AVG Updates Stopped

Hello Gary,
We regret the inconvenience caused. To resolve the issue, we suggest you to remove AVG traces using AVG remover tool( http://aa-download.avg.com/filedir/util/AVG_Remover.exe ). Please restart to complete the uninstalling process. After running AVG Remover, you may need to manually uninstall any remaining AVG applications and also 'search' for a folder "AVG Remover"(usually in 'C' drive) and please delete it manually. And then I request you to install your program 'AVG Protection' by following the instructions in http://avgread.me/1FKGRZI and let us know the status. Thank you.

Hi I have noticed that my AVG updates stopped coming through on the 17th March and that I now every time I boot up have to engage the firewall manually as it is always down when starting up from cold.  I did have a web browser threat that has been removed by the microsoft security essentials tool but also I cannot uninstall avg as it stops stating that i do not have the priviileges to continue the uninstall. I think that the web browser threat has done something and need advice on how to either delete avg and re boot or do I need to do something  else. Advice would be very much appreciated. BTW pc works fine and have seen no issues on a day to day basis its just manual firewall.
