This is a Bug in HAVP service on Endian 2.2 Final, to solve this problem you need fix two broken symbolic links: /etc/havp/whitelist and /etc/havp/blacklist
# touch /var/efw/havp/whitelist
# touch /var/efw/havp/blacklist
# chown nobody.nobody /var/efw/havp/whitelist
# chown nobody.nobody /var/efw/havp/blacklist
# reboot
After restart you can use Antivirus module, hi is working again
ps: i'm not speak english...sorry my bad english
