I need help with turning off selective parts of CIS

Weile using Acronis backup I notice that CIS is really working and also impacts the speed of the Backup. Rather than having CIS scan all the backup data I would prefer to do a scan and then to have CICS turn of all internet access while allowing my local lan to continue to allow me access to the other machines and my NAS for backup.

Is there a way I can do this?

Thanks to all of the great people on these fourms.

Jim
