I always had avast free in my computer with Win XP SP3 and never had a problem. Since last update for version 5.1889 my computer crashs after reboot.
I have already unistalled it by control panel, avast unistall tool, using safe mode… When unistalled, everything works fine, but after reinstall, it crashes again.
What do you suggest? Downgrade to an earlier version?
Ok… Seems the problem is that ZA is not allowing avast.setup correctly or is blocking any avast component. Maybe removing all avast entries from ZA and boot. On questions, allow full avast connection next time.
I had the same problem with v5.1.889 on XP. See my post about the problem here and how I installed a previous version to get around the problem until Avast is fixed. http://forum.avast.com/index.php?topic=70100.0
