用于扫描你的电脑上所有的TCP端口的状态。利用这个功能，你可以轻松、快速的查出你的电脑上所使用的TCP端口，进而判断你的电脑是否中了木马。扫描出来的端口状态有两种：拒绝连接、接受连接。对于处于拒绝连接状态的端口，很可能是你的电脑为了与外部主机连接而使用的，通常情况下不会对你的网络安全构成威胁。而处于接受连接状态的端口，可能会对你的网络安全构成威胁，甚至很有可能是木马程序在运行!假若你想通过本端口扫描来判断你的电脑是否中了木马，在扫描时请不要运行其它网络程序，如果扫描结果还是有处于接受连接状态的端口，那请小心警惕!最好找个电脑高手来帮忙! 注意：对于137,138,139这三个TCP端口，即使这里的扫描没有给出扫描结果，也并不代表这三个端口不接受连接，通常情况下，Windows系统会开放这三个端口。你可以用“聊天客户”来测试这三个端口是否开放，具体用法如下：翻到“聊天客户”页，选择“主机列表”里的“本地主机”，将端口改为137(或138或139)，单击“连接”，若出现提示“建立连接”，则端口137(或138或139)是开放的。-used to scan your computer on all the TCP port state. Using this feature, you can easily and quickly identify your computer by the use of TCP port, then your judgment on whether a computer Trojan horse. Scanning the state has two ports : connecting refused to accept connections. For refused to connect at the state port, it is very likely your computer to connect with the mainframe and external use, under normal circumstances you will not pose a threat to network security.!accept the connection status of ports, care alert! finding the best computer experts to help! Note : This three TCP 137, 138 and 139 ports, even if the scanning here is not the results of the scan, it does not mean that this does not accept three port connectivity
