Looks like we have several files with trojans etc. being uploaded. I don't know if this is expected or not. See some examples here: http://lists.wikimedia.org/pipermail/xmldatadumps-l/2012-July/000567.html (currently being deleted, see some dates on https://fj.wiktionary.org/wiki/Special:Log/Erafosu ).
Nemo, thanks for opening this. We currently are not scanning pdfs. We may start doing that, or may implement this as a bot to scan and flag suspicious pdfs after they have been uploaded.
