Based on some Googling I did on the two detections:
Avast-Mobile's Evo-gen detection is fairly likely to be a false flag, because it's a heuristic detection and seems to create false positives ALL the time, for all sorts of apps.
Symantec Mobile Insights' detection is a bit more.... uncertain. Can't make heads or tails of it, although I have seen one (yes, just one) post on github about a false positive with that identifier as well, so who knows.
