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.

and they will be happy to sort it out for you and the new version of Little Snitch just might need to be Whitelisted in the Webroot Database!
