I'm new to VirusTotal but playing the devil's advocate... if I was developing a virus, knowing file size limitations of a front-end virus uploader/feeder (like VirusTotal) to other virus scanners, I would make sure my infected file exceeds these limitations making it more difficult to detect simply because end users are hindered from uploading it.
While I understand why there are limitations the question is what is the criterion for selecting a maximum file size in the first place? Why 128MB? Why not 130? 125? Are uploaded files kept indefinitely? Do they need to be kept at all?
Thx,
