    How to Use Malicious Software Removal Tool in Windows

    information   Information
    The Microsoft Windows Malicious Software Removal Tool (MSRT) helps remove malicious software from your computers that are running Windows 10, Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Vista, Windows Server 2003, Windows Server 2008, or Windows XP.

    The Microsoft Malicious Software Removal Tool does not replace an antivirus product. It is strictly a post-infection removal tool. Therefore, we strongly recommend that you install and use an up-to-date antivirus product. If you like, Windows 10 already has Windows Defender included for antivirus.

    The Microsoft Malicious Software Removal Tool differs from an antivirus product in three key ways:
    • The tool removes malicious software from an already-infected computer. Antivirus products block malicious software from running on a computer. It is significantly more desirable to block malicious software from running on a computer than to remove it after infection.
    • The tool removes only specific prevalent malicious software. Specific prevalent malicious software is a small subset of all the malicious software that exists today.
    • The tool focuses on the detection and removal of active malicious software. Active malicious software is malicious software that is currently running on the computer. The tool cannot remove malicious software that is not running. However, an antivirus product can perform this task.

    This tutorial will show you how to open and use the Malicious Software Removal Tool (MSRT) to scan and remove specific prevalent malicious software in Windows.

    I've always been a bit confused about this thing. Windows has Defender now. So isn't this redundant? Defender and other antiviruses monitor the system in real time as well as give options for scheduled or manual scans.

    Hello Crimson,

    No. They have different purposes.

    The Microsoft Malicious Software Removal Tool does not replace an antivirus product. It is strictly a post-infection removal tool. Therefore, we strongly recommend that you install and use an up-to-date antivirus product.

    What's the different purpose? Like if I find out I'm infected with a virus. Post-infection, wouldn't I be able to just run the Defender scan? And it scans and removes it? Or say I'm using a third party anti-virus. Can't I just use that instead of this tool?

    Technically you could use both to do so.

    Think of it like Windows Defender as prevention, and MSRT as clean up after infected.

    Of course, there's no guarantee that either will be able remove the infection since it all depends on if both have updated definitions, and if the infection was defined and included in the definitions to be able remove.

    Right which applies to any anti-virus. Not sure why they would have it from MS side. Defender can now be used as clean up to fix infections. Why have a separate tool for that?

    I mean sure I can have multiple different antivirus for added protection. It's actually sometimes necessary on an infected computer to go into safe-mode, and run scans with different anti-viruses. I usually have Avast installed with Defender disabled as standard protection.

    But if I'm dealing with an infected system, I install the latest Malwarebytes in addition to whatever anti-virus is already installed. Then use whatever anti-virus is installed to run full scan in safe-mode. And again with Malwarebytes as an extra scan. Like I can also, on top of this, run the MSRT thing.

    Either way, if a anti-virus is already installed such as Defender or Avast which all have the ability to remove viruses as clean up after infection, I don't really see anything else special that the MSRT does that a normal anti-virus scan wouldn't be able to do. It was released before MS Security Essentials and the new full anti-virus-Defender. So perhaps in the past, it might have been useful?

    I guess I'd use it in the same way as I use Malwarebytes. As an extra scan in safe-mode to fix an already infected computer. Keep regular antivirus on, monitoring, and doing regular full scans. For infected computers, install latest Malwarebytes and MSRT, as additional scanners.

    Yeah, it's pretty much just another tool to use as needed.

    Oh OK.

    I guess it's like some kind of HiJack this?
