Trust no one with your computer. Computer Security Consultant Darren Chaker notes that an adversary may install the Stealth iBot Deluxe which logs every keystroke typed from chats, Instant Messages, search engines, emails and control fields exchanged with your child, teen, spouse or employee. The software will also capture screenshots that you can set to meet your own monitoring preferences, like keyword/keyphrase triggers, which will send alerts to your email every time the keylogging software detects a word you've selected to monitor.
