Boot time scan won't run on XP Pro SP2.

Hi, after updating Avast Home 4.7 to Build 4.7.1029 on my XP pro SP2 PC, I can no longer do a boot time scan. It starts the Boot scan timer “Press Esc to abort” but instead of scanning starting I get a Error Massage. It disappears too fast to read but here is the last few lines of the aswBoot Log.

InitKeyboard end
GetKey
CKbBuffer::Wait
CKbBuffer::Get
CKbBuffer::Get end
CKbBuffer::Wait end
FreeMemory: 452063232
aswintegInitialize
avworkInitialize
Unhandled exception! Error:17419718
GetErrorText
Unhandled exception Error:0xC0000005 {The instruction at “0x%08lx” referenced memory at “0x%08lx”. The memory could not be “%s”.}

Please see http://forum.avast.com/index.php?topic=29676.msg244143#msg244143

Thanks

I’ve tested avast at boot time into a clean Windows 2000 Professional system (fully updated).

Translating the error message:
Unhandled exception Error:0xC0000005 {The instruction at “0x%08lx” referenced memory at “0x%08lx”. The memory could not be “%s”.}

Their seems to be another problem. The link below explains. igor responded…
