A specific command format is: netstat-an command to see all and the local computer to connect IP, which contains four sections - proto (connection), local address (local link address), foreign address (and the local establishment connection's address), state (the current port state). For more information through this command, we can fully monitor the connection on the computer, so as to achieve the purpose of controlling the computer. All the best.

A long period of time, a malicious attacker who love to use cloning methods to control the account on your computer. They used way is to activate a system, the default account, but this account is not frequently used, and then use the tool to upgrade this account to the administrator privileges, from the surface, it seems this account is the same as the original, but the cloned account is the system's biggest security risk. A malicious attacker can arbitrarily control through this account on your computer. Method is direct input "net start" to see the service, and then "net stop server" to prohibit service. Check and reply.

In order to avoid your situation, you can use very simple method accounts for testing. First, the command line, enter net user, see what the computer user, then use "net user + user name" see what permissions the user belongs to, usually apart from Administrator is the administrators group, others are not! If you find a system, built-in user belongs to administrators group, then almost certainly you have been invaded, and someone else on your computer cloned accounts. Quick to use "net user username / del" to delete the user bar. All the best.
