Collaborative Filtering to Combat Viruses

Applying Collaborative AntiSpam Techniques to AntiVirus Problem

One of the most effective techniques available for combating spam is the widespread application of collaborative filtering, where members of a community identify and vote on spam messages.

However, it is not obvious that this also holds true for email-borne malware threats, whose sole indicator is often only a malicious attachment to an otherwise seemingly legitimate email.

We show that not only is a collaborative filter effective for filtering viruses, but also that the community begins filtering the virus within minutes of its initial detection—and with an extremely low false positive rate.
