can webroot and constant guard protection from comcast be on at the same time or not a good idea

Hello and Welcome to the Webroot Community Forum,
 
Yes you can run Guard Protection but IMO it's unneccesary because Webroot you can run it and leave it without bogging down your system with added programs. Webroot does it's job protecting in many ways.
 
Here's more info about WSA's Idenitiy Shield and it's awesome http://www.webroot.com/En_US/SecureAnywhere/PC/WSA_PC_Help.htm#C6_IDProtection/CH6a_ManagingID.htm
 
 

 
 
Please have a look here about Webroot and third party AVs compatibility https://community.webroot.com/t5/Webroot-SecureAnywhere-Complete/Incompatibility-Messages-Regarding-Webroot-from-Third-Party/ta-p/20338
 
Instead of me saying anything it's best to read it for yourself what the potential Webroot has the Webroot WIN Cloud  that does all the work not your PC: http://www.brightcloud.com/platform/webroot-intelligence-network.php
 
 

 
As for your bluetooth device I don't think Webroot is blocking this but you can check here on the PC User Guide, and look here.
 
Check the Bluetooth manufacturing website for information or maybe you need an updated driver.
 
I hope I covered everything for you and if you still have issues then feel free to ask and if you need more help you can always  t issue a Support Ticket free of charge with an active subscription.
