Virus definitions

Hello, Rjm.
Please accept my apologies for the inconvenience this may have caused. Please try to run repair installation of AVG as suggested in this link http://support.avg.com/SupportArticleView?urlname=How-to-repair-AVG to check if that resolves the issue.

double click on AVG Internet Security icon:
screen appears with
* at the top:
        message: "the virus definitions have expired" and in addition a block with "update"

* in the middle 5 blocks with side by side:
        basic protection => "computer" and "web and e-mail"
        full protection => "hacker attacks", "privacy" and "payment"

* at the bottom of the screen:
        "last computer scan: 5 hours ago"
        "computer scanning"
        "virus definition: 4 hours ago"
 
When I click on the top of the "update virus definitions" block, a new screen with 4 updates will appear, namely:

* engine and definitions => update => up-to-date: current version 180123-2
* program => update => up-to-date: current version 17.9.3040
 
clicking on OK returns to the original AVG screen with the recurring message "the virus definitions have expired" or updating the 4 elements has not produced the desired result.

 
QUESTION: How do I realize ... step by step ... an effective update of the expired virus definitions?
 
STARTING POINT: I ​​am fully protected by AVG:
basic protection => "computer" and "web and e-mail"
full protection => "hacker attacks", "privacy" and "payment"

 
my thanks for the help !!
