"A Quiet Worker..."
It does an acceptable job: especially as a free program. I run Vista Ultimate and haven't had a problem since installing Avast Free. I came to Avast from AVG Free and, much as I've used AVG for several years, I like Avast a little better.
If anything, it's the voice which announces that the database has been updated! When I've got the volume up for music or games it can 'scare the pants off me'.
