When new updates became available at Windows Update today, I selected all of them and installed. Everything went fine until the Malicious Removal Tool (KB890830). It just stuck there for 20 minutes, so I finally decided to hit Cancel, and restarted my computer (to apply the successfully installed updates).

After windows rebooted, the Malicious Removal Tool showed up on Windows Update's list of successfully applied updates, the one after it (IE compatibility view list KB982664) showed up as canceled. It is not the first time this problem happened to me. (Last time it was also stuck on the Malicious removal tool. I already ran the MS Fix it to reset my Windows Update (the aggressive option). Why does it keep happening? I opened C: WINDOWS Debug MRT.TXT and scrolled to the end of the file and saw the following entry with today's date. Microsoft Windows Malicious Software Removal Tool [version Month Year] Started On [Day Month Date Time Year] I am running Vista SP2.

Mar 20, 2016. Turns out the Automatic Maintenance tasks are managed by C: Windows System32 MSchedExe.exe and the Scheduled Tasks under the Microsoft Windows TaskScheduler folder. It then will run other tasks that are defined but don't have a specified trigger, one being the MRT_HB task under. Sep 17, 2010. The Microsoft Malicious Software Removal Tool does not replace an antivirus product. It is strictly a post-infection removal tool. KB890830 lists the three key areas in which the tool differs from an antivirus application. The tool removes malicious software from an already-infected computer. Antivirus products.

Anti-Malware: MSE, SuperAntiSpyware, and MalwareBytes's Anti Malware. No Norton Anti-Virus, and got McAfee removed using their customer products removal tool. Thanks a lot for your help.

Last time it was also stuck on the Malicious removal tool. I already ran the MS Fix it to reset my Windows Update (the aggressive option). Why does it keep happening?

In your (14 Jul-10 &ff), we learned that: 1. You'd done a clean install shortly before you installed MSE; and that. While you uninstalled the reinstalled McAfee free-trial, you did not download/run the BEFORE you installed MSE. Although I then had you run the tool, reset Internet Explorer and reset Windows Update by running the KB970158 Fix It in Default & Aggressive modes, I don't know how long you'd been running MSE before we did all that so there's a very small chance that the steps you took didn't resolve the behavior. That being said. QUESTION: Did all of the other updates released on 10 Aug-10 install successfully? [yes/no] ACTIONS: 1.

Download the Malicious Software Removal Tool (MSRT), saving it to your desktop: 2. Temporarily disable (a) all S*PERAntiSpyware's realtime protections & (b) MBAM (but only if it's the paid version) & (c) ZoneAlarm (if it's still installed) AND THEN enable the Windows Firewall. Double-click on the file you saved in #1 above (i.e. The Police Regatta De Blanc Rar. , windows-kb890830-v3.10.exe) and run a Quick scan.

Don't TOUCH the computer until the run completes (allow at least 30 minutes). Assuming the Quick scan in #3 went well, now run a Full scan. Again, don't TOUCH the computer until the run completes (could take an hour or more). [Comment: When you download/run the MSRT as part of installing updates, the scan will take much longer to complete (vs. Running it manually) as your system's kinda 'tied-up' by Automatic Updates and the entire updating process cannot complete until after the MSRT has run. In short, be much more patient next time around.] 5.

Now open the log (C: WINDOWS Debug MRT.TXT) & go to the very bottom. Highlight the last two (2) entries (i.e., the results of the scans you did in #3 & #4 above) & copy them to your clipboard. Open a reply to my post & paste the contents of your clipboard into your reply along with your answer to the QUESTION above.

~~~~~~~~~~~~~~~~~~~~~~~ [1] With MSE installed, the realtime protections included in S*PERAntiSpyware and/or the paid version of MBAM and/or ZoneAlarm (any version) might be 'overkill' for your computer. In other words, the realtime protections of MSE's anti-virus & anti-spyware components might be hampered by the realtime protections included with the other apps.

We have a script that declines 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. 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 also tried running wusa.exe /uninstall /KB:890830 but it returned the error: The update KB890830 is not installed on this computer.

According 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. So it is definitely installed and being run daily. I tried using and looking at the Scheduled Tasks but was not able to find where it was being started. How can we disable or uninstall the Malicious Software Removal Tool on our Windows Servers to prevent it from running? Turns out the Automatic Maintenance tasks are managed by C: Windows System32 MSchedExe.exe and the Scheduled Tasks under the Microsoft Windows TaskScheduler folder.

It then will run other tasks that are defined but don't have a specified trigger, one being the MRT_HB task under Microsoft Windows RemovalTools. Here you can see it calling MRT.exe to run the scan, and the last run time matches the information from the Action Center: If you disable this Scheduled Task it should prevent the Malicious Software Removal Tool from running. You also can delete the task and the MRT.exe program using the following in an elevated PowerShell prompt: Unregister-ScheduledTask -TaskName 'MRT_HB' -TaskPath ' Microsoft Windows RemovalTools ' -Confirm:$false Remove-Item 'C: Windows System32 MRT.exe' -Force Note, however, that if you haven't disabled the KB890830 update in WSUS or via it likely will be reinstalled, as MRT gets updated every patch Tuesday.
