I know, perhaps not the safest option, however, to stay with Norton I have no choice! So I use NAV 21.7.0.11 for two legacy computers with SSE only CPUs. Until recently, I had no problems to get updates automatically and via LU.
However, now I can't update the NAV Virus and IPS definitions:
I did a clean reinstall of NAV 21.7.0.11, but, no change. Besides, the problem happens on both the legacy computers, so it's not a single incident. As I have done in the past, I went here to download a full size offline definition file:

Regrettably, all recent files fail to update. I had to go back to 20170124-001-v5i32.exe to be successful. What's up? Any ideas? Remember, updating to NAV 22.x.x is not an option as for that I need SSE2 based CPUs. Thanks.
