Different software titles allow the recording and logging of different applications. They may monitor keystrokes typed, chat conversations, emails, web sites visited, software opened, documents opened, or all of the aforementioned. Some also provide blocking of certain applications such as chat, and others the provision to be discrete or not.

Spy Software requires the user to physically install the software on the computer or network to be monitored. This is in vast contrast to 'spyware' which attempts to load itself onto other peoples computers through deceitful means - such as installing itself by being bundled with a screensaver download.

There are many reasons for employing computer monitoring software, and it is commonly used throughout the world by concerned parents, spouses and partners, government departments, educational institutions, and employers. Whilst spy software can be an excellent tool, laws in your area may prohibit its use in full or part, depending on your intended application. If you are in any doubt as to its legality for your specific use, be sure to seek legal advice.
