Abstract: A method and system for detecting network link are disclosed. The method includes: receiving copy content by capturing a copy behavior; performing malware detection on network link in the copy content to obtain a detection result; generating a risk warning message according to the detection result. The system includes: a receiving module, configured to receive copy content by capturing a copy behavior; a detecting module, configured to perform malware detection on network link in the copy content to obtain a detection result; a message generating module, configured to generate a risk warning message according to the detection result. The method and system can reduce the attack risk of malicious network link.

Abstract: A method for controlling a page jump includes transferring a jump parameter value for the URL that indicates one or more domain names. The one or more domain names identify domain names a terminal is permitted to navigate to, from the URL. The method also includes receiving a request to navigate from the URL to a second URL; determining whether a domain name of the second URL is included in the one or more domain names indicated by the jump parameter value for the URL; and, in accordance with a determination that the domain name of the second URL is included in the one or more domain names indicated by the jump parameter value, permitting navigation to the second URL.

Abstract: Embodiments of the present invention disclose a system and a method for processing similar emails, and relate to the field of web technologies. The system includes: a control node, configured to receive a sample of a preset format, and determine whether the sample of preset format is a final result of similarity computing; if not, combine or split the sample of preset format according to a preset criterion to obtain multiple subtask packets, and allocate the multiple subtask packets to multiple similarity computing nodes; and multiple similarity computing nodes, configured to: compute similarity relationships for the samples in received subtask packets to obtain an intermediate similarity computing result that is a sample in the preset format, and feed back the sample in the preset format to the control node, where the intermediate similarity computing result includes a unique similar sample, a similarity relationship, and similarity count of unique similar sample.
