Forgot to mention, during install of the latest Avast6 free from
file hippo it gets to the stage of "finishing setup" and sticks there
with the full green download bar and does'nt progress any further.
Then as soon as i click the mouse the pc freezes,and i have to turn it
off at the power switch and back on then "start windows normally".
Then when windows boots up the voice comes on saying Avast has been installed.
Also a neighbour asked me to put Avast on his pc and it did exactly the same thing.
