Okay I figured out a work around since Avast is taking too long to fix this issue…

  1. go into the application rules then find your plex rules – then delete each rule and then delete the group
  2. then go to TOOLS then FIREWALL then in the lower right corner click SETTINGS
  3. under the default rules section check the box that says “use separate settings…”
  4. under home/low risk zone change the option to ALLOW

So this is a work around… it’s not the most ideal workaround since it does open up some security holes but its better than completely turning off the firewall and leaving your computer exposed
