[clamav-users] Signature not detected

[Alex]

Hi, we've received a word virus that isn't currently being detected by
any scanners. I've submitted the FN, but would like to see if we can
get that pushed out as soon as possible.

It's not currently being found by any scanners:

Also, there's some notes in the "comments" section of this post. What
does it mean? How can I use that to my benefit in the future?

Is there any way a postfix/amavisd/spamassassin/clamav user can
benefit from this information by blocking based on that signature
provided?
