Avast Continues to Say Netgear Router is Subject to Hacking

This article explains how to resolve the issue if Network Inspector in Avast Antivirus shows one of the following alerts:

Most wireless routers use encryption to protect your Wi-Fi network. Encryption works by securing your network with a password, which keeps out intruders and prevents attackers from eavesdroppng on your online activity.

Refer to the relevant information below according to the message you see after running a Network Inspector scan:

Either one of these issues means that an attacker could eavesdrop on the data that you send and receive over your Wi-Fi network, including your passwords, credit card info, and private messages and photos. Also, an attacker could use your Wi-Fi network to launch additional attacks or commit crimes. If an attack is traced back to your network, you may be liable.

To resolve these issues, enable WPA2 or WPA3 encryption on your router, and all of the devices connected to your Wi-Fi network. WPA3 encryption is the latest and most secure encryption method, but it may not be available on older router models. If your router does not support WPA3 encryption, you can enable WPA2 encryption, which still offers a high level of protection.

Almost all modern routers support at least WPA2 encryption, but if your router does not, we recommend replacing it.

When you enable WPA2 or WPA3 encryption on your router, you also need to set a password to secure your Wi-Fi network. We recommend that you set a strong password by following the guidelines below:

Select your router brand for detailed instructions on how to enable WPA2 or WPA3 encryption:
