Hi!
I had this issue with Avast newest beta and today I decided to give AVG a try. However, the issue is the same:
With AVG installed on HOST PC, my VMware 12.5.2 build-4638234 virtual Windows 8.1 x64 is stuttering everywhere. Host Windows 8.1 itself is fine.
Does not matter if I open a program or simple Explorer on VM W8.1, still there's noticeable stutter in the process.
See video example:

Uninstalling AVG/Avast beta solves the issue for me + I do not experience it with latest Avast stable release. So it's definitely the beta software that is causing this.
If it matters, I have Glasswall + Zemana AntiLogger latest versions on Host machine. i5-750, 12GB RAM (VM has 2 cores and 2GB RAM).
EDITED.
HOST = My PC/actual Windows.
VM = Virtual machine set up in VMware.
