Prevent unauthorized use of USB and other removable media with NetWrix’s USB Blocker

At times you want that no one else should be able to plug in a USB in your Windows PC. The reasons could be many. Maybe for security reasons or simply to stay safe from viruses that a USB may carry. This article would tell you about the USB blockers. We will talk of a good free USB Blocker: NetWrix’s USB-Blocker.

Rather than using hardware components, we can use this free software to block USB ports, so that if we want to unlock them immediately, you can do that. If you are cybercafé owner, a lab operator or your PC is connected to a public network you will definitely like this tool because sometimes nobody will be able to plug in a USB and put in the CD in the CD drive or send you files from network or share some files at network, which could result in some malware infection.

NetWrix’s USB Blocker

NetWrix’s USB Blocker not only offers to block USB’s on your PC’s, but also offers to block removable media in network. You can see who has plugged in any removable device in his computer from the network. Its installation process however may not be so easy for many.

USB Blocker doesn’t integrate as smoothly into Windows environment as other similar tools. It is a tool for geeks! There are some configuration changes which are detailed in the Administrator’s guide. You need compatibility of IIS, .NET, ASP on your machine – only then you can run the application.

Installing and configuring USB Blocker is best done by a Windows guru. However home users may need to take help of user guide but you can manage to get it installed. The freeware edition of this software supports 50 managed computers and provides full technical support in the network.

  1. NetWrix requires full contact information before it will allow one to download. Since that information has value, it’s not really, technically, freeware. Shame on NetWrix for both requiring it, and calling it freeware. It should be called “registrationware,” becausee that’s actually what it is.

    I agree with you Gregg!! it is registrationware but as it is free it is termed as freeware by company.

  3. Just because there’s no pound of silver involved doesn’t make it “freeware.” Again, one’s data has value; and the company is REQUIRING that data of value in exchange for access to the product. That’s a bona fide exchange of consideration in contract terms…

    …which means that it’s not, categorically, freeware; and so we shouldn’t call it that.

    I’m not trying to be a hair-splitting stickler, here. This is no small thing; and among those who actually think and write about freeware, open source software, donationware, registrationware, etc., there are not-insignificant differences between those things which should not just be shrugged-off…

    …especially when it can lead to a fundamental — even if inadvertent — misleading of the reader, and the direction of readers down a road which will, without warning, put them into the position of having to divulge their precious private information to feed some company’s marketing machine in order to avail themselves of what they thought was true freeware.

    Being REQUIRED to provide personal contact and other information (and, in the case of this company, more than just contact information is requested) about oneself or one’s company before one access what was purported and represented to be freeware — and I mean ACTUAL freeware; and which representation was the thing which induced the user to visit the company’s site to obtain the alleged “freeware” in the first place — is misleading and unethical.

    Conveying to the reader/visitor of/to this respected and normally trustworthy web site that the product is freeware, without any warning that personal information would be required (and so, therefore, it’s not really “freeware,” but, rather actually “registrationware”) facilitates the private company’s completely self-interested marketing goals at the potential peril of said reader/visitor. That, too, is unethical.

    Ethics is trickier than most people realize. That’s why there are entire masters degrees (in addition to entire undergrad courses) in the subject available from some of the finest institutions of higher education on the planet. What may seem a trivial thing and inconsequential thing (in the master scheme of things) to some — perhaps even to many… maybe even most — can, indeed, be QUITE non-trivial and QUITE consequential when examined more closely.

    We can quibble about it all day long but no amount of that will change the fundamental and incontrovertible fact that the company’s calling it freeware while requiring contact and other data of value for self-interested marketing purposes before one may actually obtain the software is disingenuous… maybe even technically illegal in “truth in advertising” terms; and this web site’s facilitating said company’s self-interested marketing goals, without so much as a warning to the reader/visitor that the actual cost of the so-called freeware is the giving-up of sensitive data of value (thereby actually making the product not freeware at all, but, rather, registrationware) plays straight into the hands of that bereft-of-ethics paradigm.

    Shame, then, on this web site for it. Don’t get me wrong, I’m not saying that it’s a HUGE thing, or the, as people say, “end of the world.” In the master scheme of things, this is small. And so all that I’ve written about it here may make it seem like I’m picking nits. But that’s the thing with ethical slippery slopes. They start small, and serve to habituate people to things which they should not so blindly and willingly accept. Lines not early drawn when it comes to things of that nature are lines easily and cavelierly crossed, until, finally, later, something REALLY unethical happens, and people are less able to recognize it.

    This line I draw here because it’s the right thing to do; to make a point worth making that personal contact and other data has value, even if no pound of silver is involved; and so when a company requires it in exchange for a product or service, said product or service is NOT free. People need to stop devaluing theiir information. Maybe information had little value in the industrial age, but this is the information age. Times change. We must all be aware of the salient things which such changes bring to our lives and ways of doing things.

    I humbly request that this web site add some kind of notation to the article-in-chief, beneath which this is a comment, which warns the reader that personal information will be required in order to obtain the software in question; and so, then, though nothing monetary need be paid to obtain it (and so, in that sense, some may think of it as “freeware”), it is, in fact, “registrationware,” and so if the reader does not want to provide his/her personal information, then s/he should just take a pass on the offer.

    Now, the interesting ethical paradox is that it turns out there’s an unethical way to get the software and STILL not provide personal information; and I could spell it all out here…

    …but, unlike the company which is actually offering “registrationware” under the guise of “freeware” (and possibly, also — though, admittedly, likely inadvertently — this web site which plays so willingly straight into its hands), I actually have ethics; and not descending slippery slopes matters to at least me. That said, I recognize that every human being has his/her own slippery slopes; and that ethics is not absolute across all humans (though there are certainly lines in the sand upon which most humans can easily agree). So I guess what I’m really saying, here, is that MY sense of ethics is guiding my behavior, here. Others’ ethics may allow them to behave differently, and in ways which may or may not be objectively unethical. Again, ethics can be a very complex subject…

    …complicated by the difference between knowing and acting. It is, for example, believed (and axiomatically said) by many that it is the ethical man who knows the thing is wrong, but it is the moral man who doesn’t do said thing because of it.

    But now I digress. Sorry.
