Acespy Computer Monitoring Software is one of the best values for the money. This program is downloadable and extremely easy to use.
What I like the most is that it makes it easy to just sit back and wait as the activity logs are sent to you via email, and you choose where you want to receive these logs.
Hopefully it will bring back nothing but good news, but trust me, if there is something that your spouse or loved one is hiding it will be discovered.
