Avast Free informs me that my Arris TG2492LG-85 router is vulnerable because of port 7547. Is this a false positive? I did put this to the Avast forum and received a reply indicating two website links which in 2016 explained the cause but not how to resolve it. Thanks.
Hello, thank you for your response. I'm afraid I do not have the experience of delving into technicalities of that depth but my son does so I will show him your response and let him take action. Much obliged to you.
Hello, I ran the GRC ShieldsUP myself, see screenshot, and my son sent a ping with Ping.EU. see screenshot. This was done late last night. Earlier today I prepared the screenshots to publish here. Prior to doing so I did another Avast Free WiFi Inspector scan and Avast reported 'No Vulnerable issues'. Although the three computers here are linked to the same router I carried out a scan on each one using the Avast Free software installed on each one and all reported clean. I am wondering if Avast may have slipped in a slight update and rectified its result if it happened to be a false positive. Regardless, thanks for your input.
Nothing to worry about, move along please. Cable broadband ISP Virgin Media has “taken steps to ensure [port 7547] is no longer discoverable” online after they left it open on some routers. The good news is that this “posed no security risk” to customers, but it remains unclear why it occurred.
