I'm running a program on Windows 10 called Calibre which is a very good ebook manager. However, since a recent Webroot update, Calibre will no longer start properly without being run as Adminstrator which causes otherfunctional  issues. 

 

When I debug what's going on, it appears that Webroot is not allowing the main exetuable to open up a socket to a worker  process:

Disabling all of the shields does not fix this probelm, nor did adding every exectuble in the "Calibre2" folder to the whitelist (where' s folder whitelisting on the Home edition when you need it?). So I am both stumped and frustrated.

 

Short of uninstalling Webroot (my next step), can anyone offer some suggestions on why Webroot is injecting istelf into this process and how to override. If I can't make this work, it's off to another A/V since this is an app I use a lot anf have being doing so for years. I can replace the A/V but not the app.
