update...
uninstalled old version, re-installed updated version, inserted licence , fine all looked fine. Avast booted up the old virus definition set, then went in search of the latest virus definitions, it displayed a few different web addresses such as httpgetwinsoc(
http://174...../IAVS4X.....)
then flashed up a few more addresses and then gave up leaving a message similar to : filed deleted= 0 files changed= 0 ..... then last message :
NEWVPS : reloading & the clock spins and keeps spinning indefinately, it is unable to a.) source the latest virus definitions or is unable to reload them.
so basically by upgrading the software as advised the problem still persists, just now it gives you a few more messages.
to an insult to injury, the UK helpline appears to be unmanned. but you do get some very annoying music. i,e customer support = 0
PLEASE AVAST help needed on this, or I simply ask for my licence fee back.
