ESET keeps labeling my router to be a threat!

[ArtisticallyInsane 0]

I literally reset my router last week and changed all the passwords, yet ESET keeps labeling my router as a "threat found" when doing network scanning using network inspector. A message popped up "Network threat found", yet when I click on it, it's my router and ESET doesn't specify the problem and everything seems to be okay.

1. The router have been reset last week.

2. The main password have been changed to a very strong one for both account and WiFi passwords.

3. Checked the DNS addresses, nothing seems to be out of ordinary.

4. Checked the connected devices, all belonged to me.

5. Checked the MAC filtering, all were my devices.
