In Windows 7, reasonable use of some basic commands often plays a significant role in protecting network security. The following commands play a very prominent role, next we will teach you how to use the "netstat" command correctly to turn it into a Windows 7 security expert.
Detect Network Connections
If you suspect that someone else has installed a Trojan on your computer or is infected with a virus, but you do not have a complete tool in your hand
The netstat command can help us understand the overall usage of the network. Depending on the netstat parameters, it can display different network connection information. Netstat parameters, some of which are described below. How to detect whether there is a Trojan horse, the computer system backstage has been secretly manipulated, whether to be monitored. Today
