[clamav-users] ClamAV not detecting viruses

[Andrew Wood]

Apologies if Im missing something obvious here but I have some 
attachments (.doc, .xls & .zip files) which came attached to spam emails 
which Im using to test out ClamAV on Debian Jessie (installed from the 
official Debian package).

Windows Defender says that they contain TrojanDownloader:JS/Swabfex.E & 
TrojanDownloader:o97M/Adnel but running clamscan on them says they are 
not infected.

The freshclam log shows that the definitions are being updated every 
hour, but Debian does not ship with a skeleton clamd.conf file and from 
Googling I cant work out if its required or not?

Is there any other reason why those infections would not be being detected?

Thanks
Andrew
