Its a tool that encrypts your keystrokes to prevent keyloggers from... logging your keystrokes
Keyscramblerie.dll installs with the QFX Software KeyScrambler Personal and KeyScrambler Professional. KeyScrambler was designed to defeat keyloggers by encrypting your keystrokes at the keyboard driver level. When the encrypted keystrokes reach your browser, KeyScrambler then decrypts them so you see exactly the keys you've typed. Keyloggers can only record the encrypted keys, which are completely indecipherable.

Best practices for resolving KeyScramblerIE issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active KeyScramblerIE process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the KeyScramblerIE.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
