Email shield causing DNS errors?

Hello Greg,
Let's have a look at it together. Please share the screenshot http://support.avg.com/SupportArticleView?urlname=How-to-create-a-screenshot of error message you received when Email shield is turned on.

My laptop is running AVG Internet Security (subscription version) on Windows 10. It recently started suffering intermittent DNS errors; after some trial and error, it appears that Email Shield is causing them. They stop when it's turned off; resume as soon as it's turned back on. Is there a fix for this? I've reset winsock.
