Oh. :( I wondered why that was happening. Is there nobody here that can
offer any "DoS proof" hosting for him?

Hmm. If that caused clam to break, then the script you're using is not
very well written. I wrote the below script to download clam sigs and
have been using it on several systems for over a year now. It uses
clamscan to verify that the signature file is valid before passing it to
clamav. Also, it does a HEAD before the GET, and doesn't GET the
signature if it's last modified time hasn't updated since the last download:
