Hi,

I got infected with sdra64.exe and a couple of days ago (when I didn't know I had this on my computer) I knew I got infected with something. I ran Malwarebyes Anti-Malware and it found 20 infections and removed them all.

Today I kept getting a notification on Windows XP asking permission to startup sdra64.exe and I ran Malwarebytes Anti-Malware again. It found 60 infections and removed all but 4 of them. Wanted to restart the computer so I let it.

It was still infected with sdra64.exe so I started looking online for fixes and decided to try Anti-Malware one more time and it will not run. I tried to run it and it a bubble pops up on the taskbar stating Warning! "Running of application is impossible. The file C:\Program Files\Malwarebytes' Anti-Malware\mbam.exe is infected. Please activate your antivirus program"

I now also have Windows Antivirus Pro popping up and running a fake scan on my computer about viruses trying to make me purchase the program. I'm NOT going to do that.

I also tried to go to Start - Run - msconfig and got the same error saying it can't run and it is infected.

I'm at a loss and need MAJOR help. The computer is no longer functions.

I'm currently using a different computer for the boards. HELP!!!

Immunize a usb drive and that clean computer

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.

I need you to retrieve those last 2 MBAM logs if you can

No. Try not. Do... or do not. There is no try.

http://www.prevx.com/filenames/X9302470815...SDRA64.EXE.html

The filename is associated with the malware groups:

Rootkit
Worm
Cloaked Malware
Information Stealer


One or more of the identified infections is a rootkit/backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

Someone may still be able to clean this machine but we can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.
