Why would you do this? I’m insider (work in Avast passwords team) so don’t expect suggestions to remove our component 
You, of course can do that, but as we are planning some cool features even for passive users you would miss them without the component.
If you do full cleanup as i described it, then passwords won’t affect your system anyhow. Well ok we have few megabytes memory footprint and our component get few cycles of CPU, so if it is worth for you, feel free follow guide provided by Asyn to remove the component.
Now it is up to you.
