can the router settings be changed by virus? If it is secured by ISP

Boggin:
I'm not sure why yours changed from Home to Public - mine has done that before, but you are right in that a Home Group is sharing between computers in the home environment.

While at home, the Home setting should be fine.

Hi,  samson,How can i disable the wifi, when i do not want it. It is the question. Avast confirmed that the router is affected with Rom  vulnerability, which it says that it prevents from ROM memory to totally erase when RAM has to cease to exist, when powering off.
                    i followed the instruction to trial vpn, by them. But it has not resolved my issue, instead downloaded their sub softwares to the phone.
                    I went to the LInk by samson, which i think that it goes to the check page of avast check on my router page. It also lists the vulnerability and it says to update firmware  or contact ISP.
                     Hi, boggins.
                     If the router is affected, it means the modem of the particular person is affected. Is it correct , pl confirm.
                     Or if the router is affected that it affects all the router pages of the service provider
                     Actually we are least bothered about problems in secured connection, but when this sort of sudden change of internet access to nil, we have to think of getting rid of so called wifi attacks.

Hi, Samson,
               This is the Details in that page
We have identified the following problems with your router:

ROM-0
Severity: High

This vulnerability allows an attacker to easily gain control of the router and therefore your Internet connection. The attacker can use a specially crafted HTTP request to download all important and secret data stored in your router -- your router login/password combination, your Wi-Fi password and your configuration data.

To overcome this vulnerability, aside from applying the firmware update that addresses the issue, there is one more technique that can be used: setting up port forwarding for port 80 on the router to an unused IP address on your network. To do that, enter your router configuration page and find the "Port forwarding" section. Here, set up a rule that tells the router to send all http traffic to an unused local IP address (for example 192.168.0.255, if this address is not used by any other device on the network).
                           I wish to bring to your notice the ONe more technique, which says change the port settings of 80 to some numbers if this address is not used by any other device on the network. Ok, can i do that in router settings.
                            Pl clarify, that it is the ultimate control of the service provider or the user. How to know the device used by the said ip address. pl educate

I'm not sure about that - you could disconnect the router and wire directly to the modem and see what Avast reports then.

If you log into the router, there may be a manual wireless settings page where you can uncheck the box for Wireless, but your ISP will be better able to advise on this, but you should contact them anyway and report the infection and they may send you out another router with upgraded firmware.

hi, so you mean the router is nothing but my modem. So it gives the settings inside the modem. Avast report that in his android phone, but of course, in the link Samson gave.
    But i have panda antivirus and malware bytes, which i think they never touch router.
     Eset online scanner is also not touching the router.
