Some types of computer malware are designed to capture your keystrokes and use the data to retrieve your usernames, passwords, email addresses, etc. These types of computer malware, also known as keyloggers, records everything you type so whoever planted the keylogger on your computer have access to your passwords no matter how secure the password might be. Keystroke Guard provides protection from keyloggers by encrypting everything you type, as you type and remains effective against these malicious programs even if your computer has become infected by a keylogger.
Since ransomware is designed to block access to your computer system until a ransom is paid, KG does not provide protection against ransomware and only claims to provide protection from programs that record keystrokes.
