SnoopFree Privacy Shield – Free Keylogger Protection

imageKeylogger malware, delivered by Trojans, and often incorporating rootkit technology, seems to be on the increase lately; much of it focusing on stealing victims’ banking credentials, including passwords. MMORPG (online multiplayer games), appear to be particular targets; especially WOW (World of Warcraft).

This type of malware is designed to remain undetected, and to be as stealthy as possible so that it can get on with its designated task, which most often results in identity theft and the compromising of the victim’s financial data.

Keyloggers are one of the most sinister types of malware; the type of malware that I pay particular attention to, and make a special effort to guard against.

A software keylogger, or system monitor, is a small program (not always malware, I should point out), that monitors every keystroke a user types on a computer’s keyboard.

This type of application does not necessarily require physical access to the user’s computer. It can be downloaded by someone who wants to monitor activity on a particular computer, or it can be downloaded unwittingly, as malware and executed as part of a rootkit, or a remote administration (RAT) Trojan horse.

Keyloggers are not restricted to software applications however, and are available as a connected hardware device designed for legitimate purposes.

From Wikipedia:

Hardware keyloggers are used for keystroke logging by means of a hardware circuit that is attached somewhere in between the computer keyboards and the computer, typically inline with the keyboard’s cable connector.

More stealthy implementations can be installed or built into standard keyboards, so that there’s no device visible on the external cable. Both types logs all keyboard activity to their internal memory, which can subsequently be accessed, for example, by typing in a secret key sequence.

A hardware keylogger has an advantage over a software solution; because it is not dependent on installation on the target computer’s operating system, it will not interfere with any program running on the target machine and also cannot be detected by any software. However its physical presence may be detected, for example if it’s installed outside the case as an inline device between the computer and the keyboard. Some of these implementations have the ability to be controlled and monitored remotely by means of a wireless communication standard.


A malware keylogger typically consists of two files: a dynamic link library (DLL) file (which does all the recording) and an executable file (.EXE) that installs the DLL file and triggers it to work. The keylogger program records each keystroke and uploads the information over the Internet.

Luckily, there are remedies for this type of malware threat.

SnoopFree Privacy Shield is a free powerful application that guards your keyboard, screen, and open windows from all such spy software. It makes it virtually impossible for any spy program to work on your computer since SnoopFree Privacy Shield’s protection works against spy software in real time.


I have been using this application for quite some time on my Windows XP machine, (unfortunately it only works on XP), and I have been amazed at the number of programs that have requested access to my keyboard and screen, particularly programs that I was in the process of installing.

Since I test a lot of applications on this particular machine, I see this type of program behavior frequently. Unless there are valid reasons for this type of access, I don’t allow it. Surprisingly, in most cases the application installs correctly. Curious!

If you’re serious about keylogger protection and maintaining your privacy, then you should consider adding this free application to your security toolbox. If you need more convincing, take a look at the “comments” page on CNET.

System Requirements: Unfortunately, this application works on Windows XP only.

If anyone knows of a similar free application that works on Vista and above, I would appreciate you letting me know

    “I have been amazed at the number of programs that have requested access to my keyboard and screen”… so have I.

    This is one of my must have programs, I’ve used it for a very long time and wouldn’t be without it. It’s really easy to use, if you’re not sure just click ‘deny access’. Great software.

    By the way, you’ll notice that my comments are like buses… there isn’t one for ages and then two come at once. But my dad used to tell me that if I had something constructive to say, then say it.. if not, keep your mouth shut, and so I always adhere to that golden rule 🙂

      Hey Proview,

      I’m only too happy to hear that you agree, so……………. I’m getting on your Bus.

    Hey Bill,

    I downloaded it and what do you know, Windows Live Mail was trying to access my screen (7 times too). Funnily enough, even after I denied it, WL still worked fine. Top program, this will be staying in the security toolkit.

    I always think I am covered and then something like this great program comes along and blows that out the window lol.

    I use Key Scrambler too, so with these two apps running, I feel very confident now.

    Cheers, and thanks for the good work.

    • Bill Mullins

      Hey Mal,

      I’m always amazed at the programs that want screen access. You just have act like a politician – deny, deny, deny. Glad you found it useful. Definitely wish the developer had kept going, and reworked it for Vista and Win 7. Oh, well.

      I’m with you, I wouldn’t launch Firefox without Key Scrambler.


  3. Liam O' Moulain

    Let me add my amazement to everybody else’s – amazing program! Thanks.

    Do wish it worked on Vista though.

  4. Leo

    Installed this.
    Rebooted and my XP machine went straight into a continuous reboot loop. Finally got it to re-start in Safe Mode and removed Snnop Shield – problem gone. Pity ’cause it would be good to have.

    • Bill Mullins

      Hey Leo,

      It sounds as if it’s conflicting with your anti-malware application/s. Are you running Comodo Internet Security Suite? I have heard that this may produce a conflict under some circumstances.


  5. Leo

    Hello Bill,
    Yes, I am running Comodo firewall and Nod32 so you’re probably right. I do like the sound of Snoop Shield but I had such a hard time sorting out a decent firewall that will co-habit alright with NOD32 that I would be very loathe to change that now. You do a great job there Bill. Keep up the good work and have a nice Christmas.

    Have you also heard of Zemana AntiLogger. This is a similar tool and supposedly has some good detection rate:

  7. Jeff C.

    Sorry forgot to mention in my previous comment that it also gets a very good Cnet rating and unlike the tool you mention it also protect against screenshot keyloggers.

    Without protection against screenshot keyloggers, this tool you suggested still leaves a gaping security hole for keyloggers to exploit.

    While not free, the price for Zemana is fairly reasonable and it only needs to be paid once.

      I hadn’t heard of this application until your email. Checked out Raymond’s review and a few others as well. Seems like this application stands up very well, and it has gotten some excellent reviews. I have added this app to my test projects list, and I look forward to testing it.

      Thank you for taking to time to let me know about Zemana AntiLogger – much appreciated.

      BTW, SnoopFree Privacy Shield does protect against screen keyloggers. The only major downside that I can see with this app is, it only works on XP. I combination with other suggested AV’s this app offers excellent protection.


  8. has the best WoW Fishing Bot available! It is the only WoW Fishing Bot updated for Patch 3.3 and Wrath of the Lich King. Existing at we also offer detailed instructions on how to apply this bot to make vast riches on World of Warcraft: Wrath of the Lich King by simply clicking a button!

  9. Jeff C.

    Bill, I did revisit the SnoopFree site and did see that it mentions protecting against screen loggers. Not sure how I missed that the first time but thanks for clarifying. It would be great if you could run the same Raymond cc tests on both these kind of a shoot out between the 2.

    Seems that SnoopFree has not been updated for some time now. I think the lastest version 1.07 was completed sometime in 2007. While Zemana is in beta with a soon to be 2.x version and seems to release several updates to the beta often.

    Nice thread going on about a recent great discount on Zemana over at Wilder’s forum.

    • Bill Mullins

      Hey Jeff,

      As I understand it, the developer has no plans to release an updated version of SnoopFree, and unfortunately the current application only works with Win XP.

      Thank you for the update on Zemana. I do need to take a closer look at this application and I have just downloaded the 15 day free trial version.

      Happy New Year.

    A bit late on this, but, as already said, just found out about you.
    SnoopFree sounds interesting and I’d like to give it a go. I have only one consideration: I’m using KeyScrambler Personal to browse the web and am really happy with it.
    Since SnoopFree isn’t updated, I fear of conflict between them.

    So, would you advice disabling KeyScrambler before testing SnoopFree?

    Thank you.

    • Bill Mullins

      Hey F.O.

      Do not disable KeyScrambler (a terrific application), since it performs a different function than SnoopFree.

      SnoopFree guards against the activation of a keylogger (malware), on your system, and will always appear live (active), in your system tray. It does a great job on XP systems, but Zemana is much more sophisticated.

      KeyScrambler, on the other hand, is designed to scramble any keystrokes you make in web site forms (web mail passwords and so on), only while you are connected to the net. Notice, it is only live while you are connected to the net – you’ll see the icon in your system tray. You’ll also notice that this icon turns green only when you are typing into a web form, otherwise the icon is amber.

    Hi Bill,

    Thanks for the reply & sorry for not replying sooner.
    Since I got a license for Zemana AntiLogger (thanks again!), I decided to pass on the try out of SnoopFree (it’s going to always be there, right?).

    I know how KeyScrambler works, my concern was about the combine a newer “technology” tool with an older one, if you get my point.

    Ok, have to do some reading now – absent for quite some time, must catch up.
