Windows 7: iaStor BSOD

iaStor BSOD

This seems like a fairly common occurrence. I ran malwarebytes and found a rootkit.agent, two hijacker.apps, a trojan.downloader, and a broken.command. All of these have been repaired. Also cleaned up the registry and applications with ccleaner. I ran into a problem with the mbr which I fixed with a recovery disk. Now I still cant boot in normal mode without super-fast BSOD which forces reboot, so I cant tell if its the same BSOD or not. I have run the dump collecting program but the perfmon has not generated any reports, so I have provided the folder anyway.

Where would I find and how would I replace the iaStor.sys files if I need to do it?

Thanks for any input.

iaStor.sys is the driver for Intel Matrix Storage Manager
Update it in safe mode with networking Intel® Driver Update Utility

Word to the wise, the iaStor driver name is now "Intel Rapid Storage Technology," it used to be called something else and unless you are aware that the name has changed, you'll be looking for something with matrix in the title.

Another word to the wise. there's a RootKit that someone generously released as an Xmas present doing the rounds. This affects iastor.sys
Download TDSSKiller and run it in Safe Mode to rule out the RootKit.

Thanks for everyones' suggestions...
Here is the winning formula for anyone that needs it in the future, or right now for that matter.....DON'T GET UPSOLD BY TECH SUPPORT ON THIS!!!!!

Ran Malwarebytes in safe mode. RootKit detected, so I deleted it. Afterwards, I was still getting the BSOD upon windows normal start.

Let it be known, that HP support did not help in the least as they told me immediately the HDD would need to be replaced. So I immediately ended that tech support chat, popped in a windows 7 recovery CD, pulled up the cmd and executed a well-deserved fixmbr...i.e. bootsect /nt60 etc.... DONE! so those guys should scrap the HDD upsell.

Next, ran the TDSSKiller in safe mode with networking, but I had already wiped it out with Malwarebytes(I assume, because the TDSSKiller did not find any offensive ware)

Next, went into the C:/windows/system32/drivers and deleted the iaStor.sys driver file.

Next, system wouldn't boot for a while, but eventually after repeated attempts it did boot in normal mode. I downloaded the Matrix Storage Manger, P.S.(there are two, so download and install the file with the name ending in *ENU.exe, thats what worked for me)

Next, ran CCleaner registry cleaner multiple times until all errors were resolved(except one annoying recurrence anyway)

Next, ran Malwarebytes again to confirm no offenses.

Finally, system nominal, created restore point

Matrix Storage Manager is the out-dated version and it still may cause BSOD if you ever try to burn a data DVD or CD. Look for the "Intel Rapid Storage" version.

Which Download?

Which product should I download? As there are many selections for Windows 7 64-bit Intel Rapid Storage. It was not my computer to begin with. The end user has the Home Premium and will never use a RAID array, of this I am certain. Also, will it require the *ENU.exe file or the other option?

Selections are as follows:
Intel® RST Driver Files (for version 10.1) - F6 Install (64-bit)
Intel® Rapid Storage Technology
RAID: Intel® Rapid Storage Technology Driver for Intel Desktop Boards

Oh, and its a pavillion notebook, so I assume the "for desktop boards" should not be used, so which of the other options, AND, which subselection?

iaStor.sys BSOD
I've been getting repeated BSODs related to iaStor recently. So far I have downloaded Malwarebytes, SuperAntiSpyWare, and TDSSKiller and none of them have turned up any malware, so a rootkit can presumably be ruled out. I did the scans both in and out of safe mode. I've also reinstalled the driver...
