Norton Family Affects General Internet Access?

I've started getting browser timeouts when browsing websites and I've found that using Task Manager to close Norton Family (NF) allows me to access websites again (ordinary websites like Home Depot).  I do not have blocked websites in NF so NF is not blocking my access on purpose.  I'm using Chrome on Windows 8.1.  This is starting to make NF unusable for me as all of a sudden I will lose network access until I either close NF or wait and some random time later access is restored.  This seems to be happening in a random fashion - things are going fine and then I lose access.  Any ideas on how to fix this?
