[Antivirus] Failed to update virus definitions

Post by davidc1023 » Tue Jan 14, 2020 6:51 pm

Hi All,

I've been getting the error below since early December 2019.

"[Antivirus] Failed to update virus definitions. No storage volume detected. Create a new volume"

I've done some research and come across a few articles saying creating a new storage volume will fix the issue (doesn't fix it for all users apparently). We're not able to do this as our current storage pool takes up the entire drive(s) capacity. I've also pulled the latest definitions of the ClaimAV Virus Database and tried to putting the .cvd file in to manually update however I'm getting an incorrect format error.

I'm not sure what else to do other than trying to find another third-party AV from the app store.

Any input is greatly appreciated.

hope its not this..


if it is your NAS maybe infected.

do you have upto date firmware installed on your unkown nas?

do you have the latest Malware Remover installed and have scanned your system?

also add Security Counsellor app to harden your NAS.

also use the search feature and search for the phrase.


failing this raise a ticket with QNAP. let them fix it.
