After testing several free keyloggers, we’ve picked what we thought were the best and sorted them into a top 10. Free keyloggers are often more limited in functionality and stealthiness. There are many software keyloggers around, some are freeware while others require a paid license to use. However, it can also be used for illegal or unethical purposes such as stealing passwords, reading private data and etc. Or maybe even monitoring an employee making sure that they do not copy or leak out any confidential files. There are many legitimate uses for a keylogger such as monitoring your children, making sure that they stay safe on the Internet especially when chatting and making friends with strangers. They’ll have to depend on security software like anti-keyloggers or antivirus packages to tell them that a keylogger is present on the system, or else they will have no idea that things they do on the computer are being monitored.
A software keylogger can be run in the background and not get noticed by average users. A keylogger can be either a piece of software or a hardware device that can capture the keystrokes typed on the computer’s keyboard.
