Antivirus scanner definition file update failed

Thanks for that simple idea to try.  I tried it this morning, after getting another error messaging about being unable to update virus definitions.  Unfortunately, I got the same error message again after disabling antivirus, rebooting, waiting 20 minutes and enabling antivirus. 

Just to be sure, here's what I did:

I went to my Admin page and went to Settings

I clicked on Antivirus under Services and unchecked "Enable Real-Time Antivirus Scanning" then clicked Apply

I then hovered over the Power icon and pulled down to Restart and clicked that

After the NAS restarted, I waited 20 minutes, then went back to Antivirus and checked "Enable Real-Time Antivirus Scanning" and "Protect ReadyNAS OS" and clicked Apply

My logs show all of this activity, along with the "System: Antivirus scanner definition file update failed due to download failure.  Check your internet connection."  error message I received about 4 minutes after I went through that whole process and re-enabled the Antivirus.  But, I'm also seeing two other log entries about an hour after that error message that say "ReadyNASOS service or process (readynasd) was restarted." and "ReadyNASOS background service started."

So, I think I'll wait until tomorrow to see if I get another error message about antivirus updates.

OK.  I followed the instructions detailed by several people earlier in this thread (see the series of replies ending on 2020-12-17).

Here is what my last log entries say:

Dec 22, 2020 06:44:12 AM	System: Antivirus scanner definition file was updated to 59.26024.
Dec 21, 2020 06:43:13 AM	System: Antivirus scanner definition file was updated to 59.26023.
Dec 20, 2020 06:42:12 AM	System: Antivirus scanner definition file was updated to 59.26022.
Dec 19, 2020 06:41:31 AM	System: Antivirus scanner definition file was updated to 59.26021.
Dec 18, 2020 06:41:02 AM	System: Antivirus scanner definition file was updated to 59.26020.
Dec 17, 2020 03:33:07 PM	System: Antivirus scanner definition file update failed due to download failure. Check your Internet connection.

So I reckon that the best fix is the one suggested initially by NormanP and then clarified by StephenB.

Now all we need is for the next update from Netgear NOT to break this again.

And I just got the error message again saying the antivirus scanner definition file update failed to download.  So, unfortunately, that simple sounding fix didn't work for me.

A little disappointed, but my adjustments did not do the trick, so added 'capability chown' to file: usr.sbin.clamd (as stated in the same website) be continued....

Today the normal virus-update process was working; keep my fingers crossed the coming days.....

Being hopefull I solved my issue with the failed antivirus scanner definition file update :-)
my normal update-process is running fine now for several days.

so

1) stopping clamav: 'systemctl stop clamav-daemon'

2) stopping clamav freshclam: 'systemctl stop clamav-freshclam'

3) adjusting member 'usr.bin.freshclam' in dir: /etc/apparmor.d ; adding 'capability dac_override,' and 'capability chown,'

4) adjusting member 'usr.sbin.clamd' in dir: /etc/apparmor.d ; adding 'capability dac_override,' and 'capability chown,'

5) removing all file from dir: '/var/lib/clamav' (bytecode ; daily ; main ; mirrors ; antivir)

6) starting clamav freshclam: 'systemctl start clamav-freshclam'

7) reboot the NAS

did solve it for me (for now and starting from December 25th)

Please forgive my ignorance.  The code that you show looks somewhat like the old DOS code that I ran decades ago.  Where do you input this code?  Do you pull up a command line and put it in there?  I have been unable to find where these code lines are supposed to be typed in.  It would be a huge help if someone would start at the very beginning with how to get to where these lines of code are inputted.  I can't find where these filenames are located or where they're supposed to be downloaded to or changed.

Sorry, but it's been years since I was fluent in Assembler, COBOL, Basic, etc and everyone keeps putting solutions on here that are impossible for me to follow.  I'm about ready to just unplug the stupid NAS and plug it back in only whenever I need to access it.

These are Linux bash commands and they have to be typed into a bash shell.  To get there you need to log in to admin with your Web Browser, then enable SSH under 'Services' on the 'Settings' Page.  You will also need a way of issuing the ssh command on your PC.  If it is Linux, it's easy because you just open a Terminal.  On a Mac, it's probably much the same, but on Windows you will probably have to install an SSH client (I'm not a Windows user).

Make a note of your admin password and the IP Address of the ReadyNAS and then in a terminal type:

ssh root@<IP Address of the ReadyNAS>

and enter the admin password when prompted.

I can't vouch for the most recent fix, but I followed the instructions detailed by several people earlier in this thread (see the series of replies ending on 2020-12-17).  It has been working ever since.

I have enabled the SSH-service in my READYNAS and used WINSCP & PUTTY  to perform the several steps I did
(steps 1;2 & 6 in PUTTY and steps 3;4 & 5 via WNSCP (SCP-session))

AV updates have ran successfully for me since 13th December - hopefully ending 6 months of issues.

Very disappointing that Netgear have not contributed or commented on these issues or the fix proposed. It would be good to get their validation of the solution. I'm afraid this lack of Netgear input to what is a long standing issue with software and products they control and clearly should have the knowledge to fix only demonstrates their disregard, (even contempt), for their users and customers.

I agree.  This issue has gone on far too long.

I will certainly think twice before buying another Netgear product.

I have been a loyal customer for many years because of their support.  Netgear should realise that people don't judge a product on how many bells and whistles it has; they need it to continue working for a reasonable liketime too.  If Netgear becomes too much like some of their competitors and neglect support, they will soon find that these Forums will cease to be useful sources of information as people become disillusioned.

question/remarks from my site :smileyhappy:

Looking in the system logfile:
Jan 01 16:21:30 Geldrop clamd[13899]: clamd daemon 0.100.2 (OS: linux-gnueabi, ARCH: arm, CPU: arm)
Jan 01 18:55:01 Geldrop freshclam[17866]: Software version from DNS: 0.103.0

Is my NAS running with a mixed version of CLAMAV? the daemon with an older version (100.2) then the virus-file-updater (103.0)?
Should it not be the same , so all on version 103.0?
