After setting my computer (XP Home) to not automatically reboot at BSOD, I noticed that Perfect Disk 5 and 6 would kill my computer and I got the message on the BSOD that it was the driver aswMon2.sys that was conflicting with the defrag software.
After disabeling Avast 4 Pro and trying to run perfect disk again it works fine but not while Avast is on and running.
Is there a fix in the works for this problem, I like Perfect Disk almost as much as Avast but one of them as to go.
