Microsoft is offering it's free anti-virus product, Microsoft Security Essentials (MSE) to 75,000 lucky people today.The company is offering the product via a beta program and will likely extend the cap of 75,000 downloads depending on demand. MSE is Microsoft's free anti-virus and anti-spyware product that is set to replace Microsoft's paid Windows Live OneCare subscription service which is being withdrawn a week today.
Earlier this month Neowin exclusively revealed MSE (codenamed Morro) and we believe that the final product will be available shortly before the Windows 7 launch in October.
MSE is being distributed on Microsoft's Connect site as a beta program. The build available on the connect site is 1.0.1407.00 compared to the 1.0.2140.0 build of the leaked copy. For more information please visit Microsoft's MSE site.

















You appear to be in a country or region where the Microsoft Security Essentials Beta is unavailable.
This beta is available only to customers in the United States, Israel (English only), People's Republic of China (Simplified Chinese only) and Brazil (Brazilian Portuguese only).
Booooo not fair
I hope it gets leaked so we can get our hands on it :-)
Thanks, this worked for me
Thanks! Works great!
Worked in Canada too.
Nice one, cheers.
Nice one, thanks!!

I live in Argentina and I was able to downloaded MSE Beta.

Interesting how one of the territories is the People's Republic of China.
I'm in the UK (Manchester to be precise) I've managed to download it from . . .
Microsoft Security Essentials on Microsoft Connect.
I'm not jumping on this one. will wait for it to get leaked on torrent sites
I was talking about 1.0.1407.00. I already have previous leaked copy installed
Since when did they EVER remove torrents?
I smell something fishy.
this beta is 1.0.1407.00
what the hell?!
The beta version is what was built and tested for public consumption, and it's what they'll be looking for the most feedback on. Using random leaked builds is a bad idea.
It is not the same.

I might switch if it turns out good.

According to reviews already posted it is one of the top three anti-virus engines available today. It is equally good as Avira and no annoying popups.

Will report feedback here, and to Microsoft of course!
haha i'm in East London too but if anyone catches me ever saying pukka then you have my permission to virtually slap me :p
not sure why the build number is lower though
Kudos.
Before i install are you switching off Defender, or Running Both?
Will Install now.
Very strange about the version numbers.
that sounds cool, i'd definately like to test that out!
No, yes. It has real-time protection and scheduled scans and you can turn either of them off and change the settings.
lol

Memory consumption :
MsMpEng.exe - 45MB
msseces.exe - 4.4MB
Boot I thing is the same, logging in to windows is faster since I switched from Trend to MSE.
Hope that helps you.
They are starting to show up on softpedia and fileforum.betanews already (XP/Vista/7 32/64-bit )

The funny thing is the current version of OSX is easier to crack than Vista due to a improperly implemented ASLR and the lack of other protections that make cracking Vista a hard chore for crackers. Just disregard Apple's claims on being superior to Windows in security because as Penn and Teller so eloquently put it, it is Bull S***.
Thats going to be true of with any anti-malware product. One will always catch something another didn't. A layered defense is always best
Thoughts?
Thoughts?
No, this isn't "more core OS", this is an app just like the others. Same usual "don't use more than one AV software" spiel applies.
Mine's running 1 process using about 5MB of memory, you must be smoking something.
Correction yours is running to processes.
MsMpEng.exe is the main process for MSE.

Oh really. I thought MsMpEng.exe was Windows Defender.
just wondering if any one have any info about it?
lol i do all the time, sounds to me the guys who created that app are a game fans =P
No.
Seems if you "Google" Microsoft Security Essentials 1.0.1407.00
Softpedia seem to still be hosting it. Available for Windows XP/Vista/7 in 32/64-bit
Fileforum Betanews is now redirecting to the "Sign in to Microsoft Connect"
I had no problem with it turning on anything of mine. Firewall still off, auto update was on already. Not sure why it would have turned your firewall on. I have installed on 4 machines with the same results on each one.
I am on Vista x64, but when it was downloading the update I turned off the AutoUpdate as it turned it on and the MSE's updater crashed. I'll try it for a few more days, but I think I'll stick with other applications.
Also, here's a surprise; the 64-bit version is *smaller* than the 32-bit version. (Even more surprising, it doesn't require a reboot post-install, which is not true of any of the competitors.)
Those of you griping that it turns on WU/MU (in particular, AutoUpdate) and the Windows Firewall: MSE uses WU/MU and AutoUpdate to fetch AV/AM/AS definitions. Also, why in the world would you turn the firewall (any software firewall) off? If you had another software firewall, I could understand it; however, why run without a software firewall at all? Windows' own firewall (XP SP2 and later) is actually a pretty solid firewall that takes up practically no resources; even back when I had just a gigabyte of system RAM, I noticed no performance dip due to the firewall being up. (Yes, my router includes an SPI firewall; however, having a software firewall up *behind* it definitely doesn't hurt, and, in fact, can only help.)
Because you're still on dial-up and don't want it downloading updates whenever it wants to?
the "new" version updates itself after install to the same build number as the leaked version 1.0.2140.0, so keep your version. The end result is exactly the same!
I'm seeing that in my Vista install, but not on XP
I'm impressed with what I see at the moment, but only time will tell to see how it fares up against what I'm using at the moment (AVG Free).
I think that I'll stick with Comodo for a little while longer.
Installed (replaced ESET Smart Security) and will give it a try.
That may change with the final version MS would need as much feedback as possible during the beta. So far so good as far as detection goes. If like me you do not have any virus files to test it with just go to Eicars it was able to detect and remove all the test virus on that sight.

So, no more downloads available to anybody.
Basically, yes. It turns off the built-in Defender and includes its own.

1. With real time protection and scanning turned off, my CPU usage would stay at %100. This started after several hours of MS Security Essentials was installed. It should be noted that this was a newly installed and fully patched XP pro on a P4 with 2Gbs of memory with no other AV or Firewall installed. The desktop would become fully unresponsive, and making it necessary to hard boot the system several times.
2. I uninstalled MS Security Essentials, but it BROKE Office 2007. I could no longer open any Word documents. Word refused to create or open an existing document, complaining that a security component had locked disabled opening the document.
3. I did a repair/reinstalled Office 2007, but initially it complained that a security component was denying the repair.
As I said, I know this is beta software, but when it starts to break other MS products would suggest that a great deal of Quality Assurance testing remains to be done.
