I am trying to learn so much I can about my total security 2011. I could find this setting called IDS. It was under antivirus/advanced settings. Intrusion Detection System is made for detecting "new zero day malware" and blocking it from infecting my system. Why is this off by default? Is it considered to be surplus to the requirements? If not, why is it not turned on as it would be extra good for the protection of my computer?
What is the better option for IDS when turning it on? Permissive og medium? I understand that if I turn it to aggressive then I could be some false positives and more alerts. But permissive and medium. What would be the best choice?
