Hello,
To be sure the file is really a false positive pls upload it to https://www.virustotal.com/. If few (or no other) AV's find it infected it is likely to be a false positive.
Kindly notifify Clam team using the form @ https://cgi.clamav.net/sendvirus.cgi and tick the relevant field about false positive.
Usually issue is fixed shortly by the team and furthermore you will help to improve Clam/ClamWin detection ability.

Regards,

P.S.-In similar occurrances it could be useful to download and install the virustotal uploader (https://www.virustotal.com/it/metodos.html) which enables you to send the suspect file simply by right clicking on it and using the 'Send to' option (attention: max. file size acceptable is 20 MB).
PP.SS.-See you are still using 0.93.1 version. Suggest to upgrade it to 0.94 for better performance.

Antonio,

Thanks for your help. Followed your directions and will do so in future too.
