Dear Carsa,
I am an Inuit Service Provider, and we have several Intuit Pro Advisors. I literally have hundreds of systems running avast! and QuickBooks with no issues. However, I would apply a Global File Exclusion:
*Intuit* & *.qbw
We have this done in our office for speed, and NOT compatibility!
Sincerely,
J.R. "AutoSandbox Guy" Guthrie
