Missed trojan by Norton 360

Norton 360 for Windows
1

I have a Synology DS220+ to which I run a local backup of my Windows 11 tower. When I check the Antivirus Essential log, it shows 2 detections which are quarantined on the NAS: Win.Trojan.Autoit-73 and Win.Trojan.Generic-9907816-0. What’s interesting is that an internet search comes back with limited hits. I also ran an on-demand scan on that folder with Norton, and it showed no problems.

You got virus

3

Um, is Antivirus Essential a Norton product??

4

How are you baking up to the NAS? Using Norton 360 Backup feature or another app? If Norton, the backups are encrypted and could not be scanned by 360.

5

dont now dont think norton 360 can do it i think you need a other program but not sure

6

No. It’s a program on my NAS.

7

I am using Norton Backup. If Norton can’t scan the files, how is Antivirus Essentials on the NAS finding the infections?

8

On conducting another search regarding AV Essentials, it’s based on ClamAV, which has given other users false positives. Some have indicated that various Windows files will trigger the alert. For now, I am going to ignore the logs. Thanks.

The OP has add-on software the Synology has available which is compatible with the OS running on the NAS. Mine offers the same types which I do not use. Antivirus Essential - Add-on Packages | Synology Inc.

You may want to try the scenario below to scan your NAS. No guarantees that it will work since I have not tested this scenario myself:

edit drive scan rename for nas
edit drive scan rename for nas1069×563 67.6 KB

Antivirus Essentials is detecting the viruses in the absence of Norton being able to scan the NAS. The main reasons Norton cannot scan a networked NAS is due to the permissions Windows has built in to protect a network. I would consult with Synology support regarding next steps since that software is proprietary on their side.
