Malicious Software Removal Tool - Updates

MRT.exe is KB890830 6/11/2013 you either have it or you don't. If you don't their will be a new one next month.

Cheemag please put what anti virus and firewall you are using in your specs.

The MSRT is re-issued in a new version every month - which is why hiding it only works for a month.

It is purely an on-demand scanner - not a real-time scanner or preventive AV.

Just let it install/run every month.

I'll see if I can find that KB.

I have Bitdefender Internet Security 2013.

It comes up every 24 hours, not every month.

I think the best thing I can do is just to hit the [X] on the popup. That gets rid of it for a day.

If the MSRT is re-appearing that often, I doubt that it's running at all - which is cause for concern.
It could mean that the system is infected.

You should post in the Security/Malware removal forum and get your system checked thoroughly.

I'm pretty sure it isn't infected. MWB is run every few days and Vipre after any odd behaviour. Neither of them ever find anything.

I'll see what I can find in the Control Panel which may relate to this nuisance.

From what I been reading all you've done with the MSRT is either tried to hide it or delete it, you haven't tried to run it.

• Q27: How do I prevent this tool from being offered to me by using Windows Update or Automatic Updates?

A27: When you are first offered the Malicious Software Removal Tool through Windows Update or Automatic Updates, you can choose to decline downloading and running the tool by declining the EULA.

This decline can apply to just the current version of the tool or to both the current version of the tool and any future versions, depending on the options you choose.

If you have already accepted the EULA and if you would prefer not to install the tool through Windows Update, click to clear the check box that corresponds to the tool in the Windows Update UI.

It sounds like you have to run MSRT and when you get to the EULA, pick the options you want, clear the default acceptance of running MSRT and then OK/Yes to anything to back your way out to close the installation.

I'm not sure it goes that way because I've always ran it automatically, so you will need to watch what is being offered. It may even have the options at the bottom of the EULA with the accept/decline boxes outside the scrolling EULA window.

All is now clear to me after a bit of research.

This tool is a 'Tuesday' update which apparently will offer itself until it's been accepted.

It runs automatically once a month to look for some of the more common malware although a scan can be initiated at any time by typing 'MRT' into a command prompt.

I've accepted it, run it and we can now close this thread.

Thanks to all who responded.
