Pls remove(uninstalled) zone alarm and reboot the system and do a clean install of Avast! and report back.

Thanks to@ bob3160

Not only remove ZoneAlarm through control panel, but also use the removal tool which can be found through : http://www.ache.nl

Hi,
many thanks for your advice, guys. i since discovered that aswsqlt.dll was corrupted & still in directory even after uninstalled. so i just manually deleted it. after reinstalled with new copy of aswsqlt.dll, avast is up & running.
have a good day,
binh
