Random BSOD multiple errors ntoskrnl.exe+75bc0 bug check 0x00000101

I am working on a laptop that has been getting random BSOD usually while nothing special is running. I have run memory checks, several antivirus scans to remove a lot of malware and trojans. Finally at my wits end with this. I would very much appreciate it if someone could point me in the right direction as to what is causing it.

Acer Aspire 7750-6669
Intel Core I3-2350M
6GB memory

Thanks in advance

    Then Uninstall the driver from device manager.

    Right click on "my computer" icon and click "manage" on the context menu.
    It will open the "computer management" window.
    Select "Device Manager" in the left pane, It will list all the existing devices up.
    Expand "IDE ATA/ATAPI controllers" by clicking on the triangle in front of it.
    Select one Intel device item under it, right click, uninstall.
    Continue the process for all Intel items under "IDE ATA/ATAPI controllers"
    Now restart the computer. At restart, windows will auto configure the appropriate native system driver.

Remove AVAST:

Missing SAS (SuperAntiSpyware) files:
SASDIFSV    ROOT\LEGACY_SASDIFSV\0000    This device is not present, is not working properly, or does not have all its drivers installed.
SASKUTIL    ROOT\LEGACY_SASKUTIL\0000    This device is not present, is not working properly, or does not have all its drivers installed.
  • Please reinstall.
Cleanup your startup:

I have removed IRST as instructed as well as Avast Antivirus & Morton Online Backup. These were done upon receiving your instructions.

Done prior to receiving instructions:

Opened MSConfig and removed unwanted programs from startup.
However this machine was severely infected with malware. The MBR was infected with Alureon virus as indicated by Microsoft malicious software removal tool. I booted from the Windows Offline scanner disk and was able to remove it.

I have not received any BSOD since performing these actions. I will keep you posted as to the progress of the system should there be anymore issues.

Once again Thanks for your help.
