Trend Micro RUBotted is a small program that, while running in your PC, monitors any activity related to bots. RUBotted intelligently watches bot activity in your system to be able to detect anything that might be considered dangerous, either for your PC or for others.
Trend Micro RUBotted can monitor your system to see if any remote control or command sent by any bot is trying to take control of your system. The program looks at them to see if they are doing anything potentially dangerous to your PC (always related to bots), including en masse mail sendings - one of the tasks frequently run by PCs infected by bots.
RUBotted is an ideal tool to coexist with your normal antivirus, specifically watching activity related to bots. And don´t forget: RUBotted doesn´t need continuous updates to protect your PC.
