Title: BSOD avastsvc.exe & aswmonflt.sys
Post by: Mordeen on May 04, 2012, 11:39:13 PM
Sorry if this is a double-post, but I got an error in the forums on the first try.

Anyway, I have a Gateway FX7026 with a clean install of Windows 7 Pro 64-bit, with Avast Home Free, CCleaner, Malwarebytes Free, Office 2007 Enterprise, and league of Legends. Three days in to the new install, and I get a BSOD, for which the windbg crash analysis is pasted below. Any help on the cause/solution would be fantastic. Thanks in advance!

An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arg1: 0000000000000002, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000001, bitfield :
   bit 0 : value 0 = read operation, 1 = write operation
   bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80002efe932, address which referenced memory

Debugging Details:

WRITE_ADDRESS: GetPointerFromAddress: unable to read from fffff800030ff100

Hi Mordeen,

I'm just a forum member, But I'm going to give you some suggestions.

First things first, Is Avast and the Operating system fully updated?

Can you reproduce this error? for example does it happen when you do something specific?

Try disabling the the sandbox, if the BSOD still occurs switch it back on.

Then try disabling Shields one by one to see if one of them are at fault.

How often does this BSOD error occur?
