If Windows Defender detects a threat on your system, it will take steps to protect your system by blocking or removing the malicious software.
The first step is to identify the threat. Windows Defender uses several techniques to detect and classify threats, including scanning files and monitoring network behavior. If the threat is detected, Windows Defender will alert you with a prompt and provide information about the risk.
Once the threat has been identified, Windows Defender will take action to protect your system. This can include blocking malicious websites, removing malicious files, or quarantining the infected files. In some cases, Windows Defender may also notify you about the threat and display a security alert.
Once the threat is addressed, Windows Defender will monitor your system for future threats. It will continue to scan files, monitor network activity, and take appropriate action.
Windows Defender also offers protection from potentially unwanted programs (PUP) and other programs that could put your system at risk. PUPs are applications that may offer useful functionality, but may also contain adware, spyware, or other malicious code. Windows Defender can detect and block these types of programs before they can cause harm to your system.
In addition to protecting against malicious threats, Windows Defender can also help improve your system’s performance. It can detect and remove unnecessary programs or files that are taking up storage space or slowing down your computer. It can also free up RAM and improve start-up time.
Overall, Windows Defender is an effective tool for protecting your system from malware, ransomware, PUPs, and other threats. It can detect and remove threats quickly, while also providing long-term protection against future threats.
