Working alternative antivirus solution for NAS models with less than 1.5 GB of RAM?

[bseesing]

My backup machine is an 8 year old TS-221 in perfect working condition, running firmware 4.3.3.1432 Build 20201006. Since about two weeks the built-in Antivirus refuses to automatically download the daily virus definitions. Doing some research, I found out that the built-in CLAM AV antivirus engine is end-of-life and thus actively blocked from downloading updates.

Following the information on this forum (viewtopic.php?f=345&t=159990) I found out that I have a problem, since my TS-221 only has 1 GB of RAM. Clam AV nowadays requires at least 1.5 GB of RAM to run, and so does the Sherpa / Clam AV solution mentioned in the other topic.

Manual updates do work (I download the definition files here http://www.clamwin.com/content/view/58/27/), but are not a viable option for my remote machines. And there is no alternative virus scanner available in the App Center for the TS-221. Thus I opened a support ticket to request an updated firmware with an updated virus engine.

QNAP confirmed that they will not release an updated firmware for my TS-221 given the system requirements of Clam AV and the EOL status of the TS-221. They recommend to use alternative antivirus apps such as McAfee if available on my NAS model. My response that there is no alternative app available in the App Center for my TS-221 went unanswered.

Therefore this question for the community: Does anybody know of a working alternative antivirus solution for the TS-221 and other models with less than 1.5 GB of RAM?

u could try replace the qts with unraid or other?

you plug in usb flash drive, go to the qnap bios and make sure not to auto boot the default internal usb/dom, then setup the new OS. Then whenever you startup your qnap it will boot from that new OS.

So even if your qnap qts is eol and not updated, you can use the other alternatives that are updated that's one way to go about it.

i've been looking into this for myself as well post eol nas status.


or you can upgrade to a new model for continued qts support


for malware etc, usually if you stay security patched, don't expose nas online, and don't dump files onto nas before checking it's not dodgy (my files usually go through my win10 client pc which uses windows defender, and i'm usually 95% sure these are non dodgy files. anything remotely suspect never gets onto my nas).

thats how i keep my nas clean. I also have backups, so even if the NAS does get compromised, i may have a backup i can revert back to in times of crisis.

the 221 does not have a "Bios"

move the av to the clients (they should have it anyways) or scan remote NAS folders from a client ...
