[Solved] How to update ClamAVNet anti-virus code manually? (Suitable for Synology/QNAP NAS)

Synology kb shows, that the "Antivirus Essential" can update the antivirus code automatically, but if the external network is inaccessible for your device.

You can try to download those files via the ClamAVNet database website.

• daily.cvd
• main.cvd
• bytecode.cvd

BUT

    https://www.clamav.net/downloads

No download link after visiting the ClamAVNet database instead a document to teach you how to set up a private local mirror.

Please download each file manually from different region websites [List.1] and then deploy it to NAS.

P.s:
The IP will be blocked by ClamAVNet download station if accessed multiple times in a minute, this way can prevent high internet traffic of ClamAVNet.
