Hi. New victim here.

I was downloading a file from Megaupload today. I left the room briefly and returned to find "Antivirus Soft" in full swing. Attempts to disable it via Task Manager were blocked by the "Security Warning" telling me the task manager file was infected. As I sat in a mild panic a large amount of Windows Security warnings popped up, accompanied by the bogus "Security Warnings".

I attempted to follow the instructions elsewhere on this forum for getting rid of Antivirus Soft, using rkill and MBAM and Safe Mode, etc. However, I have been unable to update MBAM (error code 732, whatever that is), and it found very little in the way of infection (three suspect registry keys were found):

Registry Values Infected:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer\forceclassiccontrolpanel (Hijack.ControlPanelStyle) -> Quarantined and deleted successfully.

Registry Data Items Infected:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\FirewallDisableNotify (Disabled.SecurityCenter) -> Bad: (1) Good: (0) -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\UpdatesDisableNotify (Disabled.SecurityCenter) -> Bad: (1) Good: (0) -> Quarantined and deleted successfully.

A subsquent MBAM scan found nothing.

I decided to post here, so I began by downloading and running DDS and gmer. However, I could not run gmer. I got a dialog box stating that "gmer has encountered a problem and needs to close". So I can only post the DDS logs.
I use Windows XP Home. The "Antivirus Soft" malware loads up with Windows Startup, with a small green icon in the taskbar. I am using rkill to stop the process.

This is my first significant infection on this 7-month-old PC. Any help on how to proceed is greatly appreciated.

Hi again.

I know I'm supposed to wait for a reply before I post again, but I did some additional research about attacking this Antivirus Soft monster. The initial MBAM scan didn't find it, but I read elsewhere that Antivirus Soft will somehow interfere with antivirus/antispyware installation. So I went back into Safe Mode and downloaded SuperAntiSpyware. But before I saved it I renamed it as "iexplore.exe", and then installed it. It found the following:

Rogue.AntivirusSoft
[uxnfyjhr] C:\DOCUMENTS AND SETTINGS\OWNER\LOCAL SETTINGS\APPLICATION DATA\DHAODR\GPDWSFTAV.EXE
C:\DOCUMENTS AND SETTINGS\OWNER\LOCAL SETTINGS\APPLICATION DATA\DHAODR\GPDWSFTAV.EXE
[uxnfyjhr] C:\DOCUMENTS AND SETTINGS\OWNER\LOCAL SETTINGS\APPLICATION DATA\DHAODR\GPDWSFTAV.EXE
HKU\S-1-5-21-842925246-583907252-682003330-1003\Software\avsoft

I did the same thing with MBAM (uninstalled, then downloaded the installer under a false name: winlogon.exe). Ran a scan in Safe Mode, and it found:

Registry Keys Infected:
HKEY_LOCAL_MACHINE\SOFTWARE\avsoft (Trojan.Fraudpack) -> Quarantined and deleted successfully.

I have restarted three times, and the telltale green icon doesn't show up. Also, rkill doesn't find it anymore.

For the time being, I'll assume that the infection is gone. Your guide (Remove Antivirus Soft (Uninstall Guide) was very helpful; however, might I suggest adding something about renaming the AV installers to increase the chances of detecting files and keys affected by Antivirus Soft.

Are there any additional scans I should do to ensure that the infection has been dealt with?

cheers

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Upon completing the steps below another staff member will review and take the steps necessary with you to get your machine back in working order clean and free of malware.

If you have already posted a DDS log, please do so again, as your situation may have changed.
Use the 'Add Reply' and add the new log to this thread.


Thanks and again sorry for the delay.

We need to see some information about what is happening in your machine. Please perform the following scan:
  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explaination about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE



Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.


  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.
regards,
schrauber
