Zemana AntiLogger Free is a program that protects your computer from keyloggers by encrypting your keystrokes. When a computer is infected with a keylogger it can see and record all keystrokes that you type on your computer. It can then log this information and send it to a remote location so that the user can steal your passwords, account credentials, and personal information. By using a program like Zemana AntiLogger Free, your keystrokes are protected from unauthorized access by encrypting what you type so its only accessible to the program you are using.
