It would seem that if files are being maintained in some sort of repository, then perhaps an antivirus filter should be applied to them at the point of entry. If a site allows anonymous users (or just not-too-bright ones) to upload files, then this could certainly become a problem. Check out ClamAV. It looks fairly easy to use, and has a MS counterpart. In fact, since it has a command-line interface, it might be a rather simple task to implement.

Yes this could be done, I will do this when I have time, and do it in filestore2.

All that really needs to be done is to add an extra field to the _settings() subroutine to tell filestre where the the clamav executable is, and then in the _validate() run clamav over newly uploaded files.

I know that Robert Douglas was working on an upload API (not filestore2, but drupal's built-in upload functionality). It has a validation hook that would allow such a feature to exist. The API docs are here: http://drupaldocs.org/api/head/function/upload_nodeapi

This still seems to be one of the most relevant threads about this subject, so just to say that this is the correct link for above:
http://api.drupal.org/api/function/upload_nodeapi/6

Looks like you'd need to add to the $validators array in the upload.module that passes values to includes/file.inc's file_save_upload() function and probably write a file_validate_virus_free() function to call clamav from the command line.

Anyways, there is a bit of interest in this idea (but it is also old now)
