REC03 - Scan shared files for viruses

[Adrien Touzouli]

Find an open sourced antivirus

For unencrypted files, it would be possible to use a Synapse module base on check_media_file_for_spam hook

For encrypted ones, the files should be decrypted on the server side like Tchap does

Ask Matthieu and Yoan in Tchap team to see how they do the virus scan process

Can be avoided for the APE (cf. Laurent)
