HTMLViewer Trojan or not?

Kaspersky and an another software say it is a Trojan.

Kaspersky:
Threat detected!
HEUR: Trojan.AndroidOS.Sivu.c
HTMLViewer
HTMLViewer.apk

Clean Master:
HTMLViewer [malware] Trojan

Is it a real threat or not? It cannot be stopped, removed, disabled etc.

I wouldn't rely on Clean Master if it told me that it's Saturday (it still is here). Kaspersky I'd believe. Disable it (using Link2SD if needed).
