Hi thanks for your interest,
Yes I did restart my PC after the Avast Free Antivirus program update. I also reinstalled the Avast update to no avail.
I do not recall going to settings in Avast Free antivirus since I changed NordVPN from UDP to use Nordlynx servers (only a few days ago) so I cannot advise whether the "You are Offline" issue existed with the previous version of Avast Free Antivirus prior to the latest update yesterday.
I HAVE however done a little testing and as an experiment reverted to using a NordVPN UDP server (as before) and I noted after a PC reboot that Avast Free Antivirus does NOT show the Offline message.
I then reset NordVPN to use a NordLynx server again and restarted my PC and Avast Free Antivirus is again saying "I'm offline" although its working perfectly and knows I am online.
This suggests to me that whilst Avast Free antivirus (as far as I can tell) works perfectly with NordVPN's NordLynx servers (wireguard protocol) being used it is FALSELY reporting "You are offline".
Regards
