[K12OSN] Virus in one of the packages in 4.2?

[AIMSSDA]

I was scanning my samba file server when bitdefender came up with this 
report.

Z:\ISO\K12LTSP-4.2.0-disc2.iso=>Fedora/RPMS/rpm-devel-4.3.2-21.i386.rpm=>rpm-devel-4.3.2-21.gz=>K12LTSP-4.2.0-disc2.iso=>Fedora/RPMS/rpm-devel-4.3.2-21.i386.rpm=>rpm-devel-4.3.2-21=>usr/share/doc/rpm-devel-4.3.2/apidocs/html/header_8h.html

is infected with this:

Trojan.Clicker.Qhost.A


Is this a false positive or really a virus.

Thanks

Edward
