• and
• one or more programs stored in the memories and to be executed by the processors, the programs further including instructions for:
• a website address acquiring module, configured to acquire a target website address in a network access request from a user terminal;
• a processing module, configured to determine whether the target website address is a malicious website address based on a domain name in the target website address and/or an extension of a file name comprised in the target website address;

• a sending module, configured to send prompt information of intercepting the target website address to the user terminal if the processing module determines that the target website address is a malicious website address,
• wherein the processing module comprises:
• a pre-processing submodule, configured to determine whether the target website address is a potential malicious website address based on a domain name and/or an extension of a file name in the target website address,
• a website address cloud query submodule, configured to match the target website address against a reference website address in a preset malicious website address database, if the pre-processing submodule determines that the target website address is a potential malicious website address, wherein the reference website address is a malicious website address;
• and determine that the target website address is a malicious website address if the malicious website address database has a reference website address that matches the target website address;
• wherein the processing module further comprises:
• an acquiring submodule, configured to acquire first page content of the target website address if the malicious website address database does not have a reference website address that matches the target website address;
• a page resolving submodule, configured to resolve the first page content;
• a page screenshot submodule, configured to, if the first page content is less than a preset value, acquire second page content corresponding to the target website address, and generate a target page picture corresponding to the second page content;
• and
• a determining submodule, configured to determine whether the target website address is a malicious website address according to the target page picture.
