Avast Free Antivirus definitions not updating
« on: May 16, 2020, 12:44:17 PM »
For at least the last 3 days, the latest free version of Avast Antivirus hasn't been able to connect and successfully update the virus definitions, on Windows 10 Home v 1903.

Do you have any advice or information that can solve this or shed light on the issue?

I cannot see another recent thread on this topic, but your search function shows so many returns and so cluttered, I apologise if this is in the wrong place\already been asked.

So it might be on their end? I've seen older posts where they admit that, so I guess it's possible; it'd be a relief to know, so I don't have to go hunting down obscure potential issues....

Make sure Avast isn't blocked by your firewall and try again.

No, it wasn't the firewall, though I've got sick of that for blocking other things; instead I've moved to a complete internet security package
