AVG internet security - unlimited

When I open AVG it says it's out of date and should be updated.  When I do this, it says it is up to date, but I keep getting same error message every time.  The version is 17.5.3022.   I have tried to do several "repairs" and restarted my computer but nothing works.  Any suggestions?

Hello Cathie,

I am sorry to know that.
The message appearing as out of date on AVG user interface is a known issue and to fix it, we have to completely reinstall program once.
Please uninstall AVG Internet Security from control panel as mentioned in this article: http://avgread.me/1DEtNP0 .
