Generally, a download manager enables downloading of large files or multiples files in one session.Many web browsers, such as Internet Explorer 9, include a download manager.Stand-alone download managers also are available, including the Microsoft Download Manager.

if you do not have a download manager installed, and still want to download the file(s) you've chosen, please note:

You may not be able to download multiple files at the same time.In this case, you will have to download the files individually.(You would have the opportunity to download individual files on the "Thank you for downloading" page after completing your download.)
Files larger than 1 GB may take much longer to download and might not download correctly.
You might not be able to pause the active downloads or resume downloads that have failed.

MSRT targets prevalent malware families only. For comprehensive malware detection and removal, consider using Microsoft Safety Scanner.

Integration with automatic updates

Enable automatic updates to regularly get MSRT with Windows Update. The integrated version automatically runs in the background. If you would like to run MSRT on demand, run the standalone version.

Microsoft generally delivers MSRT with Windows Update the second Tuesday of the month. The standalone version available on this page is delivered at the same time.

Removal results and log file

After the standalone version of MSRT scans the computer and removes threats, it displays a report that lists the threats. It also generates the following log file:
