Subject says it all. I am trying to update the database on my laptop but when I download and install “Avast VPS update for versions 5 to 8” from the https://www.avast.com/en-us/download-update page, it says that the update is from 03/04/2018. It was my understanding that these database updates where done daily and I have never had an issue in the past until now.
I first saw the issue Yesterday and was going to see if it got fixed with today update but I have not seen a change in the last 24 hours.
They are done daily and often more frequently (see image, shows 5 VPS updates today on my system), but the download update page you reference is for off-line VPS Update and contains the complete database.
If that system is on-line then you should be able to do a manual VPS update from the avastUI
Thank you for reporting this. Some forgotten http redirect caused that iavs5x/vspupd.exe pointed to old origin server. We apologize for inconveniences caused.
