Ransomware Files

We recently got hit with a SamSam attack and have a bunch of unwanted files on Box. How would I recursivly delete all files that have these two "Sorry-for-files.html" and "._weapologize" in there file name. Right now, I am actively scanning for "*Sorry*" files, but I believe scripting it would be better. Thank you for your assistance.

The easiest is to search for those files in GUI and delete the found files. Note the Delete button on Find dialog:
