If you keep an eye on the updates Windows installs, you may notice the Microsoft Malicious Software Removal Tool appearing every month. It removes some malware programs, but only a few — it doesn’t replace the need for an antivirus.

'The Microsoft Malicious Software Removal Tool is an anti-malware utility that checks computers running Windows 10 Technical Preview. The Malicious Software Removal Tool actually predates Windows Defender as a product, and inmuchas Windows Defender only ships on Windows Vista, that leaves quite a few Windows XP and Windows Server 2003 systems that might not have Windows Defender installed. Microsoft Malicious Software Removal Tool is a simple and free utility designed to detect and eliminate malware from the PC. This program scans the system and search for malware presence. If it detects any nasty program, the tool attempts to remove it right away.

Microsoft’s malware removal tool exists as a sort of band-aid for the lack of antivirus in Windows. It attacks and removes prevalent malware, particularly worms, slowing their spread and preventing them from doing much more damage. It’s no substitute for an antivirus, which guards your system from a larger amount of threats, preventing them from taking root in the first place.

How the Microsoft Malware Removal Tool Works

Microsofe Malicious Removal Tool For Mac

On the second Tuesday of every month — Microsoft’s “patch Tuesday” — Microsoft releases a new version of the Microsoft malware removal tool. Windows Update downloads the updated tool, if you have it set to automatically install updates, and runs it in quick-scan mode. The tool quickly checks to see if a handful of common malware programs are running, and removes them if they are.

Its Purpose

This tool was created by Microsoft to help counteract fast-spreading malwareA Brief History Of The 5 Worst Computer Viruses Of All TimeA Brief History Of The 5 Worst Computer Viruses Of All TimeThe word 'virus' and its association with computers was affixed by American computer scientist Frederick Cohen who used it to describe 'a program that can 'infect' other programs by modifying them to include a possibly..Read More, such as the Blaster, Sasser and Mydoom worms, which infect a large amount of computers. Malware programs like these don’t only affect a single computer — each newly infected machine produces more traffic and infects other machines.

With the Microsoft malware removal tool, Microsoft can quickly remove prevalent strains of malware from a large number of computers at once, slowing the spread of particularly virulent malware. It mitigates the damage done by users who don’t run an up-to-date antivirus, but it doesn’t replace the need for an antivirus.

Limitations

The tool has extremely significant limitations. It:

  • Detects only malware that’s already infected your computer.
  • Removes only a few strains of malware.
  • Detects only malware running on your system.
  • Updates and scans your system only once per month.

Why You Still Need An Antivirus

Antivirus programs are the mirror image of the Microsoft Malware Removal Tool. They:

This perilous virus infection is able to do major damage to your PC. Best rootkit detection and removal. This noxious Trojan virus is a very harmful malware that is able to attack all version of Windows computer.

  • Prevent malware from running in the first place.
  • Try to detect every known malware program.
  • Scan your entire system for malware that may be hiding on your file system, but not actively running.
  • Run all the time, updating once per day — or more.

Running It Manually

While Microsoft’s malware removal tool usually runs in quiet mode, with no user intervention, you can also run it manually. Type “mrt” into the search box in the Start menu press Enter to run the mrt.exe file.

If the tool is more than 60 days old, it will prompt you to download a newer version. As you can see, Microsoft recommends running an antivirus product instead.

Click the “View a list of malicious software that this tool detects and removes” link and you’ll see a short list of malware. You can also view this list on Microsoft’s website.

From this window, you can do a full scan of the files on your computer instead of just doing the standard “quick scan.” To be honest, there’s not much value in running the full scan. If you’re going to do a full, in-depth scan, you should do it with a complete antivirus program. The full scan still only detects a few types of malware.

If you do a scan, you’ll hopefully see a message saying “No malicious software was detected.” As the tool only checks for a few types of malicious software, you can’t be sure that no malicious software is present on your system.

  1. Hi, if the MRT only runs once a month, can you tell me why it requires internet access frequently every day? Thanks.

  2. So, do you suggest using another anti-virus software other than MSE; if so, which one?

  3. I use Microsoft Security Essentials. Windows Defender is disabled on my system. I wonder if this is adequate or should I be running both?

  4. I think we cant rely on MSE as this antivirus is very basic.A person need to buy a good antivirus

  5. I think we cant rely on MSE as this antivirus is very basic.A person need to buy a good antivirus

  6. This is a smart blog. I mean it. You have so much knowledge about this information, and so much passion. You also know how to make people rally behind it, obviously from the responses. You've got a design here that not too flashy, but makes a statement as big as what you're saying. Great job, indeed.

  7. Avast is the best choice for me; tried avira, microsoft, avg, norman and few more.
    Avast was the only one able to detect bad web pages with malicious java scripts..so i even uninstalled kaspersky, because it couldn't detect bad web pages.

  8. I use Kaspersky on all 3 of our computers.

    • Bob - I would suggest you remove Kaspersky from every device and rebuild your OS from scratch. Russians have been stealing your data for 5 years now.

  9. I just have to comment on this article to show my love for Avast!
    Compared with AVG, avast! blows it out of the water. Even the free version is insanely effective. But for all of you who are fans of other antivirus programs, remember avast! offer the best free protection out there.

  10. I have been using MSSE for as long as it has been out. As a part-time PC technician I have installed it on many computers. It works fine and stays the heck out of the way. Price is exactly right.

    • I've had a lot of call-outs to fix computers that have had MSSE and ended up still getting compromised by viruses or malware. At one point, MSSE is about the worst in terms of detection rates. Most of the other free AV oroducts are better, especially Avira, AVG and Avast.

      • That's a load of crap! NONE of those free versions are any better, in fact I would say they are all lesser overall, than MSSE. You had best check your facts because you are WAY off base.

      • Actually Avira (scanned from HBCD USB) detected a Trojan that security essentials never found on my dad's computer.It could be a good idea to have more than one security program, one installed on your computer and one live CD or USB version that updates when you run it and then scans, something you can do when you'll be away (it took all night but that computer has an IDE hard drive and USB 1.1) for a while.

        I do like MSSE, though. In that it's light and 'stays the heck out of the way' like brentrjones says. Avast is another I like but people might find the alerts annoying and, at least last time I checked, you have to look through the options some to find how to disable them completely.

  11. I have used Avira Antivirus, Avast and AVG, but now I am using MSE and really like it! I recommend it to everyone too, specifically because it has an easy to use user interface.

  12. Norton has had pretty good ratings in recent years and I can get it free with my Comcast as my ISP .. so I use that. It has both av and firewall components.

    • @bb8ddda02d3a2083de79a065e6b2b43f:disqus If you're not advertising for Norton, then please stop recommending it. I don't want to say it sucks, but it sucks. Norton did a good job over 10 years ago, but their products went down hill starting with Norton Antivirus 2000 (yes, 10 years ago). If I were to recommend a security company, it would b e ESET and if I were to recommend an antivirus, it would be ESET NOD32. If you want free, go with AVG, but if you really care about your computer and personal information (name, address, online accounts, bank accounts, passwords) then you should fork your money to ESET or Kaspersky and forget about 'free' antivirus.

    • Norton is very thorough, but it's also very very slow compared to a lot of products, and quite a few other programs seem to conflict with it. If you switch to Eset, you'll never go back to Norton.

      • Pls update urself. Its not bloated now.
        I personally also like eset.

        • I agree. I fully support Free AV.
          But I am telling not to say wrong about something you don't have full details of.

          I never told anyone to try Norton. But I just wanted to tell that it is now one of the most fastest AV. Pls read independent online guides like Av-test and Av-comparatives.

          Again, Please dont think I am from Norton or something. :)
          I test a lot of AV fro my site, thats how I know this.

    • Norton admits that hackers got hold of their source code in 2006: http://www.cnet.com/news/symantec-says-source-code-stolen-in-2006-hack/

      I saw lots of computers compromised by the FBI Fakeware that were running NAV. In addition, I frequently had to remove customers NAV in SMWN because it was blocking all Internet traffic in normal mode.

      Microsoft Security Essentials? You may as well be running nothing. It has failed industry standard bench testing for some time now. I hear people say that they run it and have no problems. Yup. Until you run a different AV or malware software and show them all of the adware/spyware and malware the got through and is the reason the system is so very slow.

      But people will continue to defend it because it is free, it is from Microsoft and they argue that who better to patch Windows than Microsoft? Sounds logical except that the number of problems with Windows code has risen with each release. I would not trust an AV written by the company whose code made AV necessary in the first place.
