I'm running Mac OSX. when I ran
sudo lsof -i -P | grep -i "listen"

I'm getting all these processes, is it normal?

This seems to be normal behaviour - Avast uses local proxies for some of its services (e.g. Web Shield and Internet Mail).

For example, if you're browsing through the web, the data you download from webservers will be analyzed by Web Shield before it is transferred to your browser.

For more details, you may also ask in the community forum.

PS: On my computer (Windows OS) there are also a few listening ports belonging to avasts process.
