|So here is the truth, if it is truly your ip address that is being traced(Instead of your system having a rootkit). These are the steps I would take.|
1. Kill off your connection to the internet(unplug your computer/router)
2a. Ensure that there is no rootkit as suggested above. (rkill, tdsskiller,other back door software)
2b. Ensure that there are no other security issues.
3. Reset your router, and change the security to something different.
4. Have your IP address changed by your provider
5. Ensure that you don't accidentally give out security information that allows it to happen again.
