Virus Defition Updates Block System

Hello John,

We're sorry to hear this.
We suggest you reinstall AVG AntiVirus/AVG Internet Security and check for the status.
Keep us informed here.

I'm using version 21.8.3202, Build 21.8.6586.561
For Virus Definitions they are set to Auto Update.
But every time I go into the Internet the Virus Definitions go through the update process.
This slows down my machine & blocks the changes to other internet sites.
can you please advise how to stop this occurring?
Thanks

Thank you for writing back to us, John.
We've sent you an email instruction for reinstallation.
Please check and revert to us.
