Don' know what caused BSOD

What could have caused my bsod? Only has happened one time (i hope) and concerned because this is a new laptop. Could you help me find out what caused this? Thanks.

Windows 7 Home Premium 64 bit
OEM version with Lenovo Y570 laptop
bought the laptop just last April 2012

P.S.
All I was doing at that time was surfing the web and transferring files to my usb flash drive.

1. You problems may be related to iaStor.sys Intel Matrix Storage Manager driver - ia32.
Reinstall the newest version available...



2. Avast can be a contributing cause of BSOD'S .
Please remove and replace with Microsoft Security Essentials AT LEAST TO TEST

Hi, its happened again for the second time. Now I remember the 2 things in common that was going on during the 1st and 2nd bsod. I was transferring some large files to my usb flash drive and I was surfing the net. I checked my iastor.sys driver and i think its the latest driver. Here is the new bsod dump report.

Crashes are network related and hard disk related. The common cause of these is antivirus software. I suspect your avast! installation may be corrupted. Uninstall avast! with the avast! uninstall utility and download a fresh copy and re-install it. If that does not resolve it, use the avast! uninstall utility again and replace avast! with Microsoft Security Essentials - Free Antivirus for Windows.
