Shadow Defender is an easy-to-use security solution (for Windows operating systems) that protects your PC/laptop real environment against malicious activities and unwanted changes. Shadow Defender can run your system in a virtual environment called 'Shadow Mode'. 'Shadow Mode' redirects each system change to a virtual environment with no change to your real environment.

If you experience malicious activities and/or unwanted changes, perform a reboot to restore your system back to its original state, as if nothing happened.

If you are x64 OS user, please get the installation materials here (file size: 10.6 MB)

Thank you for voting!
Please add a comment explaining the reason behind your vote.

#93, Whiterabbit-uk: you never mentioned if you rebooted the PC after installation... If you did not reboot then the program will not work or properly execute any of its component parts even if you try to do it manally.

Assuming the 64-bit build is 64-bit executables as well as driver, then it should be (assuming standard drive lettering) in:

C:\Program Files\Shadow Defender\

If only the driver is 64-bit and the executables are 32-bit then they will be in the x86 version of the Program Files folder.

On reboot if the installation was successfull, you should have a new tray icon that you can use to lauch the GUI or hide the icon with.

This program has the same concept as freeware Microsoft Windows SteadyState.

Microsoft discontinued SteadyState in 2010. The latest was v2.5 for Vista SP1.

With Win7+ we can do it using Windows internal features. See "Creating a Steady State by Using Microsoft Technologies".

This is probably a little too late to get any response (less than 30 minutes to go before the end of the giveaway). Despite Fubars comment I decided to install today's giveaway, but cannot find a shortcut or the installed program. (my O.S. is Win 8) When I try to search for Shadow Defender it says there's no app with that name (or words to the effect). I didn't make a note of where it was installed, so tried to install it again (and again). It goes through the installation process, but there's no path displayed. Has anyone else had this problem and was it solvable? Thanks in advance for any help.

p.s. I've looked through processes (via Task Manager) to see if its running, but cannot find it. Also I'm on a 64 bit system and did install the 64 bit version. :)

@Fubar -

Fubar - I have a very fuzzy recollection that perhaps you used to use ShadowDefender, no?? My memory of your mentioning it is vague, but I'm sure I remember you thinking highly of some kind of "light virtualization" product. Wasn't Returnil, wasn't RollbackRx or TimeFreeze...

Did you used to use this at one time and think highly of it or am I thinking of something else?? If it was ShadowDefender, why the apparent change in opinion?

Also... anyone had any experience in using this along with RollbackRx??

BTW this build distributed by GAOTD is pre-registered, there is no visible sign that it is registered apart from the lack of trial nag alert box that the trial build pops up on lauch of the GUI and a REGISTER button on upper right of the GUI. Both of which we never see.

I would have liked to have an optional scratchpad path assignment where the virtual write cache can be assigned to a drive letter and be saved like the paging file is rather than leaving it only in RAM... after all RAM is limited even when virtualised, RAM is limted especially on a 32bit OS... I would like to have been able to assign the write cache to my 5Gig Ramdrive and overflow to a physical drive letter and leave the physical and Virtual RAM mapped into the sub 3Gig region for its normal uses.

Oh just been playing with it in a VM and it apears I was hastey in my statement that it lets us enter and exit shadow mode without having to reboot... While it technically does do that, there are scenarios where changes are made to files in shadow mode that are not closed while windows is running and so cannot be updated to commit or discard changes while the windows session persists and so requires a reboot to release the files so they can be reverted or updated. Oh well, geuss we can't have everything... yet.

Reply   |   Comment by TK  –  10 years ago  –  Did you find this comment useful? yes | no (0)

It's not mentioned in the GAOTD system requirements but in the 32bit instalation there apears to be a windows2000 driver and the help file which is a little aged... circa 2008 does list windows 2000 professional as a supported Operating System.

I like the fact that this does not demand one restart the PC to enter or exit shadow mode or to commit shadowed data to the physical drive.

It also happily installs inside an MS virtual PC 2007 virtual machine.

I shall be keeping it as it does seem to be well thought out and as long as the shim driver they insert into the disk drives driver chain does not introduce instability it should be fine.

I agree wholheartedly with Fubars warnings on over-reliance on the claimed invulnerability to rootkits and other malware that is made for this type of software and that it offers no imediate realtime protection within the current session and infections can happen and data be snooped and system resources hijacked for the duration of the current session.

I do think this type of software does have its place and purpose but the protection from malware is not really it's purpose, more protection from medling kids in a youthclub or returning PC's to a controlled clean state on each days start at some educational orgonaisation or similar corporate venu where users must be able to start a machine in a known configuration regardless of what was done yesterday, and users are forbidden from storing personaly data on the physical machine or customising the GUI in anyway.

How do you shut down Shadow Defender and exit the application? Once it is started up, there is no way I've found to kill the application unless you go to the Task Manager.

Bon Giovanni - answer to your question - Why COMODO INTERNET SECURITY is free.

COMODO is in the Trust and Authentication business and not the anti-virus business. They do T & A stuff for the big banks and merchants.

When Obama ran his first presidential campaign his team used COMODO to do the T & A for his fund raising. Remember his angle was to obtain his funding from the "people" and not the corporate donors. His website collected about half a billion dollars.

When an Obama follower went to the fund raising site to make his or her contribution the question is, "Am I on the right site or a scam site?. This is where the T & A plays its part. Obama did not want his funds to go to some scam artist with a look alike site with a similar sounding domain name.

The T & A business allows COMODO to charge the mega banks mega bucks for their service. A sweet big monthly fee per bank or merchant.

This means that COMODO does not have to sell 20k copies a month of their antivirus product to survive. This is why you never see them compete in this niche. (The compete in the T & A niche).

To be in the T & A game they need to be totally on top of the anti-virus game. That is why their AV product is so damn good.

CIS is like their loss leader - promo leaflet. This means they do not have the pressure the AV companies have.

There are some regulars here whose opinions I normally respect however one of them is very wrong IMO today (I won't mention names) because this program is a simple, excellent tool and used as intended is very very safe and will totally save your computer if you are venturing into danger zones whether on the Internet or installing an unknown program or trying out something that might have potential to mess up your Windows. Then and only then you turn on Shadow Defender. It's not something you would leave on all the time unless it's a kids computer that you want to always boot back up the same way. You can still save info to a flash drive also. To answer one person's question yes you have the option to have it start up or not with Windows. It's one of MY top ten most valued programs.

Thanks to #67, Saved my day, In my opinion, From everyones opinion here A waste of time, GOTO Used to have some really great software that I still use, Is it that the developers have ran out of new ideas, Or is it the new thing to try and improve someone else's idea, If I have to go back to school to use a new piece of software I don't think I need it, Like # 67. sorry, I had that happen to me a few months ago, from a giveaway. It would be a great piece for Libraries and schools. Since I have neither I will pass and will still be able to use my PC again tomorrow.

I prefer to make a backup of Windows the day before the updates are released the 2nd tuesday every month by Microsoft. I use a bootable disc with the backup software and let it backup the entire partition to an external drive. I do this for all my Windows computers.

Experimenting with software i don't seem to understand is a big no, even if i have used Windows for many years now.

Too many here seem to have problem with the setup also.

I already have other security software installed that i trust about 99%, so i don't need this one. Sorry. But thanks anyway !

@16 Giovanni - nice job learning about software that's been around for years. I have been using this suite (currently called Comodo Internet Security Premium, but it still is free) for around 3 years and I'm not a fan of trying every new program just because it's free, in particular when it comes to security software.

I installed shadow defender on xp 32 bit.
works fine.for those of you worried about anti-virus update or windows
update dont worry because shadow defender can be turned off easy
for updates to take place in your real computer.then just turn sd
back on anytime.
to turn shadow defender on or off just go into the settings
mode setting, then click enter shadow mode or exit shadow mode.
when you click exit shadow mode you will be in your real computer again.

Windows 7 user here -- the problem i have with protecting files from rollback is that I don't know where all those files are, or often, even what they are named (control files, especially).

Some are in the folder with the application creating them. Some are in Libraries. Application Data, Users, various system files ... Even when I know their names, "search" may turn up none, or dozens with the same name in different paths.

Yes, I grab file utilities when they are offered here! :-)

#21: "... there are certain things you DO want to save – like your AV definitions – and certain things you DON’T want to save, like your browser cache..."

Sorry but I have to disagree... This is a very real problem when you for example restore an ERUNT registry backup that's more than a few minutes old -- AV apps can store their state in several files & in the registry, & if that stuff doesn't match, it can break your AV software so it will not update. And, some updates include just definition files, others *also include* updates to the AV app's working files, which may or may not be stored in the same folder you excluded from protection -- mismatches there can cause problems. You could unprotect everything having to do with your AV software, but AV software can be the 1st thing malware attacks -- it tries to disable AV software so it's dirty work goes undetected.

#30: "If I suspect that a program might have a virus then can I safely run the program using Shadow Defender?"

That's one reason why you'd use it

"Can you tell Shadow Defender to protect certain programs or do you have to tell it about every program on the drive your protecting which could take a while?"

You turn protection on/off for different areas of your drive/partition -- do bear in mind however that if your goal is increased security, there is no standard folder where all malware adds all its files. :) If you unprotect My Documents so you can save your Word files there, malware can put its files in My Documents as well. That may still not be a huge problem because something has to run malware files, or just like any software you're not using, it just sits there where hopefully an AV scan will find it.

* * *

#35: "How does an anti-virus software works when Shadow Defender is running? Does the anti-virus software still runs without causing problem to your PC?"

Assuming SD or whatever virtualization app is working properly, everything works normally -- you &/or your software [including Windows] shouldn't notice anything different at all. It's like running software like a game from a CD/DVD -- nothing can write to that disc so every time you shut it down everything's exactly like it was before. Nothing can actually write to the protected drive/partition, unless you allow it, so once you restart everything's just like it was.

The moderators held my comments #7 & 9 while the rest of you were going gaga. I understand that vendors need customers, but they allow comments from others like Giovanni. If you use software like this, you will lose data no matter what exclusions you list. In the first place, you have no idea of all of the locations that Windows and programs use. In the second place, the Registry that you love to bad-mouth is where many settings are stored, and are you going to exclude that? I don't know about the rest of you, but my computer actually does things and I actually use it. These types of "solutions" are long-obsolete, much better solutions are available, and this type of software is far more trouble than it's worth. A very few "big-name" vendors still provide this type of software, but most have long since dropped these types of utilities, including Microsoft.

Dear GOTD team. Like always some of the visitors are not able to read all the information properly. Therefore they are stumbling with the installation on x64 OS.

BUT even if the x64 setup is downloaded from the given link, on Win 8 Pro x64 there is a bug: the installation stucks on the extracting process with 0%. Cancel fails, so it has to be shut down with the TaskManager, which shows a "7z Setup SFX (32 Bit)" application running. The previously here given away excellent Soft Organizer 3.04 shows over 56000 traces for a not finally installed prog! So PLEASE could you fix this annoying bug. I was losing hours with the problem. Many thanks in advance.

#36: "I’m curious about things like automatic updates, for example Microsoft’s automatic update in the middle of the night. Normally after an update it automatically restarts the PC. Won’t updates like that be lost? Also Malware bites updates regularly. There are several other software’s that update regularly. Well, you get the idea. I looked at the site and it appears that we can exempt some things, but how do I know what to exempt, and if I do am I negating the benefit of Defender?"

You have to set a new baseline from time to time whether you're always using a virtualization app or when you use a VM that you frequently restore, because you're right, those changes won't be permanent otherwise. With AV software it's not usually a big deal to update as soon as you reboot, or if using a VM, when you start it after restoring a baseline copy, but that won't work when the update requires a restart, & you're not protected with the latest security during Windows startup. Since lots of AV software updates several times during the day, often without notice, it wouldn't be practical to try & turn whatever virtualization app off, update the AV software again, then turn it back on, so I don't know there's any help for it. You probably wouldn't want to exclude any part of Windows [including the registry] from protection, nor your AV software, since those are the targets of most malware in the 1st place.

I think in the end everyone just has to do their own cost/benefit analysis -- is the extra hassle worth the extra protection? If you read the reviews & tests of AV software apps, nothing catches everything 100% of the time, so adding another layer helps. But OTOH you have a PC/laptop to use it -- not to spend all your time & effort trying to protect it -- so when does that time & effort become too excessive?

Just FWIW... My kids are grown, but if I had one or more that was prone to careless PC habits I imagine I'd isolate their systems from the rest of the home network, then likely make them use a Windows VM running on a *nix host so I could just restore that VM to baseline as needed -- let them store whatever docs & such for school etc. on-line. To me it would be much easier keeping a copy of that VM current on my PC, then copying that single file over their existing copy as needed or warranted, rather than trying to figure out how or if they or some malware got around SD or whatever app to cause Windows to misbehave. Or I'd create a baseline disk/partition image backup once a month, then wipe the disk & restore that as necessary, e.g. on update Tuesday wipe the disk, restore the backup, update, then create a new backup image, restoring that image however many times till the next backup.

Hi, in my humble view (a regular Windows PC user) - Light Virtualization is a very useful technology if.. you fully understand how it works, what it does, what changes it will make to your "every day PC life" and decide for yourself which suits you better. The concept alone seems fantastic. Virtual (any way!:) PC contains "extra safe" virtual features (folders, programs, games, security Software) existing and leading their own life - within your PC, and yet "away" from it. The whole Structure of being relatively in "manual" control of your own Office - on your drives, in your folders and files is.. being partially (unless in full VB that is) - shipped to a different "keeper"? Like bank manager telling you your cash is much safer in his bank than in your home (and that's correct right?, lol)
Here - both your savings and cash in hand live under one roof, but you must understand that only cash in hand is something you have unhindered access to and control of.., the rest is a matter of trust and understanding.

[I used Sandboxie for a while (years back) being fascinated by it's concept, feeling smugly safe, happy, "with it", wow.. till it started crippling my movements, confusing me, getting in a way and I got rid of it. I'm not some "Luddite" smashing new technology and crawling back to my cave, I just didn't give it enough time and attention to fully understand how it serves me, simple. Earlier this year I installed on my lap Oricle VB in hope I can have XP on it (currently with Win7), but again leaving it unused and empty, asking the same old question - what exactly did I try to achieve there (in a meantime finding ways how "not to listen" to Win7 and making XP stuff workable within, and without VB, funny old world:), but enough rambling and confessions.]

In essence: Light Virtualization, or "Shadow Mode" (I did read Ashraf's "final verdict", as usual) - which Today's Giveaway of Shadow Defender 1.2 is based on - can only be of use to someone who fully understands how it works, on top of it(!) who can set it in a way so NOT to panic when Windows shuts itself down (without warning?, aaah:( and only if one's work (composing anything, game, post?) is perfectly saved on restart. Anyone having nervous disposition (or history of dealing with bsods..) might give it a miss. That is not to say this Software hasn't got it's useful merits and potentials. Is it beautify "too clever" and only for the brave and knowledgeable? Perhaps. Let's hope not major else is "wrong" with it.. I like to be protected, but for me personally - in more stable way. Sorry for banging on about virtualization "as such", but in today's Software I would have to take this aspect on board as well. Just my case.

Question to forum members who have already used/installed this GAOTD software. Does it offer an option that the software is started manually, rather than automatically with the system startup?

I hate the idea that I need to install any promising GAOTD or other software to see if I actually need it. So I think I would use it only to test new software in order to see if it suits my needs. Otherwise I would run my system in a normal mode.

Thanks in advance for your advice.

Awesome program! Way better than the similar Returnil (which I believe is no longer supported). If you have multiple hard drives you can choose which ones to protect. Great for testing new programs or something that might have a virus or cause a problem on your computer. I've been using it for over 6 months and have had NO problems with it. Uses a mere 4 Megabytes in memory when not in use.

#7: "Removes all changes to files, etc.? Maybe I don’t understand, but as someone who copy edits texts for a living, I make changes all the time in MS Word files that I want to keep. I turn my computer off every night, so does the morning bootup mean all yesterday’s work is lost? What happens to e-mails that get saved to my archives?
Am I missing something here or would I have to exclude any folder that changes during normal operations, e.g., Pictures, Documents, Pegasus mail folders, browser caches, Dropbox, etc.?"

You can exclude certain folders if you like -- I only protect the system partition [where Windows lives] & put anything I want to save on another partition that's unprotected. I currently use an old GOTD, Wondershare Time Freeze, when I'm afraid there might be compatibility problems with an app or driver, & that gives me the choice of discarding or transferring everything to the system partition -- I understand SD lets you commit those changes individually instead.

Of course *Any* unprotected folders, partitions etc. are all places malware could put stuff, so that's a potential weakness when it comes to security, if that's why you're running this sort of virtualization software. Most people have to pass at least some files in & out of Windows, or else you wouldn't need to worry about security in the 1st place, so you have to rely on AV software to make sure anything incoming is safe.

Do I understand it right that you can turn this on when you need it such as when trying out something etc, and at other times you can turn the protection off so you don't lose your work etc?

Just from what I found spending a few minutes using Google, the main Shadow Defender [SD] dev & owner was "away" for a while, but now he's back & allegedly everything's back on track with several recent improvements etc. Part of that comeback push is a spate of reviews [& perhaps SD's appearance on GOTD] -- here's 2:


Basically what these apps do is play man-in-the-middle, redirecting anything that would be written to your hard drive to a temporary file or files instead -- in order for that to work the app has to also monitor every Windows & software request to read from your hard drive(s) so it knows when to use the real files on your real hard drive(s), & when to point to the temporary storage instead. Obviously that has to add a bit of overhead, so like using a VM [Virtual Machine] stuff isn't going to work as fast -- most of the time that doesn't matter a whole lot, since we're only using some of the resources our PCs & laptops have available, but it can & does make a difference when you want to use everything your hardware can give you, e.g. hard core gaming, video rendering/encoding etc. Also, things do tend to slow down the longer you use one of these apps in a single session [before you reboot & clear the temporary storage] as the amount of temporary data that has to be managed keeps growing.

In order to work this sort of virtualization app normally uses a driver -- drivers can have or cause compatibility problems. It's not a bad idea to do a full disk/partition backup before installing most any driver. And in the case of an app like SD, Time Freeze etc., it's not a bad idea to just run with the app's protection active for a while to make sure there aren't any problems before you use them for something critical -- the way I look at it is you don't want to find out it's not doing it's job, not protecting your drive(s) because the driver's not working, when you Really need to count on that protection.

As far as the AV aspect of these sorts of apps, I think it's safer not to count on them to avoid or prevent malware, but rather to use them as an extra layer of protection *in addition to* the other security-related software you've installed & use... if nothing else, if they were 100% effective at blocking malware they'd be far more than the niche product they remain today.

Myself, & totally FWIW, I prefer to use VMs, using a virtualization app like SD only when a VM is impractical, e.g. monitoring/testing the install & operation of software &/or drivers for potential problems in my regular Windows install, but that's me & only one opinion. :)

@wt: no, by default the virtualisation is not enable, you can enable it for testing purposes and then disable it.

X64 version doesn't install. First time the 7zip extractor window came up but did nothing. Subsequent attempts do nothing at all except loading setup.exe into memory.

Windows 8 Pro
