Most probably. It seems to be a VPS update (virus database) and not all the program.

If you set ‘Automatic’ when you saw the window, avast is already updated! 8)
No, you do not have to uninstall the previous version to install a new one. Just automatic, just incremental and fast 8)

With ‘Manual’ you will need to ask for updates and won’t receive any warning from the program. Again, do not have to uninstall. :wink:
