In the backgroundjob rescan old files

The virus/malware definitions might have been updated. So it makes sense to just keep scanning the files.

I feel that this would create serious scalability issues, once enough files are stored that scanning them all takes >1d the scanner will just be running 100% non stop.

An alternative option might be to re-scan files on download if the last scan is old, it would add some latency to the download but doesn't cause a constant load

I mean we can also make it a week or a month. The time was just chosen randomly

@icewind1991 now it just keeps scanning every 28 days. Which it should I think so that if you have new virus definitions things still get rescanned etc.
