Should I disable Windows Defender SmartScreen?
Windows Defender SmartScreen is a built-in feature of Windows 11 that provides a layer of protection against malware and phishing attacks. While it can be disabled, it should only be done after careful consideration.
SmartScreen helps protect your PC by warning you before you run unrecognized apps. However, sometimes, it can block unrecognized apps. You may get a Microsoft defender SmartScreen prevented an unrecognized app from starting message.
This can prevent these apps from launching, which can be frustrating, especially if these are your most used apps.
Other reasons why disabling Windows Defender SmartScreen is a bad idea:
- Makes your computer vulnerable to malware attacks – SmartScreen filters out malware before it can infect your computer. If you disable this feature, you’ll have no protection against malicious software like ransomware or spyware.
- Your credentials become less secure – SmartScreen helps prevent unauthorized access to sensitive information such as your email address, credit card number, and password when completing online forms on websites that don’t use HTTPS encryption.
- You’re more likely to download unsafe apps – SmartScreen also checks apps when they’re installed on your computer and warns you if an app has been reported as unsafe by other users or by Microsoft itself.
