I don't think so, if it's not related to malware....and a review of your HJT log doesn't show anything to me that is malware related...but Vista is a new system (relatively).

werfault.exe, to my understanding is the Windows Vista error reporting system, equivalent to the dwwin.exe system of XP.

I found this:
Application crash handling is also improved in Windows Vista. On previous versions of Windows, when an application crashed it executed an unhandled exception handler. The handler launched the Microsoft Ap­pli­cation Error Reporting (AER) process (%Systemroot%\System32\Dwwin.exe) to display a dialog indicating that the program has crashed and asking whether you wanted to send an error report to Microsoft. However, if the stack of the process's main thread was corrupted during the crash, the unhandled exception handler crashed when it executed, resulting in termination of the process by the kernel, the instant disappearance of the program's windows, and no error reporting dialog.

Windows Vista moves error handling out of the context of the crashing process into to a new service, Windows Error Reporting (WER). This service is implemented by a DLL (%Sys­temroot%\System32\Wersvc.dll) inside a Service Hosting process. When an application crashes, it still executes an unhandled exception handler, but that handler sends a message to the WER service and the service launches the WER Fault Reporting process (%Systemroot%\System32\Werfault.exe) to display the error reporting dialog. If the stack is corrupted and the unhandled exception handler crashes, the handler executes again and crashes again, eventually consuming all the thread's stack (scratch memory area), at which point the kernel steps in and sends the crash notification message to the service.

Here: http://www.microsoft.com/technet/techne ... staKernel/

It sounds like some application crashed on your system...does the werfault.exe dialog box tell you which application is having/creating the problem?

I use Windows Vista too...but readily admit that I am no Vista 'expert', however I will contact the available resources at this site to help if required. If you can identify the application that caused the problem, you may have a better chance of finding a solution on the Windows Vista boards found here: http://windowshelp.microsoft.com/Window ... fault.mspx

Identifying the application causing the error message might lead to a potential solution. I know with Vista from first hand experience that it may as simple as updating a driver or reinstalling a corrupt program...it's happened to me a few times already.

I think I got it. I was having trouble opening anything to adjust error reporting settings, but when I restarted I was able to turn error reporting off before getting any crashes. Then I restarted and turned error reporting back on and no problems thus far. Thanks for your help, and I'll let you know if it happens anymore.
