Mailing List Archive: ClamAV Queries on Maximum file size

I would like to get some details about the maximum file size clamAV can
support. As we got to know from the documentation that it supports upto 4GB
of maximum file size but would like any possibilities of extending the file
size and also let us know if there is any enterprise version of ClamAV
available.

Regards,
Deena

Can you tell us more about your requirements?

You should consider 2GBytes (not 4GBytes) to be the maximum file size:

To allow ClamAV to scan huge files is to risk crashing the scanner,
and there are other issues which may crop up too.

I don't know of anything which meets your description precisely. The
ClamAV maintainers are the folks at Cisco-Talos:

Cisco offers a range of product for protecting computer systems:

There are also numerous third-party tools etc. based on ClamAV:
