I've been using ZA Free and iDrive together for months, and they played nicely. A few days ago, I updated to the latest ZA Free at about the same time as I updated to the latest iDrive.
Since then, ZA keeps complaining about iDrive: "IDrive Service was prevented from changing the behavior of ZoneAlarm Free Firewall by modifying" three files:
iDrive pointed me to a web page that instructs me to configure some permissions manually and add some IPs, which I have done, to no effect.
I appear to be stuck, permanently, with ZA warnings in the lower right corner of my monitor.
So... any idea what next? I should add that I got iDrive separately and apart from any ZA offer, but I can't see how that would make a difference.
