Comodo Internet Security 是一套非常知名的防毒軟體產品，包括防毒軟體以及防火牆，一般免費防毒軟體很少內建防火牆功能，但 Comodo 的免費版產品就是內建防火牆的網路安全套件。除了防毒、反間諜功能以外也兼顧到你上網安全。此產品提供了病毒防禦、網路防火牆與主動防禦（Defense+）三大功能，用來保護你重要的系統文件，完全不給病毒或惡意程式有任何機會侵入你的電腦。

        對於許多人，最熟悉的莫過於這個公司出品的免費防火牆，因為功能非常的強大。

        並且Comodo也是經常在各個病毒檢測實驗室接受嚴格的測試，從軟件No1寫的VB100的4月份測試結果這篇文章中，comodo也是有著不錯的成績，也是在大部隊中，非常的出色。

       這次的專業版，提供了非常全面的保護，它可以殺死木馬，病毒，蠕蟲，對於緩衝區溢出、0day攻擊、間諜軟件也不再話下。

       專業版中除了企業級的防火牆、殺毒軟件，最重要的還是那個defense+功能，有了這個先進的主機入侵防禦系統（Hips），可以大大降級對病毒庫和常規殺毒軟件的依賴程度，因為規則制定的好，可以防止大部分的病毒攻擊，甚至不用殺毒軟件都可以！

       這次的活動，可以讓你免費使365天，並且操作界面也是中文的。如果閒上面的功能還不夠多，還可以使用自帶的沙盤功能。
