I just did the update to Comodo Internet Security 3.10.101801.529.
After I rebooted all of my settings were gone! How can I restore these settings? Where can I find the backups? I haven’t exported the settings so is there a way to recover my old settings?
Hello Stephan_
I’m afraid not >:( 
only if you switched to for example Pro Active Security profile then maybe your settings are “there” but otherwise there is no backup of this.
I make it a best practice to export my rules every week, and also before an update in case something goes wrong… which it apparently did for a number of users…
Same thing happened to me Stephan. But, as Ronny advises, I did have a backup.
