If you would like to know more about the behavior of a particular malware, but you do not want to build your own sandbox or you just have not the resources to build it then may be you can find Anubis service suitable for your needs and pretty convenient.

Anubis had been developed by IsecLab.
As an input the system expect either URL or binary, so you could feed both – suspicious URLs and files.
The analysis took some time so you have basically spare half an hour or more for something else.
The result of the Anubis is a full report containing details for the malware behavior:
– registry activity – keys accessed and modified together with the key values
– file system activity
– network activity – in the form of .pcap file
The report is downloadable as XML, PDF, TXT or HTML file.

In other words this is fully accomplished product you can benefit.
