The method includes: intercepting a request packet sent by a user terminal to an Internet server and extracting Uniform Resources Locator (URL) information from the request packet; determining a security level corresponding to the URL information according to the URL information; and processing the request packet according to the security level. Therefore, the problem that the installation of antivirus softwares in the user terminal occupies memory space and CUP resources and the problem of the risk of being bypassed by malwares are solved, which effectively prevents malwares from spreading and attacking, reduces the threat to user terminals from malwares, and improves the network security and user experience. |
