Hi,

I have a computer I am trying to clean that keeps popping up messages saying a threat has been detected and asking if you want to scan for viruses (Alert! You have a security problem! Do you want to scan your computer for viruses?). It will then pop up a webpage after the message box opens. I have run SuperAntispyware (in safe mode) and it does not detect anything. I have run Malwarebytes Anti-Malware (in safe mode) and it sees 2 items:

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.

When I told it to remove the infected items it did, as noted above, but they still keep popping up again. I am guessing something else is creating these files but I am not sure where to go from here. Any help would be appreciated.

Thank you...

What version of Windows are you using?
What antivirus product?

This PC is running Windows XP with SP3 and the AV is McAfee Total Protection for SB version 4.7 (AV and AntiSpy) through a SonicWall firewall.

Let's try SDFix

Please print out and follow these instructions: "How to use SDFix". <- This program is for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to renable you anti-virus and and other security programs before connecting to the Internet.
-- If the computer has been infected with the VirusAlert! malware warning from the clock and the Start Menu icons or drives are not visible, open the SDFix folder, right-click on either the XP_VirusAlert_Repair.inf or W2K VirusAlert_Repair.inf (depending on your version of Windows) and select Install from the Context menu. Then reboot to apply the changes.

After rebooting, I uninstalled and reinstalled my McAfee Total Protection and it seems to have eliminated whtever was left from this trojan. I ran MBAM again and it no longer finds any detections (log pasted below). Is there anything else I should run to verify I am now 'clean'?

Please perform a scan with Eset Onlinescan (NOD32).
(Requires Internet Explorer to work. If given the option, choose "Quarantine" instead of delete.)
Vista Users be sure to run Internet Explorer as Administrator. To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select "Run as Administrator" from the context menu.)
  • You will see the Terms of Use. Tick the check-box in front of YES, I accept the Terms of Use
  • Now click Start.
  • You may receive an alert on the address bar that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then Click Insall ActiveX component.
  • A new window will appear asking "Do you want to install this software?" (OnlineScanner.cab)".
  • Answer Yes to install and download the ActiveX controls that allows the scan to run.
  • Click Start. (the Onlinescanner will now prepare itself for running on your pc)
  • To do a full-scan, check: "Remove found threats" and "Scan potentially unwanted applications"
  • Press Scan to start the online scan. (this could take some time to complete)[/color]
  • When the scan has finished, it will show a screen with two tabs "overview" and "details" and the option to get information or buy software. Just close the window.
  • Now click Start > Run... > type: C:\Program Files\EsetOnlineScanner\log.txt
  • The scan results will open in Notepad.
  • Copy and paste the log results in your next reply.
Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

If there are no more problems or signs of infection, 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.
  • 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.
