Microsoft Malicious Software Removal Tool checks your computer for infection by specific, prevalent malicious software (including Blaster, Sasser, and Mydoom) and helps to remove the infection if it is found.

This tool will help to remove specific, prevalent malicious software from infected systems. Because computers can appear to function normally when infected, Microsoft advises you to run this tool even if your computer seems to be fine. In addition to using this tool, you should use an up-to-date antivirus product to help protect your computer from other malicious software.

    MRT is a tool which runs "Once a month" During Win Updates. Otherwise, It lays dormant unless it is "called Up". It is a useful tool "ONLY" If your system has ground to a halt. (Do Not) rely on MRT/MSERT alone.

    You need
    (1) A "good" A/v which is Highly configurable.
    (2) A "second opinion" like M/ware-Bytes for Instance.
    (3) A Nifty tool to keep at hand, TDSSKiller.

    - Launch TDSSK: Allow "updates" & then go into (change parameters). Some Items are ticked by default. Also TICK (Detect TDLFS file system).
    You "MAY" get a suprise in some cases..!!

    Your A/v should be running at all times. Other tools should be used in conjunction with your A/v, but only on a "call-Up" basis. Too many tools monitoring your system in "Real Time" = False positives, & Crashes.
    Still 3* for being an Alternative (Tool)..... "Keep Safe" .. ^_^

    Download & run MSERT as an alternative to MRT, Or at least give it a try.. lol

    Follow this link & Directly below the Big Blue "Download Now" Button.
    ("Select your Version" link). Click = (32bit - 64bit). Note 10day Expiry.
    Usually between 70Mb-90Mb, Portable, Fairly quick scan. Double click & run
    from wherever you selected to download. Same UI as if you called up MRT.
    Not the best by any imagination, It'll sniff a "Rootkit" among other Bogeys.

    The usual 3* for being an Alternative.

    As I already use some pretty decent anti-malware this has never found anything amiss on any of my PC's - If you take the time to read the terms & conditions it's probably of more use to MS to have a bit of a snoop around your PC as anything, I can live with that though & seems harmless enough to me.

    BTW although I don't use MSE the detection rates are now pretty good.

    Anyway, installing latest version before patch Tuesday like today prevents updates from not only installing it, bun running it, saving an extra 10 minutes or so, for those patching on-line. The application is always served minutes before the patch is released: eat well :)

    They often issue this to remove rootkits or other malware that is otherwise very difficult to detect and remove. Rootkits, after all, can hide from any security software while the OS is booted. I applaud Microsoft's introduction into the security market with this and MSE. This tool basically will take care of any essential threat that need be pushed out due to the infection rate, or implications.

    This is a scam not made by Windows. It is a part of the Fake Microsoft Security Essentials. I know that this is a scam because earlier, my computer was infected by a scam called "Palladium Pro" which was a part of the Fake Microsoft Security Essentials. That program wouldn't let me get anywhere! I never asked for an installation of "Microsoft Windows Malicious Software Removal Tool" it just came to my computer! I never clicked "Allow program" because I know it is a scam! A virus! In my opinion which is probably correct, the people who made the "Microsoft Windows Malicious Software Removal Tool" wrote the review to trick you! This is a truth, so please don't install this! Don't allow it! If you did, go here!

    yeh not sure how this got a 5 star in voting, considering Windows hassles you until you install some kind of anti-virus kit to deal with what the Malicious Software Removal Tool is meant to also address? Waste of time. I'm only writing because I DID NOT download this tool, yet 6 mysteriously named directories appeared in my system, all containing this exe! Now, I wonder, how did that happen? I'm sure I never consented to unsolicited software downloads even if it is from MS, but I was sceptical before running it until my own anti-virus/mal-ware took a look at it. Utter waste of time: We need minus star ratings.

    I would have to say this is another typical poorly thought out product by some navel-gazing geeks in Redmond and whatever benefits there might be are not worth the hassle.

    After 3 days of scanning my PC (without letting me select or even know what parts of the PC were going to be scanned), my only option was a checkbox saying 'Heal' and a 'Continue' button. Clicking that button prompted me with a warning that files might be harmed by this process and continuing THAT immediately started a process with again, zero feedback other than the squirrels were running on my machine.

    Any other commercial grade software you use for virus checking etc will at least show you what files were infected by what. What kind of moron thinks up this type of user experience? At least there should be a 'find out what was infected' selection.

    The irony of it is that after clicking the 'cancel' button on the 'healing process, the 'Healing in process' dialog box is still onscreen and you're locked in a loop of 'cancel' - 'are you sure'? Gotta use Task Manager to kill it.

    Linux and Apple are going to continue to eat MS' lunch !

    As a hands off tool works great, doesn't
    find problems that I don't have: That is,
    My box is free of malicious software that
    I don't want, it agrees and doesn't scream
    that the cookie that autologs me in to my
    home page is a security threat that will
    kill me and my credit rating and my little
    dog Toto.
    As a hands on tool, one huge flaw.
    On this laptop which is running on the
    mains (Battery is over yonder) I plugged
    in all of my USB storage and told it to
    scan everything.
    It seems to scan the system in alphabetic
    order (c and d are the permanent drives)
    and for the first about three days didn't
    report problems.
    Last night it reported finding six threats,
    and now after about six days it is done
    and shows four bad things found.
    It doesn't say where, But I assume that
    it is in
    where I go ctrl+a, a. (Forte Agent command:
    select all, save files in selected posts.)

    It's not saying where the problem is? Huge
    flaw for the types of people who play with
    beta s'ware.
    A five for not saying harmless is harmful,
    a finger for not saying _which_ files it thinks

    More info here
    The installer that you get from here or manually from Microsoft starts in a interactive mode. The tool' when activated in interactive mode allows you to choose
    Performing a full 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 will not be scanned.

    How the MMSRT differs from an antivirus product

    The Microsoft Malicious Software Removal Tool does not replace an antivirus product. It is strictly a post-infection removal tool. Therefore, we strongly recommend that you install and use an up-to-date antivirus product.

    The Microsoft Malicious Software Removal Tool differs from an antivirus product in three key ways:
    • 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.

    There are probably more PC's out there running without any antivirus on them than there with AV, and even on the ones that do have AV there are still a huge number of those that never get updated.

    People are rating this bad just because it doesn't run on pirated copies of Windows? Yeah, and Corvettes suck because I keep getting thrown in jail after I steal one. Gimme a break.

    Like McAfee's Stinger, this little utility doesn't attempt to catch thousands of malware programs, only the most common and serious. Unlike McAfee's Stinger, this tool isn't biased towards just viruses; all types of malware are handled equally. Early versions were simply a crutch for users who were unwilling to use real antimalware, but recent versions have been capable of removing some of the most sophisticated rootkit-protected threats.

    Although Microsoft's tool is packaged similar to a hotfix and therefore "looks" like it is installing, it doesn't really install anything except a registry entry (to prevent Windows Updates and Automatic Updates from repeatedly downloading the same version). It simply runs, cleans whatever it finds, then exits. Nothing remains running (which also means that you don't get any ongoing protection).

    My windows got corrupted because of this tool. I run the windows update at background. After the updates were downloaded and installed. System prompts for restart. But nightmare came after I restart the pc, I can't boot into windows, there a blue screen being shown and automatically restart. This process repeat again and again. The only solution I found was reinstall windows for 2 times. The first time my windows being corrupted, I thought was caused by installation of Visual Web Developer Express. Finally I found that the problem was caused by the Malicious Software Remover tool. So becareful when apply Windows Update, don't let it run at background, at least let it prompt for install after download. It better to check the list of windows updates. I am not anti Microsoft. In fact, I like to use Microsoft products except this Malicious Software Remover Tool.

This tool is quick and should be run after the Firewalls are turned up and before any other program on a newly touched system.

    The tool works and does its job the guy hd that he said corupted could had a virus attached to the files on that drive and the tool was just trying to do its job. Just cause you run all kinds of av or anti spyware stuff does not mean you dont have a virus. I have played with virus's myself to just see wat it takes to make them undetected by av usualy just rename or edit the virus with a hex editor or programing tools and its no longer a virus. Av wont detect it anymore because you just made a new type virus even tho its still the same just small change.

    I have an WD 120gb External Hard Drive, which I store my graphic files on(about 30gb worth). I have several adware and spyware programs and Virus Protection and Firewall and they never showed any bad stuff on this drive. I installed the MS program as it was on the Windows Update Site when it first appeared in January. It totally corrupted the drive and I lost all 30gb's of graphic files and projects. XP restore could not do anything. Luckly WD had a tool that enabled me to recover most of it. I still lost the most recent files I had worked on and edited earlier that day. So be forwarned,DO NOT INSTALL THIS PROGRAM,it destroys without notifying first or gives options like quartine first. There is plenty of other good freeware that does the same job without any problems.

    Creates more problems than it solves. I already have anti-virus software but I ran this anyway. I thought, "what can it hurt?" The one thing that had me worried a little before I used is that it says that it will automatically remove the infections. Thinking of how microsoft often has bugs in it's software I was thinking that it might automatically remove other files that are not infectious by mistake. I wish I was wrong about that but unfortunately not. After running it didn't find anything. Later in the day I tried to install software but they were all aborted due to "16 bit Windows Subystem - Data error (cyclic redundancy check) :\windows\system32\"

    It had removed my autoexec.nt file

    I gather the intention of this tool is to be downloaded automatically by Windows Updates and check your computer for the most common viruses in the background. Then if it finds any alert the user and guide them through its removal. This will no doubt be updated every time a new big virus hits.

    This tool only really has use therefore for those who don't run antivirus software. Also useful for system repairers like myself who might only want to do a quick basic antivirus scan over a computer without waiting hours from antivirus software.

    Does what it is suppose to. I don't know why people expect these virus removal programs to detect "everything" because no program like that exists. The vast majority of the signatures of every single AV vendor only detect malware, and do not remove them for you beyond deleting the files, or simple file cleaning. It is indeed a good step, perhaps the only thing Microsoft can offer for free without breaking anti-trust laws.

    Make no mistake, this tool is meant to supplement your AntiVirus software, not replace it.

    It doesn't install itself, it simply executes and then exits on completion. It is currently available via Windows Update for WinXP users.

    The benefit of this is obvious. A massive percentage of virus infection occurs on home users that don't have a clue and/or don't have AV software (or don't update it or run it regularly). A large portion of these users will be using WinXP. Once a month, when these people run WindowsUpdate (hopefully they at least do that!) the Microsoft Malicious Software Removal Tool will run on their system and detect and remove the more common viruses.
