Title: Your network router is accessible from the Internet.
Post by: REDACTED on May 29, 2016, 08:11:18 PM

Hello!.  :)

At first I installed Avast Free (Windows 7), but I wanted to know how effective the Avast Premier. So I installed it on my computer and gave me 30 days trial. But since I updated my Windows 7 to Windows 10, the Avast Premier generates this alert in: home network security. Your network router is accessible from the Internet.  >:(

Please, I would like someone to help me. For your attention, thank you very much.  :D

A button on the router doesn't change the default password.

Some options on why that message can show :
- Router OS is has a weak password
- Router is vulnerable for 0-rom
- If the router is provided by a ISP they can have a back-door installed

Best thing to do is to flash the routers firmware with the latest version from the manufacturer and check again.

Hello Pablinni,

This message means, that your device is accessible from the internet. Meaning that anyone can connect to it.
It is caused by some open ports on your device.
Since you recently updated to Win 10, it is most likely port 80 on your computer. Win 10 have sometimes IIS (web server) enabled and running by default.
Guide on how to uninstall IIS (if you are not hosting any websites on your PC, you don't need it): https://technet.microsoft.com/en-us/library/cc779925(v=ws.10).aspx

The message is saying, that your router is accessible from outside, but is displayed on your PC. Not on your router in the Network Scan results.
This is a mistake on Avast's side. It should be saying "your PC" not "your router".
We will fix the message to be more accurate.

Thank you for reporting this,
Filip

Thanks for the answers. Because of my limited time, it had failed to point out that the problem was the ISP router. I schedule a visit to the technician my ISP, and I said the router was bad. It failed by normal use. My conclusion is. Thanks to Avast, and its "Home Network Security" who told me that my router was unsafe.  ;D
