I have been infected. I'm guessing it is a Trojan. NOD32 caught Win32/TrojanDonwloader.Bredolab.AA after a full scan, but the problems had already begun. It replaced my background image and continues to replace any background image I choose with a WARNING graphic and includes pop-ups every few minutes for some B.S. software TotalSecurity2009 trying to get me to "Activate" its software. NOD32 asked and I selected to Delete iKowin32.exe from My Documents and one other location. It appears to be in memory or registry or other to keep popping up and it also installed a system tray icon and desktop shortcut (which I deleted).

Prior to today, NOD32 caught a BHO.NOQ trojan twice in the past couple of days. I imagine this could be related to the current issues.

I have HijackThis but need help figuring out what to remove to be rid of this Trojan.

Here's a screen shot:

Please provide help if you can.

I included HijackThis loga in the HJ forum here: http://www.bleepingcomputer.com/forums/topic255997.html

Hello and welcome to Bleeping Computer

Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

To subscribe, go to your topic, and at the top right hand corner by your first post, click the Options button and then click Track this topic. The bullet the immediate notification bubble. Then press submit.


Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full 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 MBAM report (even if it does not find anything) 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 immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

I downloaded and ran Malwarebytes. Did not see how to rename it when downloading. I think it's a Firefox thing. Anyway, it donwloaded and ran just fine, I think. Here is the log:

Also, I noticed some highleted RED reg keys in Spybot S&D Start Menu list. I unchecked them and found two instances of mspn32.exe in a search, then deleted it after searching for it on bleepingcomputer.com and seeing it is linked to a trojan.

So, my PC now appears to be alright. The TotalSecurity 2009 graphics are gone and nothing seems to be interfering with running Malwarebytes, Spybot or NOD32. Do you recommend taking any further steps?

Thank you, so much. You are greatly appreciated!

Lets run another scan:

Please run ATF and SAS:
Credits to Boopme

Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

Note 2: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware, Free Home Edition

Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.

OK. Thanks. I followed the instructions, downloaded and ran the ATF & SUPER apps in SAFE mode. Here's the log:

SUPERAntiSpyware Scan Log
http://www.superantispyware.com

Generated 09/12/2009 at 11:17 AM

Application Version : 4.28.1010

Core Rules Database Version : 4096
Trace Rules Database Version: 2036

Scan type : Complete Scan
Total Scan Time : 00:34:37

Memory items scanned : 235
Memory threats detected : 0
Registry items scanned : 6199
Registry threats detected : 0
File items scanned : 48239
File threats detected : 0

I do have an issue, though. After completing these stapes in safe mode, I restarted Windows, however, it appears to do so in a sort of continued safe mode...classic style windows graphics, no networking and runtime errors for RoxWatch (Blackberry app) and "can't communicate with NOD32 kernal" errors. No Windows services for intall or uninstall available.

If I select 'Restart Windows Normally' from the F8 menu, it still loads this unusual safe mode version, however, if I select Restart Windows in Last Known Working State, then it loads with the full version.

Am I missing something? Why would it do this? And, is it alright if I continue after selecting Restart Windows in Last Known Working State?

Thanks again for your guidance.

Ok, it sounds like you need to run sfc /scannow. Do you have a Windows disk that came with your computer or that you could borrow from someone?
