Ok guys, I suspected when I posted this it would tend to polarize replies between Avast longtime users and newer users. I personally have been using Avast 4 free for a number of years without any problems and was delighted to join this Forum on Avast 5 beta testing. My point was and is simply that it was being rushed into final release too soon, given reported conflicts with Malwarebytes Pro ( me ), PowerDVD, erratic broadband connections / speeds, BSOD's, failing to update virus defs, having to go into safe mode for some actions, not recognizing registration details, fresh install / install over prev version indecision. I personally think it is also unaccceptable to ask users of Avast 5 free to uninstall other previously installed products from other developers to avoid conflicts with Avast, as this seems to me to be a back to front workaround.
