Advanced Policy Firewall vs Dr.Web LiveDisk

Advanced Policy Firewall is a free GNU GPL firewall system for Internet-deployed Linux servers. It uses iptables/netfilter to combine static rules, stateful connection policies, and checks for attack patterns and forged source addresses. Administrators can configure granular inbound and outbound filtering, including rules based on users and applications. Additional controls include reactive address blocking, GeoIP country filtering, and Spamhaus and DShield lists. IPv6 dual-stack filtering can create ip6tables rules automatically. Documentation describes snapshots loading more than 1,000 rules in under one second, plus integrations with BFD, cron, systemd, Docker/Kubernetes, and logrotate. APF requires Linux, iptables/netfilter, and Bash, and supports legacy and nft backends. Listed systems include RHEL/Rocky/AlmaLinux 8 and 9, CentOS 6 and 7, Debian 12, and Ubuntu 12.04, 20.04, and 24.04. Development mode initially flushes the firewall every five minutes; only SSH port 22 is open by default.

Dr.Web LiveDisk is a free antivirus recovery tool for systems damaged by viruses or malware. It starts from a DVD or USB drive as emergency media, then launches the Dr.Web CureIt! scanner automatically. Users can choose a scan mode, run a quick scan or adjust scan settings. LiveDisk can remove viruses and suspicious files, restore infected items, and copy important data to external media or another computer. On startup it detects and mounts hard-drive partitions and establishes a network connection if possible. The included Midnight Commander file manager can search for and copy information, and the boot menu offers Memtest86+. Creating a USB drive requires at least 1 GB of free space; formatting is optional, and the creation application leaves existing files unchanged by default. USB booting requires BIOS support for a USB HDD device. Doctor Web advises checking that LiveDisk is current and updating its virus databases if needed, and lists 24/7 online technical support.
