I'm wondering, if already someone works on an adaption of the virus scanning add-on to Plone 5. There seemed to be two issues at the moment. The add-on in the collective github repository works only with the old AT content types. There is an old fork that solves this problem. I was able to merge this fork with the work in the collective repository. But the remaining issue seemed to be the controlpanel. The current add-on uses the import of form from from zope.formlib, which isn't available with default Plone 5 anymore.
