[clamav-users] how to verify if a malware signature is in DB & adding hash

Need to clarify further based on the example in above link:
so if I have the MD5 hash but not the malicious file itself, I'd add the MD5
value into a line in  test.hdb & then run
  clamscan -d test.hdb  /    (ie scan for the MD5 in the entire server??)

But what I need is to find out if the MD5 hash is already incorporated
in our ClamDB (or is there a way for to trace back past virus-db releases)
assuming I have not subscribed to one??
