Need help to investigate this file please

Hello,

I had an Alueron L on my MBR 0, I followed what someone said in the forum which is:

Download aswMBR.exe, run it , save the log and then download tdskiller.exe and run it.

Now here is my problem, I have downloaded pretty much all the tools on the net, none are working against this file.

I have a file in the system32 called sptd.sys and the aswMBR.exe keeps telling me that the file is locked, this is true, I tried to open it without luck.
Then the aswMBR.exe program found 2 other rootkits called

ntoskrnl.exe CLASSPNP.SYS disk.sys ACPI.sys >>UNKNOWN [0xfffffadf38c212c0]<<

and

\Driver\atapi[0xfffffadf3843b620] → IRP_MJ_CREATE → 0xfffffadf38c212c0

Now, when I use the tdskiller application, it removes the 2 above without a problem but unfortunatly cannot repair nor open the sptd.sys, a few minutes later, the 2 lines above reappear again…I just cannot get rid of it.

Here is the aswMBR Log:

Can I upload the sptd.sys to the forum or is it a risk for the others and myself??? I have no idea what is inside this file.

My operating system is Windows XP pro 64 bit fully updated.

Thank you,

Ben

Follow this guide from our expert malware remover Essexboy
http://forum.avast.com/index.php?topic=53253.0
( post the logs here and not in the guide )

To avoid using multiple post with copy and paste you have to attach the log`s
Lower left corner: Additional Options > Attach ( Malwarebytes log / OTL log ) save OTL log as ANSI

Essexboy will look at the logs when he arrive here later today…

Thanks, I just deleted the file, I dont think it is a problem now.

Thanks again,

Ben

At the very least I would suggest that you run aswMBR again and post the log.
