Virus Definition update fails

Hello Wendy,
Thank you for contacting AVG Community Support.
We are sorry to know that. We'll check and help you out.
May I confirm whether it gives any error message? while loading or after.
Awaiting your response.

AVG shows Virus Definition are outdated but every time I click on 'check virus def. updates', it always fails when intalling.  What can I do?
