Once open, type netstat -n
It will display all activity. If you see anything out of place, dns the foreign hostname. If it doesn't resolve as anything familiar, then you are probably infected.
Go to task manager if this is the case. Find any unusual processes. If you're not sure, go to search on your pc and type the file name of the unfamiliar process. If its anything malicious you can then delete it. Make sure to wipe your registry, also.
Thank you very much for the response, currently I am disconnecting computers from my router, and watching the log. I'm pretty sure one of the computers has an infection since people don't take care of their shit..
