Avg internet security

My AVG Internet Security gave me the message "AVG out of date even after manually updating it. On asking for help, I was given a link to follow to repair installation.  After following these instructions,  I still received the same message.  It also said if issue persists it may be due to some old traces and need to reinstall.

Following the reinstall instructions,  I downloaded the removal tool and restarted. It then says to delete the AVG removal tool but I cannot find this on my system. I urgently need to reinstall as my system is exposed and this is my work tool. Please advise urgently.

Thank you
