NetSpy - Version 3.0 With NetSpy you can see what web sites others are accessing from a PC. NetSpy runs invisibly so the user surfing the internet has no idea that big brother is watching them! Parents, use NetSpy to see what web sites your children are visiting and how much time they are spending on the internet. NetSpy will also record every key that a user types...even passwords! You can even read their private email messages after they've been deleted!
