Webroot says threat but cant remove it

After a full scan webroot highlights a threat and when I move to the next step to remove it I get a screen that says it can't remove it.  I've tried in Safe Mode with same results.  I've rebooted, etc, with same results.
 
The other interesting thing is that when I look at the threat log it says that no threats have ever been detected.  I'm not sure whether I really have a threat or not?
 
The 'dashboard' shows active threat and after a scan it displays one threat removed.
