Proxy server-based malware detection

A method, comprising:

• receiving, via at least one of one or more computing devices, a proxied request from a client device for a network resource from a network site;
• determining, via at least one of the one or more computing devices, whether the network resource is correlated with malware based at least in part on a browsing history associated with at least one other client device;
• executing, within an execution environment of the one or more computing devices, the network resource in response to determining that the network resource is correlated with malware;
• and
• determining, via at least one of the one or more computing devices, whether the network resource comprises malware based at least in part on the execution of the network resource.

A non-transitory computer-readable medium embodying a program executable in at least one computing device, wherein when executed the program causes the at least one computing device to at least:

• receive a proxied request from a client device for a network resource from a network site;
• analyze the proxied request to determine whether the proxied request includes protected information transmitted in an unsecured manner;
• determine whether the network resource comprises malware based at least in part on an execution of the network resource or whether the proxied request includes the protected information transmitted in the unsecured manner;
• and
• send data generated by the network resource to the client device in response to the proxied request when the network resource is determined not to comprise the malware.
