Microsoft Security Essentials Beta released

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anti-spyware product that is set to replace Microsoft's paid Windows Live OneCare subscription service which is being withdrawn a week today.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.

Bit of a slowdown but this could be Dreamweaver and or two other new apps. Will uninstall all to see if speed improves...

I've also had this a few times: Event ID 3002

Microsoft Antimalware Real-Time Protection feature has encountered an error and failed.
Feature: On Access
Error Code: 0x80004005
Error description: Unspecified error
Reason: The filter driver skipped scanning items and is in pass through mode. This may be due to low resource conditions.

this uses over 50MB of ram while kaspersky 2010 internet security uses maybe around 25MB so why would i want to install this over something lighter?

DONT INSTALL...I realize that Microsoft Security Essentials is Beta, but I had the following problems -
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.

Just because *you* had all those issues doesn't mean that everyone should stop using it. I have it on several machines, all with Office 2007, none of them are having issues at all.

I had similar problems just now actually. I set it to do a full-scan of my PC starting at 2am. I came into work at 8:30am and the disk was chugging away constantly. I looked at process monitor and it showed the anti-malware service was chewing its way through a 5GB ZIP file. I tried everything I could to kill it - even doing a hard reset as the PC was totally unresponsive. After restarting, it would just pick up where it left off.

No issues at all, and I've already tried it out in one of the labs here at the campus on some old Gateway computer that's maybe 4 years old...

I know you say you know its beta, but the QA that needs to be done is exactly why you're a beta tester.

I'm sure they're not supposed to be doing this, but Softpedia are actually hosting the installers for Security Essentials. Since they're a reputable site, I'd imagine I'm ok in posting this link to it, but I understand if this must be removed.

Just visited the site and

Is this going to replace Windows Defender???


Basically, yes. It turns off the built-in Defender and includes its own.

Ah! At the top of the page where they give the download link is a message:

So, no more downloads available to anybody.

Clicking on the http://go.microsoft.com/fwlink/?linkid=153446 link just gives me the following error message. By the way, I live in Ireland, so that might explain it.

I got the same message, and I am in the US. When I tried again, I got a link that says "Download Microsoft Security Essentials Beta", but when I click on it, I get another page that obviously is supposed to have the link to the actual file to download, but where the file link is supposed to be, it is blank.

Cool, this looks great. It's running really smoothly. I've just installed it one laptop, and I'm going to install it on my laptop in a minute.

Dumped it onto my Vista virtual machine and runs fantastic. Both the scan and update times were quick, and it doesn't drain much resources at all.

There's a simple and advanced option for that feedback. By default it is the simple opt in, which is minimal information it looks like to me.

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.

Yes I just noticed as well going through the settings that membership to SpyNet is not optional anymore. Default is basic membership and you can choose advanced. I don't really know what is send with basic membership as long as it helps to make protection better.

One change from Defender is you have to become a basic member of SpyNet to use this, and info is sent to MS from your PC. Not sure what to make of this...I'd prefer it be optional. Other than that, this seems like a winner.

I have tried both the "leaked" version and the beta release from Microsoft on my Win 7 (7260) system, and both versions hang at the "Welcome" screen after first reboot and force me to manually reboot back into safe mode to kill the service just to be able to boot into Windows.

I think that I'll stick with Comodo for a little while longer.

I'm using Windows 7 RC and I noticed, that I can't get pass Windows welcome screen, when my UAC is turned off. I have used safe mode to turn it back on.

I'm impressed with it, taking into consideration Microsoft's previous products and the facts that it's free and still in beta. I'm also happy that while it tells you uninstall other antivirus/antimalware programs, it doesn't conflict with them. While I want to use it, I don't want to depend exclusively on it, especially when I could use ESET Smart Security simultaneously.

Yes, I am going to try and run it with ESS NOD32 v4.x on Vista 64 and see if they two can co-habitate. This is on my main machine. Secondaries should be fine with this free beta alone. 8)

I'm in on the fun over here in the UK.
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 am running it with Avast at the same time without any problems.. I will remove Avast once I am confident that MSE can detect whatever Avast is able to detect

Anyone else seeing alot of security audit failures listed for MSE in their event logs? Running x64 version ontop Vista x64 SP2.

No, the only failures I see are that the firewall UI couldn't inform me of outside connections when my PC is logged off.

I'm seeing that in my Vista install, but not on XP

I try installing the beta 1.0.1407.00, told me the newer version is already installed 1.0.2140.0. I installed the leak version last week.

OgamaWab said,

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!

That is because MSE *includes* a modded version of Defender. For those of you that are wondering if you might have seen this program/application before, if you have Forefront Client Security installed, it's the same program. The server-side application is code-named "Stirling" and is also in beta. (However, Microsoft competitors in the AV/AM/AS business still have no room to complain, as all of them did the same thing with their own basic software that MSE/FCS competes with; only Avast!, AVG, and Vipre don't charge for the basic version, and of the three, only Avast! Home scores close to MSE/FCS in terms of protection, and Avast! Home is a bigger application.)

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.)

I have my firewall turned off because my router has the firewall. Never ever had an issue with this and never been burned by it. Besides my wireless printers like the software firewall turned off for some reason.

joemailey said,
I agree. Again I don't know why you would turn of WU/MU lol

Because you're still on dial-up and don't want it downloading updates whenever it wants to?

According to the support forum, even if you have WU on "Never check for updates," MSE will still update itself. So there's really no reason for it to put WU on Automatic. At the very least, it should ask the user if it sees that it's already off.

UK here, just downloaded. First scan was very quick! Looks nice and runs with few resources. Very impressed so far!

Softpedia seem to still be hosting it. Available for Windows XP/Vista/7 in 32/64-bit

for me it seems like a replacement of windows defender or a new version, in fact it overwrite or unistall defender to put this one, im running nod32 along with this on a pentium II 1ghz and 512ram seems run very fine.

Chrono951 said,
Everytime someone mentioned Nod32, I think of the Brotherhood of Nod. Anyone else think of that?

lol i do all the time, sounds to me the guys who created that app are a game fans =P

guys, I am just wondering what is the license to use the free edition? is it for home use only?

just wondering if any one have any info about it?

Looks like it's their corporate anti-malware product, Forefront Client Security, with a stripped down front end. I've run that before, and it's a pig for CPU resources. Watch the MsMpEng.exe process when installing software and see if it uses 50% CPU time in Task Manager. I hope they fixed that, but I doubt it.

JHH said,
Too resource heavy. My ESS uses like half of it.

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.

joemailey said,

Oh really. I thought MsMpEng.exe was Windows Defender.

It's working really well so far. I'm not sure about the detection and removal rate though. But some people are claiming it was able to find some malware that others could not, so that's promising.

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

Speaking of layered defense, has anyone tried running this IN ADDITION to something like NOD32 or KAV? Normally, that would be a HUGE no-no, but since this is more core OS, I'm wondering if this makes any sense whatsoever.

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.

This should be bundled with Windows 7!! Then maybe Apple would stop whining that Windows isn't secure!

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***.

They are starting to show up on softpedia and fileforum.betanews already (XP/Vista/7 32/64-bit )

Beta Microsoft Security Essentials 1.0.1407.00 (Digital Signature is Tuesday, June 16, 2009 4:37:58 PM)
Size for Windows Vista/7: 4.72 MB (4,958,768 bytes)
Size for Windows XP: 7.51 MB (7,876,240 bytes)

Works for me, I am in Australia. If you select download single file only option IE wont use the download manager.

what's your memory consumption? and is there a increase or decrease in your boot time compared to the other antivirus you had before?

Windows 7
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.

Is it one of those anti-virus things that MUST run in the background? Or can I configure it to only run and scan whenever I want?

Udedenkz said,

No, yes. It has real-time protection and scheduled scans and you can turn either of them off and change the settings.

Keeping viruses on your external sounds kinda awesome. Like you are running some sort of computer prison, or you are an evil hacker.

did you modify the viruses so that they lead "nowhere" (nobody on the other side)?

that sounds cool, i'd definately like to test that out!

Servers seem to be getting hammered? No way there is this much demand. I keep getting Internal Error. Oh well, it's a good sign, I guess. Have to try later.

The leaked version on Win7 turned off Defender, so no need to interfere manually as I see it. Leaked version has been running solid here for about 4-5 days, but guess I will remove it, and install the official beta, still pondering about the version numbers myself.

It should automatically set everything up, I would think. But yea, Defender's disabled, but Windows Firewall MUST be enabled, unless you're using a different 3rd party firewall.

Got it and it's good. Running at work on a dc5800s (Core 2 Duo E8400 @ 3ghz, 2gb, vista x86 sp2) and it's averaging at about 50-60mb of RAM and 20-30% cpu usage. I just saw it at it's highest (full scan) at 74mb and 50% cpu. The numbers might seem high but i don't feel a difference in performance and i'm doing like 10 things at once.

the beta version is newer as the digital signature is 3 days newer than the leaked version

not sure why the build number is lower though

Thanks McDave and WillDev. I am in the UK but have already registered with Connect just now, downloaded MSE, installed, and it is already on it's first scan! Pukka, as we say here in East London........
Will report feedback here, and to Microsoft of course!

BavonWW said,
Pukka, as we say here in East London...

haha i'm in East London too but if anyone catches me ever saying pukka then you have my permission to virtually slap me

Steps to get it:
1. Click on link
2. Log into connect
3. Take survey
4. Select version (Xp 32 bit, Vista/7 32 bit, or Vista/7 64bit)
5. Download the download manager
6. Wait
7. Run the installer

I switched from Avira free to MSE. Both have low resource usage, but MSE doesn't pop anything up unless something's wrong.

Recon415 said,
Waiting until I can see how this compares to Avira.

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.

Link?

A higher version number doesn't always mean it's "newer" or even "better." Especially for a pre-release / leaked build.

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.

When its free , why not give it to everyone? This is silly... I struggled to get Windows 7 beta key later to find out it was same bunch of keys which was given to everyone .

I'm not jumping on this one. will wait for it to get leaked on torrent sites

. . .not only is it already on torrent sites it has been for almost a week. Seems as though their are a few individuals who aren't keeping up with Neowin News.

I was talking about 1.0.1407.00. I already have previous leaked copy installed :P

Its funny, when i click on Get it Now! it bring the connect page telling me that the invitation is for another registered member. But strange enough i was able to add it to my connect control panel earlier today but there is still no detail or download link on it

Yeah, I get the same thing. I even tried another Live ID and it's invalid as well. Guess someone screwed up or they're overwhelmed.

If you have region issues, change your current region settings that are associated with your Live account to US or any of the other supported countries and attempt to download it.
