Every time I use smart scan my modem restart

[REDACTED]

I'm certain they will report back.  Be patient.

Ok, I will. I also hope this info helps: I tried to use the wifi scan with my phone (avast free version) and the router didn't reboot at all, don't know if the pc and android version are similar though.

So something weird happened today, i restored my pc and modem to factory default and downloaded chrome avast again, later a popup said avast deleted an infected archive, I dont remember the name but i searched about it and it was a samsung config archive. After that I tried the WiFi scan and the router didnt reboot with the internet cable, but it still reboot wireless.

I guess the infected archive was a false positive?

Any news from avast support?

Hello Luan28,

Thank you for the logs.
We will investigate the issue.

Hello Filip
Do you have any idea what the problem is already?
Thank you!!

Hello Luan28,

Unfortunately not, we didn't find anything out of ordinary in the network scan. It finished successfully - no network error (router restart occurred during the scan).
Does the issue occur when you turn off the Network part of Smart Scan?
You can turn it off in Settings > General > Smart Scan
If yes, please try turning the other part one by one and let us know which was the issue.
If not, please run the full network scan (from Wi-Fi inspector page) - does the router restart after running the full scan? If yes, please generate a support package after running the full scan.

I apologize for the long response time.
Thank you for your help and patience.

Yes, it only occurs if I enable router scan in the smart scan or if I run WiFi scan. I'll send the support file later today, and I also contacted my router support to try updating my firmware but they said there's only this firmware available for my model. I'd like to know if it could possible have any relation with virus? I already reset my modem and pc to factory defaults, so I think it's not the case.

Thank you and I'll reply later with the support package.

I also noticed in some pages here the https lock is missing, I don't think it happens in other sites though. I was worried my router could be hijacked.

(this is not the rebooting router, I found no problem running the wifi scan on this one except for a unknown device I think it's my cousin's tablet or tv https://forum.avast.com/index.php?topic=204059.0)

I doubt that that is the only firmware available unless it is a brand new model there normally is always older firmware.

There happen to be a disributeur of Zyxel (Valadis) in my town and I know someone who works/worked there.
Haven't spoken to him for a while, but I'm gonna give it a try.

They said it was a special router made for my isp, and it was the only firmware created so far. But I'd be glad if you coule speak to him.
About the dns problem I'd like to know from you guys if it could be being hijacked because I'm really worried since I used my credit card so many times, and there was that "problem" with this site https lock.
I've sent my current router config, it's in portuguese but I think you can see if is anything weird.

Thank you again!!

I've mailed him so let's hope that I get a answer.

It does indeed seems to be a router that was made for your ISP, but it very well can be that firmware for another one will work.

[Eddy]

Got answer back and the firmware for that router is solely made for your ISP.

You could contact Zyxel in the USA, but I doubt they will have other firmware.
