Cannot delete "SandBlastBackup" folders

I installed ZoneAlarm Free firewall recently. I thought I was getting a firewall only; but, it appears something else got installed along with it.

I am finding folders named "SandBlastBackup" that resist deletion. The existence of these sub-folders are interfering with the my automated backup and cleanup routines.

How can I delete them?

Short of doing away with ZoneAlarm's free firewall, how can I prevent the SandBlastBackup folders from being created?

I have closed ZoneAlarm and stopped related processes and I am at the limit of my knowledge of this.

 

The problem is in the deletion of the oldest folder as a new one is created. SandBlast blocks the deletion of the parent folder and all sub folders and sub-subs and sub-sub-subs, etc. In other words, one SandBlastBackup at any depth prevents the deletion of the parent. Right now, the only way I can delete one is individually, one at a time with a program called Unlocker.

The backup routine is one I invented myself and have been using for nearly twenty years. It works smoothly and has never failed. I'll get rid of ZoneAlarm before it.

Do you know of a firewall as configurable and as easy to use as ZoneAlarm?

 

The thing I like about ZoneAlarm is I can very easily set it to ask permission on everything and gives me full control over what can communicate with the internet.
