I put a keylogger on my home computer to record what my H was looking at. It's the best thing I have done, I have found out plenty since then.
the keylogger I have doesn't interfere with my spy ware, it's simple to use and it'sonly been installed for a week!.
My H is going through all MY files, none of his or mutual files, he's checking my documents, email, photos and such.
for me I put the keylooger on because of the situation we are in, there's a OW, H is lying, entering my bedroom while he doesn't live here anymore. I put a keylock on my door as well.
