Can't save avast4.ini file

I’m in general not a newbie, but this is awesome.
I tried to chance the avast4.ini file, but I can’t save the file. Or more exact, I can’t even change one bit in the /DATA Folder.
I did check the access rights, stop the virus scanner, stop the Avast! Antivirus services. No Chance. I was also wandering about the read only bit in the data folder. It was on half on. If I uncheck it, it automatically goes back to the previous condition.

I don’t have any more idea what could be wrong!

Use notepad.exe to change avast4.ini.

Or temporarily disable the avast self defense module:

  1. Right click the ‘a’ blue icon on system tray.
  2. Programs settings > Troubleshooting (tab)
  3. Disable self defense module
  4. Edit it.
  5. Enable self defense again.
