Antivirus is not updating (ReadyNAS OS 6.9.4)

Hi jereaa,

ClamAV has an automatic way to update, which is called FreshClam. One of our L3's ran it on debug mode. It can talk to the server but when it gets to 99%, it just stops receiving the data.

It was also found that we have an old version of ClamAV on the NAS. L3 tried updating it but seems like something is killing the connection at the very last second.

We would like to gather information about your network. I have listed below the information that we needed:

1. Name of ISP

2. Brand and model of the firewall router

3. What devices are connected in between the NAS and the firewall?

Regards,

Thanks for sharing this! Ran into something very similar on RN516 with 6.9.5 today. Only my 3 files were called *.cld instead of *.cvd.

Another issues seemed to be the outdated version of ClamAV: "WARNING: Your ClamAV installation is OUTDATED!"?

After running below procedure as you desribed with "freshclam -v", the antivirus was updated again. Not sure if "bytecode.cld" should also be replaced? This is the only file that doesn't have the date updated to March 23rd.
