Little Snitch and Webroot conflicts?

I have used Webroot for a number of years and have also used Little Snitch -- seemingly without major issues for a couple of years. The latest iteration of Little Snitch applied new rules to Webroot and blocked the ability of Webroot monitor incoming or outgoing data. In addition, it put a heavy load on my iMac. Has anyone else had this experience?
Once I uninstalled and removed all traces of Little Snitch, Webroot began to work properly again and my computer speeded up considerably.
