Full review

Launched in 2006 as one of the first keystroke encryption products, QFX KeyScrambler has continued to be popular with people wanting easy, effective protection from keylogger activity. The QFX KeyScrambler is available in a free (Personal) version, and in paid versions Professional and Premium. Premium is the highest priced business package and supports all kinds of apps, while Professional supports Windows apps and communications apps. Personal prevents keylogger attacks during browser activity.


QFX KeyScrambler is a comprehensive protective shield against all kinds of keyloggers – those we know, and those that could attack in the future. The system works by encrypting each character immediately as you enter it, and continuing to keep it encrypted thus making it incomprehensible for keyloggers to use. QFX uses standard symmetric-key encryption as well as asymmetric-key encryption. We like the live encryption action you can actually see working – as you type you can see how KeyScrambler is working by viewing the user interface – a green window – at the top of your screen. The standard free version only includes keylogger protection through the browser. The premium version covers more apps, but webcam protection is not included, nor screen capture, clipboard capture, microphone capture, computer registry or RAM. QFX KeyScrambler has fewer features than other anti-keylogging software, and doesn’t have password-protect features, or anything to protect the entire system from hackers.

Ease of use

QFX KeyScrambler is quick and easy to install and afterwards is very easy to run. You almost don’t need to do anything. This cuts down on the personalization options, but it is really one of the simplest solutions if you don’t want to have to deal with configuration or more advanced settings. The file size is small and it is generally unobtrusive. If you like to see exactly how a program is protecting your computer you can with QFX and its real-time encryption taking place on screen.

Help & support

The online support section on the KeyScrambler website is one of the most comprehensive we've seen, but it is not particularly user friendly. You have to look through a lot of different sections to find answers to FAQs. No phone support is available - email the company directly if you need help (they say they will reply promptly.)


The standard versions of QFX KeyScrambler work fine for protecting you against keylogger activity while browsing the internet, but if you are looking for extra features and an extra layer of protection this is not a particularly comprehensive package. Depending on what you are looking for there are more complete packages available.
