For the last few months, every time a launch HitmanPro to scan my XP 32bit system, I get a BSOD within just a few seconds. It appears that the cause may be the atapi.sys driver -- and ntoskrnl.exe may be involved as well. Interestingly, HMP is the only program that ever causes this BSOD problem. And even more interesting is that if I run HMP in Shadow Mode (Shadow Defender), it runs fine -- no problem at all. Any thought or suggestions??
