Team Cymru has launched a look-up service that allows you to query their database of many millions of unique malware samples for a MD5 or SHA-1 hash of a file.
The service is free for non-commercial use.
The results of the query, will output the date the sample was first seen, and the detection rate of 30 AV engines.
Also you can cross check with the www.virustotal.com engine hash check option
