IDP.Generic found in updater for a trusted program. FP or infected update?

Freemake Video Converter’s latest updater was quarantined, after downloading and launching, for IDP.Generic.3681c591d46a.3.2. When Freemake (pre-update) launches, it checks for & d/l’s updates & offers to install. If I run the pre-update Freemake in the sandbox, it stops execution before offering to install update.

Does this indicate that the update is truly infected, or might this still be a false positive?
