Hi, earlier this morning I was online streaming music video's in the background while I was working on some homework. When one of the songs ended, I wanted to hear some lyrics repeated so I went to move the clip position icon from the end back to the middle. When I moved this, my computer froze up for a couple of seconds and then about 5 or 6 Firefox windows popped up saying I was infected and that I had a problem with security on my computer. I figured this was fake as it was telling me that I had the problem yet still it had changed my settings. When all the windows popped up, I quickly closed every application that I had open and I was going to run a McAfee Virus Scan. Once I had closed Firefox, it started to update to a newer version. I feared that this was some sort of malicious software being installed so I cold shut down my computer by hold the power button for 5 seconds. I let the computer sit for a couple of seconds and then restarted it. The computer ran slow and there were pop-ups everywhere about how the comp. was infected. (After some research I found out that a program called fraud.XPantivirus was the cause of this particular problem) With the hold of my girlfriend we downloaded "Spybot S&D" to get rid of all the problems. This got rid of most but left about 4 or 5 that would come back even after restarting the computer when it said it had been fixed. I found a lot of posts that recommended "Malwarebytes anti-Malware" so I installed this and and ran the program. this took care of the fraud.XPantivirus program and the others found by the spybot S&D but found several more problems that it was able to fix and two that it couldn't fix. After having Malwarebytes say it was fixed, it would re-appear when the computer was rebooted. I tried to get rid of it several times as well as running the virus scan a couple of times. Nothing got rid of it. I then searched online and found an almost exact problem description as mine between two bleepingcomputer users Amandinxia and Thunder on Jan. 18th 2009. so I decided to post the problem here. From running the malwarebytes program, these are the two items that kept popping up every time I ran it (the exact error as the other user).

Registry Data Items Infected:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Userinit (Trojan.Agent) -> Data: c:\windows\system32\userinit.exe -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Userinit (Trojan.Agent) -> Data: system32\userinit.exe -> Quarantined and deleted successfully.

How do I get rid of these items? I thought about trying the exact solution posted in response to Amandinxia but as this user was posting file logs which were specific to her problem, I wanted to know If I should do the same. Also, this user posted a dds.txt log and I don't know how to do that. I would like to get rid of these items as it would be nice to have a clean computer again. Please help...and thank you in advance.

Hello and welcome. this will be an either or fix.. So let's do MBAM (either) and get a log. So I can also see your Service Pack.
run MBAM:
Please download Malwarebytes Anti-Malware (v1.32) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

thank you for the help. I have the Malwarebytes' Anti-Malware version 1.34 ( I downloaded it yesterday) I guess this one is newer than the 1.32 you asked me to run. Let me know if I need to find that version. Here is the log file that it generated. It says that the two problems with the registry are fixed, but when I restart the computer and rerun Malwarebytes anit-malware, the same problems are found again...(the problem is not fixed).

Ok yes the newest is OK. I actually wanted to see this. Actually MBAM can't repair these system files and you need to remove and reinstall SP3 to fix it.

question, do I run mbam in between the uninstall and reinstall of SP 3, or do I run it at the end of the re-install, or will the uninstall-reinstall fix the problem itself?

Option C... or will the uninstall-reinstall fix the problem itself?
MBam will not fix the system file,

It looks like the problem is fixed. I uninstalled and reinstalled Windows SP#3, ran mbam again and no problems/errors came up. Thanks for the help. I pasted the mbam log file below so you can look at it if you wish. Again, many thanks!

There you go,good work!! It's fixed and clean.
Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
