Keylogger access is often downloaded inadvertently by users clicking on links in fraudulent e-mails and poses a dangerous threat to user privacy. A keylogger is a computer program that logs each keystroke a user types on a keyboard and saves this data into a file or transfers it via the Internet to a pre-determined remote location. It also can capture screenshots of the user activity, log-in passwords, record online chat conversations or take different actions in order to find out what a user is doing. Trojan horse programs (including Remote Access Trojans or RATS) can be hidden in games, videos, music files or programs downloaded from the Internet or e-mail. The download installs a malicious program on the target’s computer. Many anti-virus programs will detect and remove Trojan horse programs, but must be regularly updated to be effective.
