[Guest]

Hello everybody,
I'm using Endian Firewall Community 3.0.5beta1.
How can I upgrade the Clamav engine from 0.98.5 to the last 0.98.7?
In the Antivirus log I see:
freshclam (26857) Your ClamAV installation is OUTDATED!
freshclam (26857) Local version: 0.98.5 Recommended version: 0.98.7
Is there any way to update it?
Thank you.
Best regards.
Dario
