BSoD "APC_INDEX_MISMATCH (1)"

Hi everybody,
these last weeks I got seven BSoD errors(I got 7 dump-files,which are identical).These problems seem to be related to a bad-running driver as you will see it by yourself.You also have to notice that windows defender told me that there are problems with "[FONT=&quot]C:\Windows\system32\drivers\aswSnx.sys" .[/FONT]
I attached the zip file to my thread ,but I didn't understood how to run a system health report.I tried do retore the systems state to a date before the 22th of january of 2011 but it was too late now.

I got Vista:
-32 bit
-the original installed OS
-OEM
-The computer is nearly two years old.
-I didn't reinstall the OS.
-I haven't installed the SP2 yet.

Thank you in advance for your help .

Welcome
Yes its consistent with the driver
but
the bad news thats not the cause.
That driver is a lead driver and the culprit that is blamed for a bad driver.

May I suggest that you uninstall Avast. Use the uninstall tool
avast! Uninstall Utility
If it still does not work, Ill give you the driver verifier test.

That's not a problem,but what should I use instead of avast?Avira?Kaspersky?Or should I re-install avast after having uninstalled it .

I would go with Microsoft Security Essentials and just for scanning once a week Malwarebytes.

I've uninstalled avast and installed microsoft essentials security instead.I will tell you if I get other BSoD.Thanks a lot!
edit:Ok,i've got patience

Ill be honest, it usually takes a few BSODs to solve the problem. Dont get discouraged. One step at a time.

Hi richc46,
I ran Malwarebytes and was surprised to see that a register key was infected.
I deleted it,as a deleting didn't seem able to cause any trouble on my computer :

Apart of that,i didn't had any more BSoD .
By the way,does Microsoft Security Essentials have a virus-analyse,that you can start before windows runs,like avast?

Very good. Hope that things stay like that.
