If you believe you have malware on your PC and aren’t sure your anti-virus has removed it, you can use the Microsoft Safety Scanner tool. Safety Scanner, also known as MSERT, is a standalone Windows 10 malware removal tool that can find many malware types.

Microsoft Safety Scanner is a portable malware removal tool

The main difference between Microsoft Safety Scanner (MSERT) and Microsoft’s Malicious Software Removal Tool is its portable nature. Though Safety Scanner works similarly, you won’t need to install it or download additional malware definitions via Windows Update.

Instead, your Microsoft Safety scanner download will always be up to date and include the latest detection patterns. This is beneficial for simplicity, and the lack of installation may allow it to work when other anti-virus solutions are blocked by the malware.

However, it should be noticed that MSERT should not be used as a replacement for other Microsoft anti malware solutions like Windows Defender. Nor should it replace third-party solutions like Malwarebytes. This is because the MSERT does not contain real-time protection. It will not stop a virus infecting you in the first place – only help to clean up particularly stubborn ones.
