Downloads failed

I have recently purchased another computer after loading AVG Internet Security & Tune Up Every Microsoft update has failed to install If I remove AVG they can be installed. 
Any suggestions as to remedy.

Hello John,
I'm sorry to hear about this. I request you to disable AVG component (Open AVG Internet Security > menu > settings > components) one by one and check which AVG component is blocking your Microsoft updates. I also request you to change AVG Firewall network profile to private (open AVG Internet Security > menu > settings > components > firewall > customize > network profile > change all the network public to private), please go to Firewall customize settings again > scroll down > click on system rules > enable all the system rules if it's not configured, please click OK and check if you can access all the websites/Microsoft updates with enabled AVG Internet Security.
Best regards,
Alok.
