It is important to check all files uploaded onto a file server or in the cloud e.g. through AWS S3 for virus, trojans and malware for security reasons. Without such support the file servers may get infected and also the community users can get their mobiles/tablets/PCs infected.

I hope you will consider support for e.g. ClamAV on the file server for those that have installed it. ClamAV works fine on Linux and when running in memory it is really fast.
