Mamutu

Mamutu monitors in realtime all active programs for dangerous behavior and blocks malicious activities. It recognizes new and unknown Trojans, Backdoors, Keyloggers, Worms, Viruses, Spyware, Adware and Rootkits (Zero-Day attacks), without the need of daily signature updates. Mamutu gives you full control over internal system activities. It's small but very powerful. Mamutu saves resources and does not slow down the PC.
