Is hacking into someones email illegal?

Did your hubby know your friend's ex. socially? It may be that the information comes from some casual chat rather than intercepting emails?

There a few keyloggers that can go un noticed by some of these spyware scanners.Thats why you should allways have at least 2 or 3 to use. If ex set up pc and he knows what he was doing, he may have very well placed a hardware keylogger instead of a software based one.

When you know a person, especially an ex partner, it is easy to guess there passwords, as most people tend to use memorable words. You could allways try an pick a pass for her.

You say he doesnt have access to house, but is your friend using a hard wired modem or a wireless router, if he is as strange as you say, he could be sitting near your friends house hooked into the wireless connection.

By contacting you with info he has gained from his ex then surely that is harrasement, and you could possibly gain a restraining order against him.

As this has been mentioned, the OP could also try a scan with Rootkit Revealer (http://www.microsoft.com/technet/sysinternals/Security/RootkitRevealer.mspx).

My own opinion however is that this is more likely to be a matter of tightening up home security of yours and your friends PC .
