avast hates itunes?

problem is simple… Ive used avast free version for a long time. I was actually considering upgrading, but last week I got the 2015 update and now my Itunes store is blocked. I have all the suggested ports exempted, my windows is up to date, itunes is up to date.

if I deactivate Avast shields, I can access the store just fine. Before I did the update to the latest version, avast had no problems with itunes store, now it does.

with avast shields active, if I access the itunes store I get the message “we could not complete your itunes store request, An unknown error occured (-3212)”

if I disable avast shields I can access the store just fine.

The old version before update did not have this problem.

I have win 7 home premium version 6.1 SP1 (64 bit)
avast free antivirus 2015
itunes 12

What shield is causing the problem?
Disable them one at a time to find out.
