Streaming information like this can fall foul as it doesn’t strictly use HTTP protocol and the use of JAVA to could be the reason.
The web shield redirects all http traffic so that it can be scanned, but it is expecting the traffic to be using HTTP Protocol.
You can add the IP address of the Scottrade site so that it doesn’t get redirected.
From the avastUI > Settings > Troubleshooting - scroll down and expand the Redirect Settings > WEB > Ignored addresses: and add the IP address.
Obviously there is a limited risk in ignoring the site - given that it uses JAVA, which could be exploited.
