1. A computer-implemented method for controlling a computer device through a mobile terminal, comprising: storing, by a control center, terminal information that uniquely identifies a mobile terminal, and storing device information that uniquely identifies a computer device; storing, by the control center, a correspondence relationship between the terminal information and the device information to associate the mobile terminal with the computer device; receiving, by the control center, a first instruction sent from the mobile terminal; wherein the first instruction is to control the computer device; and, forwarding, by the control center according to the correspondence relationship, the first instruction to the computer device, wherein in response to receiving the first instruction, the computer device calls a first execution module to execute the first instruction, generates an execution result, and sends the execution result to the control center; wherein the control center is a cloud server, the terminal information is same as the device information; wherein the first instruction is an antivirus instruction; the control center receiving the first instruction sent from the mobile terminal, forwarding the first instruction to the computer device, wherein in response to receiving the first instruction, the computer device calls the first execution module to execute the first instruction, generates an execution result, and sends to the control center the execution result comprises: receiving, by the control center, the antivirus instruction sent from the mobile terminal, and forwarding the antivirus instruction to the computer device, wherein in response to receiving the antivirus instruction, the computer device calls an antivirus module configured on the computer device to execute the antivirus instruction, and when a virus is detected during a process of executing the antivirus instruction, the antivirus module sends virus information to the control center; the method further comprising: receiving, by the control center, the virus information sent from the computer device, and forwarding the virus information to the mobile terminal, wherein in response to receiving the virus information, the mobile terminal generates a second instruction based on the virus information received, and sends the second instruction to the control center; wherein the second instruction is to control the computer device; and, receiving, by the control center, the second instruction sent from the mobile terminal, and forwarding the second instruction to the computer device, wherein in response to receiving the second instruction, the computer device calls the antivirus module to execute the second instruction, and continues with an antivirus operation until the antivirus operation is completed.
