Nothing bad?
Get a clue.
Why would so many anti malware applications/vendors flagging it?
Antiy-AVL
Avast
CMC
DrWeb
Herdprotect
Kingsoft
MalwareBytes
Sophos
Tencent
TrendMicro
Zoner
and some others as well.

If they all are false positives, there very likely is something badly programed.
Yes, I know what zoek is and what it is ment for.
But be honest, it is not normal if it is flagged by so many.
