I use it in conjunction with ESET and Microsofts own Malicious Software Removal. Every month when a new malicious software removal tool(MRT) comes about and you install that update it runs in the background. Theres no need to set up the tool, it comes with all versions of Windows and as long as you install. I tried using SysInternals AutoRuns and looking at the Scheduled Tasks but was not able to find where it was being started. Your product works fine and scans quickly. Comes bundled with all Windows versions by default. So it is definitely installed and being run daily. The update KB890830 is not installed on this computer.Īccording to the C:\Windows\debug\mrt.log, C:\Windows\System32\MRT.exe is being run daily during the "Automatic Maintenance" window defined in the Action Center section of the control panel. Click the below mentioned link or Scan QR Code to download the tool. The Malicious Software Removal Tool (or KB890830) is a Windows malware-protection offering that updates and runs once a month, and proceeds to remove any threats it finds without user confirmation. We also tried running wusa.exe /uninstall /KB:890830 but it returned the error: Free Bot Removal Tool - For Microsoft Windows.

We've had issues with MRT in the past and want to remove it, but now the script has declined the update and we cannot find anything under the View installed updates section to remove it. We have a script that declines KB890830 updates for our on-premise Windows Update Server, but we recently found someone approved one of the monthly updates before the script could run and the Malicious Software Removal Tool (MRT) was installed on all of our servers.
