Hi guys,

Thank you so much for your assistance in advance. I've been having strange problems with my laptop since last night; the laptop would randomly lock up sometimes when accessing the harddrive (or clicking on the tool bar) and experience extreme slowdowns.

The accessing harddisk light seemed to be almost always on; examination of process explorer showed that services.exe was reading/writing to the disk almost constantly. Usually after about 15 minutes or so the system would lock up and make a loud sustained "beeeeeeeeeep" from the laptop's pc speaker, until I turn off the computer.

I also tried defragging which showed the drive almost entirely fragmented, and it was only able to get a 25% fragmentation down to 22%. On a friend's advice, I ran antimalware bytes (to no avail) and combofixer, which according the log, indicated that I had an MBR Rootkit.

RootRepeal fails to run, crashing on start up with the following code:
ROOTREPEAL CRASH REPORT
-------------------------
Windows Version: Windows XP SP3
Exception Code: 0xc0000094
Exception Address: 0x004eca19

Per your tutorial, I am posting the DDS diagnostic log here.
