[clamav-users] Potentially False Positive, but I lost the file!

[Antonio Piccolomini d'Aragona]

Hi,
I'm writing for the following problem.

After sudo freshclam, I had a scan of my system (UBUNTU 12.04 LTS) by sudo
freshclam -r. ClamAv detected an infection relative to an ISO built from a
Windows 95 installation CD. The signaled virus was said to be a
Win.Trojan.Agent-18112140. Previous scans never reported infected files
(although the ISO has always been there). I submitted the file to the
VirusTotal online scan; there too, ClamAv reported the
Win.Trojan.Agent-18112140, being anyway the only in doing so (for all the
other checks the file was ok). Unfortunately, as I am moving and needed
have the computer with UBUNTU 12.04 turned into Windows, I formatted and
lost the incriminated file. So, I could not report the (potentially) false
positive to the ClamAv site. I just wanted to ask you whether I can be
sure, or should worry; I use computer for work, and handle important datas,
so I would like to be sure that that was actually a false positive (or in
which percentage it might be).

Thank you!

Antonio
