Stuart,
Not to worry, re-installation of AVG Internet Security will fix this error. Go to Control Panel -> Programs and Features -> Uninstall -> Uninstall AVG Internet Security and restart your device.
Click on this link: http://files-download.avg.com/inst/mp/Internet_Security_1824.exe to install AVG Internet Security. Once the installation gets completed, open Internet Security -> My AVG -> My Subscription -> enter your license number to activate your product. We are here if you need further help.
Stuart, I'm glad to hear that the issue has been fixed. You might have contacted our Paid AVG GO technical support. Feel free to contact us again if you need any further assistance.
Best regards,
Alok.
