clamav scan all raise exception

[akpotter]

modules/clamav.py , line 77 in ScanFile
if not os.path.exists(session_file.path):
ArrtributeError: 'Malware' object has no attribute 'path'

=====
I manually fixed clamav.py with "entry_path = get_sample_path(session_file.sha256)" in yarascan.py,
please check.
