs, it is still a very effective tool for protecting your computer from malicious software.
