Windefender 2009 infection


Recommended Posts

Hello.

My computer seems to be infected with the windefender virus. A dialog box suddenly appeared, saying windefender was downloaded, and asked me to press "finish" or "cancel". I pressed the "close"-button in the top right corner. The WinDefender Control Panel then opened up. Again, I pressed the close-button. Firefox then closed, and I got a message saying it could not start because it was infected with "W32/Blaster.worm". This message soon affected tons of other programs. I tried running Malwarebytes Anti-Malware, but the same message prevented me from running it. It also prevented me from running Hijack This, Task Manager(closes immediately) or system recovery. I am writing this on a different computer.

Any ideas...?

Also, there seems to be a new (fake, I think) anti-virus program installed called "Spyware Protection".

Hello Andrimner! Welcome to Malwarebytes' Anti-Malware Forums!

My name is Borislav and I will be glad to help you solve your problems with malware. Before we begin, please note the following:

  • The process of cleaning your system may take some time, so please be patient.
  • Follow my instructions step by step if there is a problem somewhere, stop and tell me.
  • Stay with the thread until I tell you that your system is clean. Missing symptoms does not mean that everything is okay.
  • Instructions that I give are for your system only!
  • If you don't know or can't understand something please ask.
  • Do not install or uninstall any software or hardware, while work on.
  • Keep me informed about any changes.

Step 1

Please download and run the following tool to help allow other programs to run. (courtesy of BleepingComputer.com)

There are 4 different versions. If one of them won't run then download and try to run the other one.

Vista and Win7 users need to right click and choose Run as Admin

You only need to get one of them to run, not all of them.

  1. rkill.exe
  2. rkill.com
  3. rkill.scr
  4. WiNlOgOn.exe
  5. uSeRiNiT.exe
  6. iExplore.exe

Please post the log in your next reply.

Note: The log can be found at the root of your installed hard drive entitled rkill.log

Step 2

  • Launch Malwarebytes' Anti-Malware
  • Go to "Update" tab and select "Check for Updates". If an update is found, it will download and install the latest version.
  • Go to "Scanner" tab and select "Perform Quick Scan", then click Scan.
  • The scan may take some time to finish,so please be patient.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Make sure that everything is checked, and click Remove Selected.
  • When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
  • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
  • Copy&Paste the entire report in your next reply.

Extra Note:

If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediatly.

In your next reply, please include these log(s):

Hello Borislav, and thank you very much for assisting me with this problem!

One of the programs you provided was indeed able to run, and this is the first log:

This log file is located at C:\rkill.log.

Please post this only if requested to by the person helping you.

Otherwise you can close this log when you wish.

Rkill was run on 16.12.2010 at 22:50:02.

Operating System: Windows 7 Home Premium

Processes terminated by Rkill or while it was running:

C:\Users\Vegar\AppData\Roaming\defender.exe

C:\Users\Vegar\Downloads\uSeRiNiT.exe

C:\windows\system32\DllHost.exe

Rkill completed on 16.12.2010 at 22:50:20.

(NOTE: I had to run this program 2 times, because the Malwarebytes-program needed to reboot to install an update. This is the log from the program I run the 2nd time - the log from the first time only listed defender.exe, not the last two)

This is the second log, from MAM:
