BSOD after installing Avast

Hi. If my wife installs avast internet security (the one available for download) that she bought, she gets BSOD. Its pretty obvious that its the antivitus thats causing it because if i uninstall it, it works fine - and then reinstalling results in BSOD. Atheros wifi drivers are updated.

I upped the minidump files to your FTP:

ftp> put minidump.rar
200 PORT command successful. Consider using PASV.
150 Ok to send data.
##################################
226 File receive OK.
ftp: 71436 bytes sent in 1,43Seconds 49,85Kbytes/sec

Hard to say from minidump, can you please compress (rar/7zip/zip) & upload kernel dump (\windows\memory.dmp)?
Thanks.

done:

I can add that its the registered version she bought. If i install the free version, theres no problem.

Hi is there any update on this one? Right now the avast registered version is useless to my wife… alternatively can you maybe point me in which direction to get to a customer service so she can get her money back?
