Is there a remote monitoring software better than sniperspy than runs of XP,user friendly and clever? - email monitoring software

I did watch a couple of computers. I was told to use some attachments, Spy Sniper for download. I wonder if it discovers a smarter way to control without having to be. Spysniper is the best? Assuming that no information on the target computer. I know nothing about the purpose, perhaps only the e-mail. I want to know what is said in the queue, he, etc.
