# Author: Jesse Lang | http://jesselang.com/

# Use it with "find" like this:
# $ for FILE in $(find -iname *.php); do python malware_cleanup.py $FILE; done
# This script takes one argument, a file path.
# The file is opened and scanned for a match.
# The user is given the option of cleaning or deleting the file, or doing nothing.
# If repairing the file would result in an empty file, the file is deleted instead.
