I have a chatbot connected to IRC. It can do system calls, to access services running on my computer (winXP) and get back text information. I don't use that feature though. Now I added a capability to the bot, to learn new answers. The problem is that it can learn to start a system call simply by a user telling it so on IRC. :/ I can't prevent this atm, I could only turnoff the learning capability. But I'd rather not do that. So my question is: Can I safely prevent a program from doing any system calls? EDIT: I tried placing the bot in NOD32's or Avast's quarantine folder. That didn't work. I have a Sygate Firewall running, maybe that could be used to monitor the bot.
