Download Free Microsoft Security Essentials – Kill Malware DEAD!

image Microsoft Security Essentials, which incorporates antivirus, antispyware and rootkit protection, all under one roof, was released by Microsoft as a free  replacement application for the late, and unlamented, Windows Live OneCare.

I’ve been running Security Essentials for eight months, or so; first, as a beta tester, and now the final product, on my Win 7 machines. Backed up, of course, by my usual, on demand security applications, including Malwarebytes’ Anti-Malware and SUPERAntiSpyware.

Testing this application under real world conditions, has reinforced my initial positive review of Microsoft Security Essentials.

So, I’ll just cut to the chase here:

Microsoft Security Essentials is a no cost viable alternative to overhyped, and often overpriced, more familiar security applications.

A simple, intuitive, and easy to use interface makes Microsoft Security Essentials straightforward to setup, customize, and run, for both less experienced and expert users alike.

Microsoft Security Essentials is a first class security application; fast, efficient, and effective.

Provides full real time protection against viruses, spyware, and other malicious software. Very few “free” security applications, provide full real time protection which makes such an application valuable, only as an on-demand secondary scanner.

A simple command interface:

MS Security Essentials

A simple settings/options screen:

MS Security Essentials 2

A simple scan result screen – in this case a “clean” result:

MS Security Essentials 3

Or, a potential threat warning screen – following an injection, in this case, of a malware file:


Fast facts:

Easy to set up and run, particularly for new users.

The interface is positively simple offering Quick Scan, Full Scan, or Custom Scan.

Scans all drives including removable drives, and creates a system restore point

Full real time protection against viruses, spyware, and other malicious software.

The Dynamic Signature Service (DSS), a technology that helps ensure users are protected by the most current virus definitions available, without having to wait for the next scheduled download, is a major positive step for the average user.

Using DSS, Security Essentials validates suspicious files in near real time – a huge advantage for average users.

Actions from unknown sources such as unexpected network connections, attempts to modify privileged parts of the system or the downloading of known malware, all trigger requests for updates from DSS – another major advantage for the average user.

Runs unobtrusively in the background with an easy to understand warning system. Green – you’re good to go. Yellow – caution. Red – action required.

Very lightweight in terms of system resource usage – as opposed to some security applications that are well known resource hogs.

Malware identification and removal, in my experience, has been much better than average in real time extended testing, and not just in a 30 minute wonder test!

Quick scans are very fast, but full scans are slightly slower than average. However, if I’m infected, fast or slow is not a personal consideration – detection and removal of malware is.

System requirements: Windows XP, Vista, Vista x 64, Win  7, Win 7 x64

Microsoft Security Essentials is a first class security application; fast, efficient, and effective. I highly recommend that you take a close look at this program.

    This is one fine program so far. I’ve been using for a couple of months. It works and is simple to use.

      Hey Greg,

      You’re right it is “simple to use”. In fact, when I first installed it, it was so simple that I kept thinking – I must be missing something. I kept looking for the complexities, but there just weren’t any.

    Hey Bill,

    Thanks for the review on this, I’ve often wondered whether giving this product a go was worth it, considering Microsoft is so lacking in other areas of security. I see a positive in this, that they are developing products which are effective.

      Hey Mal,

      I think MS finally got their act together with this one. It’s a pretty solid performer and worth a try – but only if you’re unhappy with your existing AV.

    Microsoft Security Essentials is my main security app on my PC. So far, I have been very pleased. Very easy to use and understand for the everyday user. Great writeup on this!

      Hey Rick,

      That’s the great thing about Security Essentials – it’s so easy to use.

      BTW, spent over 12 hours in the Hospital yesterday Two MRIs, and one CatScan later, the diagnosis was straight to the point – without surgery I run a substantial risk of losing mobility in my legs. I’m now scheduled for back surgery in the next few weeks. I’ll know more on Wednesday.

      I knew something was really wrong when Percocets didn’t reduce the pain – not even a tiny bit. I’m now on Morphine (if you can imagine), and even this barely reduces the pain. It brings it down to a manageable level only, so that *Amitryiline*, which is mainly used as an antidepressant, allows me to get some sleep.

      Too much time at a keyboard, plus poor posture, has something to do with all this, I think.

      Talk to ya later,


  4. The two senior (more than me) citizens that I support are using MSE but, unless they click on something bad (and I’ve trained them not to) it’s hard to know how well an anti-virus or anti-malware solution is performing. So thank you for the reassuring post! 🙂

      Hey Dave,

      You’re right – it is difficult to gauge the effectiveness of an AV. In most cases, a user is guided by tech reviews. Unfortunately, many reviewers don’t test in a “real world” environment, which makes the review worthless, in my opinion.

      Good job in training your seniors not to click haphazardly. Much more difficult to do than most people realize.

    Hi there Bill

    Clearly Microsoft have a good program here. However, please warn your faithful followers that they should NOT download it alongside other anti-malware and anti-virus programs. Mr Microsoft does highlight this fact prior to installation and requests that all similar programs are uninstalled first.

    Love, Light and Peace

  6. Bill,
    I agree, this is now my favorite free AV product. I’ve used AVG, Avast, and Avira and Security Essentials trumps them all. I also noticed Maximum PC mag. gave them a high rating in their recent tests. It still lagged Eset’s $60 a year suite but you can’t beat the price.

    Hi Bill,
    I use COSAMIN D for my back! It cured my 2 ruptured (crushed) disc. Were bone to bone! now xrays show no sign of a problem! I highly recomment you checking this out. It is at Costco. Drug Stores have it at twice the price!
    I hate surgery! Lots of times there are other alternatives! Best of luck.

    I sure hope you are doing Ok with your Back and all… As Roy mentioned, look at all of the alternative; which I know you have…
