Since I need to limitate internet navigation to my workers I cancelled all DNS addres and I modified hosts files, writing in it all the sites permitted, but I am not able to update ClamWin Antivirus because I don't know exactly which sites I have to let permitted for to do this.
I wrote:
213.92.8.5 database.clamav.net
194.109.142.194 www.clamav.net

In which way can I modify the hosts file to reach the goal I want?
Thanks you very much in adavance
Best regards,
Amily
