Hey there!
Me and my brother are on a Lan here at home, and I think he is using one of those spying tools on me. MSN Sniffer or something. I was wondering if there was any way to avoid that, maybe by encrypting. Is there any tool that could avoid this?
try uninstalling any suspicious programs you think you have on your computer in control panel > add/remove programs. or you can get microsoft antispyware and with it remove the ghost keylogger that msn sniffer uses. then your brother won't be able to spy on you.
its not any kind of spyware. I have tried the MSN Sniffer program myself. There is no need to install anything on the other persons computer. It just seems that these conversations are unprotected and can thereby be seen through a lan network.
