the crashes handled in bug 688895 have revealed some malicious addons, the codec addons are currently in the process of beeing blocklisted in bug 806451.
i'd suggest to also blocklist the bflix stuff on this occasion, which seems to be also quite crashy & have a look in which different variants it is occurring.

it seems to be from the same creators as the codec addons or at least follow the same patterns because the websites apparently used for the original distribution look quite similar: http://thebflix.com/ & http://allpremiumsoft.com/
Yes, according to this page: http://thebflix.com/index13.php, they are the same company.
