As MBAM was scanning, the computer rebooted itself.
It goes into an error screen that says something along the lines of
"A problem has occured and windows is unable to start."
It then reboots itself again, and enters the error screen again.
Each one has a different error after the 'windows is unable to start' line.

IRQL_NOT_LESSOREQUAL (Npfs.sys)
BAD_POOL_HEADER (MountMgr.sys)
KERNEL_TRAP_MODE (si3112r.sys)
BOGUS_DRIVER (hidusb.sys, usbhub.sys)

I rebooted the computer manually before I jotted down more.
I also noted at the bottom of the error screen, each had a TECHNICAL INFORMATION Header.
Each of them had a filename (the names in parentheses, BOGUS_DRIVER came up twice with different filenames), followed by "Address base ____ at _____, Datestamp Header_____"
With the lines filled in by letters and numbers I don't understand.

Are you still able to log onto your system and see the desktop?
I did not expect this to happen.
I admit it, this is the first time I'm seeing it.

Yes, everything is pretty much functional aside from the problems I've mentioned.

Fine, thanks for the info. I thought I destroyed the access to your computer.

Please download F-Secure Blacklight to your system and save it in your C:\ drive.

• Click Start and then Run.
• Type the following :
  
  (Toggle Plain Text)

  C:\fsbl.exe /expert

  C:\fsbl.exe /expert
  
  and press enter
  
• Select I accept the agreement
• Click Next then Scan & wait for the scan to finish
• Click on Next> then Exit
• A log will be produced in the C:\ drive
  It will be named fsbl-xxxxxxxxxxxxxx.log where xxxxxxxxxxxxxx is the date and time of the scan
• Use Notepad to open that log and
  Post the contents of that log as a reply to this topic.

It seems whatever's on my computer is denying access to the F-Secure link you provided. Is there maybe a way of uploading it onto DaniWeb in an attachment? Or another link?

I found a download link for it here: http://www.pcworld.com/downloads/fil.../download.html

It may be another version, but anyway, I tried running it and I get an error window that says "fsbl.exe is not a valid Win32 application".

Hi, that is the correct download.
Please try renaming fsbl.
Now I'm really getting suspicious that there might actually be a rootkit in your system.
My plan was to see what was causing Antivirus XP to keep coming back.

Please try renaming fsbl to something totally different.

No dice :/. "tryagain.exe is not a valid win32 application"

Ok, I trust you know how to boot into Safe Mode?
Please boot into Safe Mode and then run fsbl.exe

If that doesn't work, then delete that file and then download it from here.
If it still doesn't work, then please do the following.

Please download GMER and save it to your desktop:

• Unzip (extract) it to your desktop.
• Disconnect from Internet and close all running programs.
• There is a small chance this application may crash your computer so save any work you have open.
• Double-click gmer.exe to run it.
  Let the gmer.sys driver to load if asked.
• If it gives you a warning at program start about rootkit activity and asks if you want to run a scan... click NO.
• Click the Rootkit tab.
• Make sure all the boxes on the right of the screen are checked, EXCEPT for "Show All".
• Then click the Scan button. Wait for the scan to finish.
• Once done, click the Copy button.
  This will copy the results to the clipboard.
• Open Notepad and press CTRL + V to paste the log, and save it to your desktop.
• Attach this log to your next reply.

NOTE: If you're having problems with running gmer.exe, try it in Safe Mode. This tool works in Safe Mode whereas many other rootkit revealers do not.

Okay, before I read your last post, I tried MBAM again (Once again, closing lphclnbj0e57j.exe prior) and this time, it did not reboot.

My desktop is back to normal and I think my browser is running okay again, but you better take a look.

Hi, excellent !
I've been trying to get this result for a long time. It would have worked before itself, but I have no idea why it did not work.
I think it was because lphclnbj0e57j.exe was running in the background.

I think you may be able to run Blacklight now.
Please post the log in your reply.
