Keylogger spyware records every keystroke on the infected system. Recorded keystrokes are then forwarded to hackers automatically through email. Generally, these programs are included inside of software which the user unknowingly downloads, thus totally bypassing the antivirus software and firewalls that are meant to keep them out . Be wary of software being offered for “free”. We recommend checking with reputable web sites like http://www.cnet.com to see if they have tested it first.
