What features?
All the ones available into avast4.ini file.
I just need a program that:

  1. store the default values (always allow an emergency exit for the user ;D)
  2. read the actual value into avast4.ini file
  3. change it to a new tweaked one
  4. show, like a help text, the comments I’ve posted in that thread.

I know this is possible for almost every value there.
