Actually amacd55, it doesn't make a difference. I wondered that too.
I've discovered that "Actual URL=3" is simply the default setting - so it shows the grisoft.com site first on the drop down list within AVG.
You can choose to set it to 4 for download.grisoft.cz, 2 for the ftp site - I'm sure you get the general drift as to how it works...
Anyhoo, all this can be changed outside of the .ini file simply by choosing the preferred default download location from the drop down and then hitting 'Apply'.
This I have learned simply by experiment.
Now let's hold our breath and see how long it lasts....
