This alert means that the JPEG is slightly malformed.  Many applications will probably be fine with it.  ClamAV thinks it is a little odd.  The risk is probably pretty low, but perhaps looking at a little to see if any other antivirus products think it is suspicious.

for me look it like that the jpeg files cannot be read from heuristics scan as reason that something is wrong with it
i would not think frist, that is be an exploit

> A clamdscan flagged quite a few files on my system as Heueristics.Broken.Media.JPEG.JFIFmarkerBadPosition. What kind of exploit is that? And what kind of danger does it pose? (What does it do?) Is it for all systems? Or just for Windows?
