Slow Lan Network speed : Paid Avast Internet Security 2

I have followed the instructions in the original post and wanted to know if this issue has been resolved. I am also transferring files from a local drive to a mapped network drive at 1GB/s when avast is installed that goes down to 100 - 300Mb/s that is insane
even when adding the mapped drives and source location to the exceptions list it changes nothing

I am unsure if i have posted in the wrong area for this issue but it seems a shame that after nearly 2 weeks there has been no response

  • Which Avast…? (Free/Pro/IS/Premium)
  • Which version/build of Avast…?
  • OS…? (32/64 Bit…? - which SP/Build…?)
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

-Avast Premium Security
-20.2.2401 (build 20.2.5130.568)
-Windows 10 64 Bit 18363 then updated to latest still the same

  • No other security Software installed
    -Have used avast for 10 years+ no other AV software

Elaborate.
