Avast blue screen of death - Atapi.sys error

Avast blue screen of death. >:(

I get an Atapi.sys blue screen error and need to reboot. It happens when update notification occurs. ???

Check to see if there is a file in C:\Windows\Minidump If there is then Upload it to ftp.avast.com/incoming/

I cannot find the folder … ???

Here is additional information on how to invoke a memory dump file: http://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=71.

Please, zip and upload the C:\Windows\Memory.dmp file to this anonymous ftp server and name it uniquely: ftp.avast.com/incoming. Avast will analyze it and respond back to you in this thread or to your email.

Please let us know if you have any additional questions. Thank you.
