My ISP sent me an email saying someone using my IP address has been involved in copyright infringing activity. I know who it is - I need to be able to monitor their Internet usage in order to lock down access to the sites they're getting to in these activities, and possibly even limiting the amount of bandwidth available to them or the PC they use. I've not seen a product that will allow for capturing and logging IP addresses access on individual PCs, an app that loads automatically and monitor/log in the background. The account in question is not an admin account. I don't have a gateway PC so this monitoring/logging app/software would have to reside on the PC.
