What to do if Webshield detects a threat?

Another person asked this question about a month ago and it went unanswered, I also couldn’t find anything in the documentation. It’s seems like a silly question, but when it comes to viruses, I want to know FOR SURE that my Mac is protected. Avast gave me the message that the Webshield detected a threat, does this mean it blocked a threat? Do I need to do anything?
