Also, are you using WIFI? There are new HACK tools out there. Read about my encounter with them and how we fixed it at http://forums.cnet.com/5208-6132_102-0.html?forumID=32&threadID=242736&messageID=2457489
Finally, don't allow ANY spyware or malware on the machine as they can install emailers, P2P softwares and more. Read http://forums.cnet.com/5208-6132_102-0.html?forumID=32&threadID=238606&messageID=2432058 about free tools to detect such.
In closing, if they limit your GB most ISPs offer an "shut off" or "limiter" to such accounts. Be sure to research what you can do to limit the bytes.

Hello,
I have max 3 or 5 gb megabytes of download in a month on my adsl connection. I recently discovered that somebody surfed with my account data and wasted a lot of megabytes so my bills will be high this month. Is there anything that I can do to protect my self against it except changing my account password?
Regards,
Mirza
