This is a follow up on 4.8/5.0 with the advise received here from Team Avast/DavidR a memory issue was discovered,not really an Avast problem, after several exchanges links were supplied and with fine folks at Crucial/Micron in Boise, I received and installed a 1 GB memory stick, my machine is running better than ever, I felt it necessary to at least recommend too anyone who is considering Avast or Crucial products both are fine products and work as advertised, and this forum is great !
