That's fine.  All of those functions get called one after the other in
the same process.

So initialize your variables in filter_begin.  You can define them
in filter/filter_multipart and they'll be available in filter_end.

sub filter_begin
{
	@extensions = qw();
	@filenames = qw();
	@viruses = qw();
}

sub filter
{
	# ...
	push(@extensions, $some_extension);
	push(@filenames, $some_filename);
	if (virus_found()) {
	        push(@viruses, $some_virusname);
	}
}

sub filter_end
{
	# You can use @extensions, @filenames and @viruses here
}
