AVG stopping file transfer with Mailchimp

Hello Dave.
Thank you for contacting AVG Community Support.
We are really sorry to know this. We'll certainly check and help you out.
Do you notice any error message pop-ups from AVG while initiating a file transfer?

As you strongly believe AVG to be the cause, please check to disable AVG completely and check the file transfer. To temporarily disable AVG refer the article | AVG (https://support.avg.com/SupportArticleView?l=en&urlName=disable-avg-antivirus&q=disable&supportType=home)
Please disable and let us know if the file transfer went hassle-free.
Awaiting your response.

The issue with AVG feels like winning the lottery (http://www.jhatkalottery.in) - limiting file transfer and causing website log-offs. Seeking directions to resolve this.
