That would be between you, your management (if any), and your security
policy (should you have one).

What I would consider not safe at all is expecting us to know the local
factors that govern the trade offs between:

* The low probability, but potentially extremely expensive, scenario
where file turns out to have been capable of catching that brand new
nasty that just reduced your LAN to a smoldering ruin, and

* The much higher probability, but much lower cost, cases of false
positives.
