The Teramind Agent, when installed, injects a customized HTTPS certificate called Quick Web Proxy (on Mac it's called, "Internet Widgits Pty Ltd.") that allows it to decode encrypted data so that it can monitor HTTPS sessions and other secure web activities such as webmail, IM chats, etc. If this certificate isn't installed correctly, then monitoring for those items may not work properly.
