I have been using avast for many years now and I updated recently to Avast 8. Now I am getting a message that avast is outdated!!! Please help! I have attached the pic of it(Action Centre, Windows 7 Ultimate 64 bit).
That’s a Windows problem. Has been there since the XP days if you Google “repository”. Try a couple of reboots. Also is your system clock and date on the right time? If all those do not soleve .the issue then do a complete uninstall and reinstall of Avast. Use the Avast uninstaller.
