Avast 2014 Internet Security, Windows Vista Home premium , I’m experiencing problems with freezes consistently when attempting to use the “sandbox or the safe-zone”. Most times I get an error message stating that the Shock-wave plug-in is not responding and then I’m prompted to continue with plug-in or stop plug-in,…either way, the machine freezes and a manual shutdown/reboot is needed to recover. You-tube videos cannot be played at all without freezing in these modes. This problem did not begin until the update. If sandbox and safe zone is avoided, avast 2014 works fine.
