Zemana AntiLogger is described as 'has a new, powerful way to protect your PC from malware attacks. We don't rely on virus signature updates and file scanning like the traditional anti-virus programs do'. There are six alternatives to Zemana AntiLogger for Windows. The best alternative is KeyScrambler, which is free. Other great apps like Zemana AntiLogger are SpyShelter (Freemium), Ghostpress (Free), Oxynger KeyShield (Free) and ScreenWings (Free).
KeyScrambler encrypts your keystrokes at the keyboard-driver level in the kernel as they enter the computer and decrypts the keystrokes at the destination application so that you see exactly the keys you've typed.
GuardedID takes a proactive approach to stopping malicious keylogging programs by encrypting every keystroke at the point of typing the keys, and rerouting those encrypted keystrokes directly to your Internet Explorer browser through its own unique path.
