It is never a good idea to spy on your spouse just because you can. If however you suspect infidelity you need to know the truth.
Not everyone has money for a private detective, but an easy and inexpensive way of finding out the truth is using spy software. These days most people who have extra marital affairs will at some point use a secret email account, facebook account or some way of communicating over the internet.
redpill offers a couple of spy software products including the popular and free redpill Spy.
Real spy software like the ones available from redpill will not let anyone else that is working on the computer know that it is installed. It is completely hidden and only you can open it and only you will know about it.
You will be able to see everything that was done. You will see screenshots of what your spouse was looking at and you will see everything that was typed. You will even be able to get the usernames and passwords of his/her secret email account or facebook account.
Even if the other person clears the history after working on the computer, you will still be able to see everything that was done.
To see how redpill Spy works, download the free edition. It is completely hidden and discreet.
