New Security Look-up Service

Team Cymru has launched a Malware Hash Registry (MHR) service which allows you
to query its malware sample database for computed MD5 or SHA-1 hashes.

If your hash is on the list the query will return the last time Team Cymru saw your malware and give you an approximate anti-virus detection percentage.

Team Cymru says the Registry compliments an anti-virus (AV) strategy by helping to identify unknown or suspicious files that we have already identified as malicious. This enables you to take action earlier than you would otherwise be able to.

Queries, including reasonable bulk queries, can be made using the command line only. Best of all Team Cymru is making the service publicly available and FREE.
