Tcpview is installed with the tutorial

anti-virus software, and the firewall is also available, but now the hacker's means are getting more and more sophisticated, and the way of stalling is unpredictable. Still ask a door god for your computer.

Tcpview is a free software developed by sysinternals.com. This software is not required to be installed in green software. It can be run by double-clicking after downloading. The main interface shows the port and thread opened by the current computer. The software directly displays the program icon corresponding to the port in the Windows 2000/XP/2003 operating system. It is very intuitive and can be seen at a glance what program is open on a port ( Figure 1). From here you can use the icons to separate which ports are open for normal applications. For those ports that the system itself opens, because the average user is not familiar with it, it can be judged by checking the attributes of the thread. The specific operation is to right click on these threads, select "process properties" in the pop-up menu (Figure 2), where the "path" item is the path of the corresponding program on the hard disk of this port. Usually the system files are in the C:\\WINDOWS\\system32 directory. If there is a similar name to the system program and the files are not in the system directory, then these programs may be fake system programs, most likely Trojans. //This article comes from the computer software and hardware application network www.45it.com

In addition, if you find some unfamiliar programs to open the port, you can also use google search to see the role of these programs If it is not found, it is very likely to be a Trojan. For these ports, we can close it directly by right-click menu!
