Yes, Windows Defender will notify you when malware is detected on your system.
Windows Defender is a built-in antivirus solution that comes as part of Windows operating system for Microsoft users. It is designed to protect computers from online threats such as viruses, spyware, ransomware, and other malicious software. Windows Defender is active by default in Windows 10 and it runs in the background to detect any threats before they can damage your computer.
When Windows Defender finds a virus or other threats, it will notify you with an alert. The alert will include a description of the threat and what action Windows Defender took against it. You can then take further steps to protect your computer, such as downloading additional antivirus software or running a full scan.
When an alert appears, it will be shown in the Action Center in the notification area. You can also see an alert by opening the Windows Defender Security Center and scrolling down to the Virus & Threat Protection section. Here you’ll find a list of recent notifications related to threats that Windows Defender has blocked.
When Windows Defender detects a threat, it takes one of two actions: it either quarantines the file and removes it from the system, or it deletes the file and removes it completely. Depending on the severity of the threat, it may also deny access to it or block potential online communication.
Overall, Windows Defender does a good job of keeping your computer safe from malware. It provides regular alerts if it detects anything malicious, allowing you to take the necessary steps to protect your computer. It’s important to note, however, that Windows Defender is only effective against certain types of malware, so you may want to consider additional antivirus protection.
