On a test server after a very long period of not detecting anything CLAM 
AV started reporting that it was seeing:

/clamscan/servers/mudlake/opt/Dave/nmap-4.03.tgz: Trojan.Spy-27244 FOUND
/clamscan/servers/mudlake/opt/Dave/nmap-4.03/mswin32/winpcap/Packet.dll: 
Trojan.Spy-27244 FOUND
/clamscan/servers/mudlake/opt/Dave/nmap-4.03/mswin32/winpcap/WanPacket.dll: 
Trojan.Spy-27239 FOUND

and:

/clamscan/servers/mudlake/rootdir/usr/src/packages/BUILD/nmap-4.03/mswin32/winpcap/Packet.dll:
 
Trojan.Spy-27244 FOUND
/clamscan/servers/mudlake/rootdir/usr/src/packages/BUILD/nmap-4.03/mswin32/winpcap/WanPacket.dll:
 
Trojan.Spy-27239 FOUND
/clamscan/servers/mudlake/rootdir/usr/src/packages/SOURCES/nmap-4.03.tgz: 
Trojan.Spy-27244 FOUND

The files in these directories are unchanged since 2006 so I'm curious if 
this might be a false positive.  I ran freshclam and re-scanned these the 
directories /opt/Dave and /usr/src and that didn't weed out a possible bad 
signature.

While the person who owns /opt/Dave is currently not awake, this appears 
to be a 'roll your own' installation of nmap-4.03 and finding that on this 
system is not surprising.  What worries me is that it seems to have found 
a match in the mswin32 directory and that this might be valid.

How do I check on signature entries Trojan.Spy-27244 and Trojan,Spy-27239 
for how recent they are, and is there another means to reality check this 
result. I am not above wiping these directories from the server, but I 
want to understand whether or not this is a real detection.

Thanks!
