Don't copy it into run, just double click it, to run it.
I assume you were able to find it in the avast4 folder ?
1. When you find the avast4.ini file, "C:\Program Files\Alwil Software\Avast4\DATA\avast4.ini" if installed in the default location, open it with notepad.
2. Find the section starting with [UserInterface].
3. Is there a line that starts with StartWithSkin= in that section (before the next section name [ section name ]), if so change the value to 0.
4. If there is no line beginning with StartWithSkin= create a new line and type the following StartWithSkin=0 (ensure it is between the section names [ ].
5. File Save, the avast self-defence with ask if this is OK answer Yes.
That should be you done.
