I have lost tract for the last 3 days the updater on both my pc’s don’t work,and i have been doing it manualy
If you have done it manually then it is likely to be up to date, but I suggest that you bookmark this page, http://www.avast.com/virus-update-history and this shows 17.2.2013 - 130217-0 is the latest.
However, there have been times when this isn’t fully up to date, even though it is meant to happen automatically when the update is released.
