Could totally be a false positive, since 60 other vendors found nothing, virustotal is good and all, but you should really grow suspicious when it's 3+ (but depending on how many there are, and what specialities the vendors focus in)
I'd say just get Jiangmin (the vendor that flagged the file) and check the on-shelf version on what it scans, if it pops-out normal, then it's just virustotal being wacky--
virustotal also uses some out-dated scanners, and they could just being flagging codes that is per se, new to them, or they're reading code off of things and misconceiving it's purpose.
Any-who, it's best to do a re-scan with the real-deal, and maybe consult with Hachet is it persists- being, the vendor could totally be flagging some arbitrary code falsely.
