Squid3 Proxy Configuration for Network Malware Protection

Step-by-step configuration instructions for Squid3 to use Malware Patrol blocklists: create a malware_patrol_update.sh script to download the blocklist via wget, set execute permissions, add ACL lines to /etc/squid3/squid.conf to deny matched URLs and provide a deny_info page, run the update script to reload Squid, and schedule an hourly cron job to refresh the list. The guide includes example commands, formatting notes for the download URL, and a support contact.
