Pfsense as UTM

[Glacier]

Hello

Im building a pfsense box which is supposed to function as an UTM firewall.
Im running Snort for Intrusion prevention and SquidGuard for content filtering.
However im a little lost on what AV to use. I know squid has ClamAV buildin, but i have absolutly no idea on how good ClamAV is.

How does it fair against the commecial products ala ESET, Kaspersky, Sophos etc?

Are there any other solution worth mentioning?

Considering the amount of HTTPS traffic, virus scanning on the firewall is pretty much a fool's errand.

So rather only do the AV check client side?
