I've been using Avast for years and I'm considering uninstalling it on my Win7 machines. I have several machines that I use for music recording... which needs as few interruptions as possible. (many musicians run machines without -any- AV simply because Norton and so on are so disruptive to recording). But I think the Win7 built-in security seems to work -OK-.
So... if I uninstall Avast, are there any 'gotchas'... files that don't get properly uninstalled and registry entries?
