Hi !Donovan,
Thank you for your analysis and report of this drive-by malware.
This is an interesting write up on loadus.exelator:

Summa summarum: There is no malware within the iframe itself, just a link to another
site that will attempt the exploit. And additionally know that NoScript extension in fx protects us against such drive-=by malware for Java malcode.
Creating errors from the Java Runtime Environment: as
#
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x7768de2d, pid=6960, tid=5736
#
So another reason to keep Java fully updated or run it on demand or de-activate it in the browser or even uninstall it (the last advice is not supported by avast officially, but some feel like this),
