avast says new network detected

Avast and some other antiviruses are fond of causing network connection issues. Many users complain about a problem where Avast says a new network is detected while connecting to a recent one.

Also, users complain about getting a stable antivirus for router protection on their devices.


Why does Avast keep detecting my network as new?

Avast detecting a recent network as a new one can occur for many reasons that vary from issues with the antivirus software and your PC. The most common reason is outdated Avast antivirus software on your PC. It can cause the app to malfunction and result in issues.

Furthermore, Avast can affect your network connection due to other factors, such as:

  • Avast firewall interference The network issue can occur due to the interference of the Avast firewall, prompting you to reconnect to an old network as a new one. Also, the firewall can override previous connections for some reason. Check how to allow programs through the firewall here.
  • Issues with the network The router network you’re connected to may be faulty or corrupt, so Avast can override the previous connection and show it as a new one. So, a compromised driver can cause it.
  • Virus and malware Avast can say a new network is detected when you have an old network because of virus and malware activities on your device. It can affect your device’s performance and prompt some issues with Avast.
