The following example is an Mrt. The following is an example log file where no malicious software is found. The following is a sample log file in which errors are found. For more information about warnings and errors that are caused by the tool, go to the following article in the Microsoft Knowledge Base:.
Operation failed. Action: Clean, Result: 0xE. Please use a full antivirus product! When you run the tool by using a startup script, error messages that resemble the following error message may be logged in the Mrt. Note The pid number will vary. This error message occurs when a process is just starting or when a process has been recently stopped. The only effect is that the process that is designated by the pid is not scanned. This has been observed only in the removal of certain rootkit variants.
When I test my startup or logon script to deploy the tool, I don't see the log files that are being copied to the network share that I set up. This is frequently caused by permissions issues. For example, the account that the removal tool was run from does not have Write permission to the share. To troubleshoot this, first make sure that the tool ran by checking the registry key.
Alternatively, you can look for the presence of the log file on the client computer. If the tool successfully ran, you can test a simple script and make sure that it can write to the network share when it runs under the same security context in which the removal tool was run.
How do I verify that the removal tool has run on a client computer? You can examine the value data for the following registry entry to verify the execution of the tool. You can implement such an examination as part of a startup script or a logon script. This process prevents the tool from running multiple times. Every time that the tool is run, the tool records a GUID in the registry to indicate that it has been executed. This occurs regardless of the results of the execution.
The following table lists the GUID that corresponds to each release. How can I disable the infection-reporting component of the tool so that the report is not sent back to Microsoft? An administrator can choose to disable the infection-reporting component of the tool by adding the following registry key value to computers. If this registry key value is set, the tool will not report infection information back to Microsoft.
In the March release, data in the Mrt. Why was this data removed, and is there a way for me to retrieve it? Starting with the March release, the Mrt. To make sure of compatibility, when the March version of the tool is run, if an ANSI version of the file is on the system, the tool will copy the contents of that log to Mrt.
Like the ANSI version, this Unicode version will be appended to with each successive execution of the tool. Need more help? Expand your skills. Get new features first. The license terms are only displayed for the first time that you access Automatic Updates. Note After you accept the one-time license terms, you can receive future versions of the MSRT without being logged on to the computer as an administrator.
If it detects malicious software on your computer, the next time that you log on to your computer as a computer administrator, a balloon appears in the notification area to make you aware of the detection.
If the tool finds malicious software, you may be prompted to perform a full scan. We recommend that you perform this scan. A full scan performs a quick scan and then a full scan of the computer, regardless of whether malicious software is found during the quick scan.
This scan can take several hours to complete because it will scan all fixed and removable drives. However, mapped network drives are not scanned. If malicious software has modified infected files on your computer, the tool prompts you to remove the malicious software from those files.
If the malicious software modified your browser settings, your homepage may be changed automatically to a page that gives you directions on how to restore these settings. You can clean specific files or all the infected files that the tool finds. Be aware that some data loss is possible during this process. Also, be aware that the tool may be unable to restore some files to the original, pre-infection state. The removal tool may request that you restart your computer to complete the removal of some malicious software, or it may prompt you to perform manual steps to complete the removal of the malicious software.
To complete the removal, you should use an up-to-date antivirus product. Reporting infection information to Microsoft The MSRT sends basic information to Microsoft if the tool detects malicious software or finds an error. This information will be used for tracking virus prevalence. No identifiable personal information that is related to you or to the computer is sent together with this report.
The MSRT does not use an installer. Typically, when you run the MSRT, it creates a randomly named temporary directory on the root drive of the computer. This directory contains several files, and it includes the Mrtstub.
Most of the time, this folder is automatically deleted after the tool finishes running or after the next time that you start the computer.
However, this folder may not always be automatically deleted. In these cases, you can manually delete this folder, and this has no adverse effect on the computer.

If you are an IT administrator who wants more information about how to deploy the tool in an enterprise environment, see Deploy Windows Malicious Software Removal Tool in an enterprise environment. Except where noted, the information in this section applies to all the ways that you can download and run the MSRT:. You must log on to the computer by using an account that is a member of the Administrators group.
If your logon account does not have the required permissions, the tool exits. If the tool is not being run in quiet mode, it displays a dialog box that describes the failure.
If the tool is more than days 7 months out of date, the tool displays a dialog box that recommends that you download the latest version of the tool. Runs in detect-only mode. In this mode, malicious software will be reported to the user, but it will not be removed. When you download the tool from Microsoft Update or from Automatic Updates, and no malicious software is detected on the computer, the tool will run in quiet mode next time. If malicious software is detected on the computer, the next time that an administrator logs on to the computer, a balloon will appear in the notification area to notify you of the detection.
For more information about the detection, click the balloon. When you download the tool from the Microsoft Download Center, the tool displays a user interface when it runs. Each release of the tool helps detect and remove current, prevalent malicious software.
This malicious software includes viruses, worms, and Trojan horses. Microsoft uses several metrics to determine the prevalence of a malicious software family and the damage that can be associated with it.
This Microsoft Knowledge Base article will be updated with information for each release so that the number of the relevant article remains the same. The name of the file will be changed to reflect the tool version. The following table lists the malicious software that the tool can remove. The tool can also remove any known variants at the time of release.
Therefore, we strongly recommend that you install and use an up-to-date antivirus product. If you like, Windows 10 already has Windows Defender Antivirus included for antivirus. 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. The Malicious Software Removal Tool runs in quiet mode in the background. If it detects malicious software on your computer, the next time that you log on to your computer as a computer administrator, a balloon will appear in the notification area to make you aware of the detection.
