1. A method of generating a reference file set having high-confidence malware severity classification, comprising:
selecting a subset of files from a group of files first observed during a recent observation period;
polling a plurality of other antivirus providers for their third-party classification of the files in the subset of files and for their third-party classification of a plurality of files from the group of files not in the subset;
determining a malware severity classification for the files in the subset by aggregating the polled classifications from the other antivirus providers for the files in the subset after a stabilization period of time; and
adding one or more files having a third-party classification from at least one of the polled other antivirus providers that changed during the stabilization period to the subset.
