Adding to what Petrovic said, I checked the website for the software using Brightcloud.com, which is Webroot's URL checking system.  It returns a result as follows:
 
High Risk: Botnets and Proxies found.
 
If you believe this report is in error, please submit a Trouble Ticket to have Webroot Support take another look, but it does appear that this is rightly considered to be a high risk software and blocked accordingly.
