Hi..

My computer just recently got infected by a virus.. I have no idea what to do. I've watched a few tutorial videos but I can't find out the name of the virus. any help?

here are the details:

from the beginning my security center service was shut off and when I tried to turn it back on a prompt pops up saying "the security center service can't be started"
in addition my security essentials (firewall,auto updates,malware protection,other sec. settings) are off and I can't turn them back on..

when I did used an antivirus program to scan this is what came up:

Infection: name- Trojan horse FakeAlert.MN
Path to file: C:\Windows\System32\UACodrrdorxit.dll

please help..

thanks :]

-- Vista users can refer to these instructions to open a command prompt.

Alternatively you can do this:

Please download peek.bat and save it to your Desktop. Double-click on peek.bat to run it. A black Command Prompt window will appear indicating the program is running. Once it is finished, copy and paste the entire contents of the Log.txt file it creates in your next reply.

If you encounter a problem downloading or getting peek.bat to run, go to Posted Image > Run..., and in the open box, type: Notepad
  • Click OK.
  • Copy and paste everything in the code box below into the Untitled - Notepad.
@ECHO OFF
DIR /a/s C:\WINDOWS\scecli.dll C:\WINDOWS\netlogon.dll C:\WINDOWS\eventlog.dll C:\Windows\cngaudit.dll >Log.txt
START Log.txt
DEL %0
  • Go to File > Save As, click the drop-down box to change the Save As Type to *All Files and save it as "peek.bat" on your desktop.
  • Double-click peek.bat to run the script.
  • A window will open and close quickly, this is normal.
  • A file called log.txt should be created on your Desktop.
  • Open that file and copy/paste the contents in your next reply.
-- Vista users, users can refer to these instructions to Run a Batch File as an Administrator.

Now that you were successful in creating those two logs you need to post them in our HJT forum Their they will help you with the removal through some custom scripts and programs that we cannot run here in this forum

First, try to run a DDS / HJT log as outlined in our preparation guide:
http://www.bleepingcomputer.com/forums/t/34773/preparation-guide-for-use-before-using-malware-removal-tools-and-requesting-help/

If it won't run, don't worry, just give a brief description and tell them that these logs were all you could get to run successfully

Post them here:
http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/

The HJT team is extremely busy, so be patient and good luck
