It would probably be a good idea to implement ulimit
restrictions on the user that the software runs as.

Mostly "root"...and this will cause sure other fun, looks 
like some software didn't expect that file system runs out-of-space
and still 
hang and have no fail-safe mechanism here... 

If your antivirus software (which, by definition, is routinely exposed
to 'malware') runs as root, then you have worse potential issues than
just a bzip bomb consuming resources.
