How to scan bigger files?

Meghan,

256 MB is the maximum size (from online documentation) for HTTP/S and 204 for FTP.

Most of the time, malware are inside few KB/MB. Anyway vote the feature request:

256 was the limit in 16.0 I believe.  We upped it to 1536 (1.5 GB).

There is no real practical limit aside from harddrive size and how long you are willing to wait.

IIRC, very large files like that are typically either video - which cannot contain viruses, or they are things like DVD isos, which can contain thousands of files that need to be unpacked and individually scanned, which takes quite a lot of time.

I don't know the exact stats, but something like 90% of viruses are in files less than 10MB.

I'd be curious what the real world use case for unlimited file size scanning is.

Note: UTM limit seems to be 9999 MB.

Thanks Michael Dunn.

Make sure you update the Online Help and the Documentation too. My numbers come out from:

http://docs.sophos.com/nsg/sophos-firewall/v16055/Help/en-us/webhelp/onlinehelp/index.html#page/onlinehelp%2FWebSettingProtectionEdit.html%23

I always use 10 MB with some exception. Some organizations require that everything is scanned. Few times I configured even 100 MB.
