can you try this?
open command prompt
the call nslookup
at the prompt enter
set querytype=txt
then
current.cvd.clamav.net
the output should be like
Non-authoritative answer:
current.cvd.clamav.net text =
"0.91.2:44:4376:1190615341:1"
cvd.clamav.net nameserver = ns7.clamav.net
cvd.clamav.net nameserver = ns1.clamav.net
cvd.clamav.net nameserver = ns2.clamav.net
cvd.clamav.net nameserver = ns3.clamav.net
cvd.clamav.net nameserver = ns4.clamav.net
cvd.clamav.net nameserver = ns5.clamav.net
cvd.clamav.net nameserver = ns6.clamav.net
ns7.clamav.net internet address = 209.204.159.15
ns1.clamav.net internet address = 216.15.159.94
ns2.clamav.net internet address = 63.166.28.2
ns3.clamav.net internet address = 195.70.36.141
ns4.clamav.net internet address = 209.9.232.3
ns5.clamav.net internet address = 213.92.8.2
ns6.clamav.net internet address = 208.201.249.238
ns5.clamav.net AAAA IPv6 address = 2001:1418:13:1::1

where "0.91.2:44:4376:1190615341:1" is the data freshclam needs
can you also try nslookup, then:
database.clamav.net
you should have something like:
Non-authoritative answer:
database.clamav.net canonical name = db.local.clamav.net
db.local.clamav.net canonical name = db.it.clamav.net
clamav.net
primary name server = ns1.clamav.net
responsible mail addr = hostmaster.clamav.net
serial = 2007091501
refresh = 3600 (1 hour)
retry = 900 (15 mins)
expire = 604800 (7 days)
default TTL = 7200 (2 hours)

where the alias is geolocalized db.it.clamav.net -> Italy
additional info in the freshclam code,
they added a workaround disabled by default, for an alcatel modem
The DNS server in the SpeedTouch Alcatel 510 modem can't
handle a TXT-query, but it can resolve an ANY-query to a
TXT-record, so we try an ANY-query now. The thing we try
to resolve normally only has a TXT-record anyway.

or more simple when freshclam starts your network is not yet initialized, so you can update manually or don't use update at logon,
currently freshclam doesn't wait for the connection to came up and anyway an update at logon would never work
if the network is not ready
