You are replying to a topic that is almost three years old, so the avast program version then would have been avast 4.8 or there about. So would be totally unrelated to the current avast 6.0.x.
Three years - ok, but problem is back.
Yesterday, (02 July, 2011) about 22:15 (local time, CEST) I have closed computer.
Today morning restart was very long and has been ended with blue screen with aswSP.sys problem.
Finally - very big system crash - Windows (XP SP3)logo and hard restart only.
I have RAID and several single hard drives in my computer.
After more than hour of the work I have discovered that currently system may works with RAID and CDROM only.
Connecting another hard drive causes hard reboot several seconds after Windows logo appears.
Last update of my Avast shows date 2011 July 02, 22:47, so I think that was fetched immediatelly after today's morning reboot, just before crash.
I have checked another hard drives NOT previously installed in this computer (maybe trojan or something) - nothing, the same effects with additional drives...
Date of the sign of the aswSP.sys shows 10 may 2011 13:03:43.
Version: 6.0.1125.0
What to do?
Regards
Mariusz
