Ashsimpl invalid page faults

[Spook]

I have Win98 and installed Home Edition Avast 4.  Resident checking works fine. But I have a problem with Ashsimpl.exe causing invalid page fault when I try to open Scanner.  If I leave the Error Dialog shown, I can still use Avast without crashing but closing the Error Dialog kill Avast.

This also happens after scanning Hard Drive, but does not occur after scanning Floppies  

If I don't get the Error Dialog when I start the scanner, I will get it if I scan a Hard Disk - so sometimes it starts O.K. (no error) but always shows after scanning (successfully) a Hard Disk.

Any thoughts and help appreciated  

Here's the Error:

ASHSIMPL caused an invalid page fault in

Thank you very much, Vlk, for your fast response (only about 1 hour - excellent!).  I tried your "trick" and it stops Ashsimpl from Invalid Page Faulting - BRILLIANT  

Unfortunately the "trick" stops Avast from scanning "Selected Folders".  By that I mean that Avast always scans my Hard Drive beginning at the C: drive and continuing to my last partition (G: drive).

However, I will continue to fiddle with it because your "trick" made such an impact.  I will try and find out what ODBC has to do with the problem (it is early morning here and I am zonked   )

I also tried to narrow down the fault a bit - test results are below.  I will narrow it down to be more specific (exe, dll, txt, etc.) - later  

Thanks again Vlk!  Your help was inspirational  

Settings: Resident Scan OFF, QuickScan, Selected Folders.
