So far Mamutu has far outdone ThreatFire. I had them both running and did a few tests with downloaded keygens and cracks (using that idea from someone who recommended it in another thread ). I was really impressed that Mamutu was able to find and block the malware. Mamutu recognized it straight away and I was awestruck. Sadly however ThreatFire could not. Poor old TF, I loved you for a while, but you sadly could not outdo the competition. After not even giving me a warning about the executable (even with the extra rules), I have now decided to just keep Mamutu. Tell me your experiences with either TF or Mamutu. And please tell me in the poll whether you are impressed with Mamutu or not.
