You are probably compromized from the outside. There are jerks that love doing that so they can hide their identity. If it is coming from the inside, the culprit won't be able to get his job done -- too much goofing off. Their supervisor's will notice. This is what I would do: I presume you have a Linux computer at your disposal? I like this one: http://spins.fedoraproject.org/xfce/#downloads You can try it as a live CD first. (It really is a CD, not a DVD.) 1) make sure your Wireless access point (WAP) is using a good security protocol, such as WPA2. Note that WEP is virtuall no security at all. Change the logon password to the WAP, to keep other out and finding out the WPA2 passphrase. 2) change your WPA2 passphrase (password) to something 12 characters or longer. I find that phrases are easier for folks to remember. Love latin phrases. And don't tell anyone. Let them come to you. 3) See who is on your network with nmap. The "#" means root user: # nmap -sP your_network On mine network: # nmap -sP 192.168.1.0/24 Starting Nmap 6.25 ( http://nmap.org ) at 2013-10-10 19:11 PDT Nmap scan report for 192.168.1.1 Host is up (0.0022s latency).
