Clover update r4318 being detected as Osx.Malware.Proton

ClamAV is finding Osx.Malware.Proton-6377366-1 in the file Clover_v2.4k_r4318.pkg/CloverPrefpane.pkg/Payload

The extracted content of the Payload file isn't detected as anything, though. Is this just a false-positive? I downloaded it directly from their SourceForge page via the update dialog.
