Malware in system apps

[insulindude]

Bluboo D1 - installed Comodo AV, initial scan showed Malware virus found in system app - com.android.snap. Can't uninstall, can only force stop! Have used Comodo all the time lately but thought I would try others to compare results, I tried Avast, AVG, Norton, McAfee and many others, all of which failed to find anything. Is Comodo just better or making something out of nothing and what's best to do?
