I've recently lent out my laptop to a roomate, and when I got it back it had seemingly been hijacked by what I think is a combination of viruses. He said that he was downloading some .pdf files for his research when all of a sudden cmd was initiated. The computer runs "Security Tool" and "Antivirus XP" whenever I try to open up anything. My task manager had also been hijacked, but I got it back by deleting a registry. These bogus scanners try to scan my computer and tell me a bunch of legit files are infected. My internet (both wireless and non) has stopped working. Furthermore, the icons nudetube.com, youporn.com, pornotube.com, and Security Tool have appeared on the desktop.

I'm kind of desperate, and don't know what to do. I need you guys' help. Since I can't access the internet, I'm thinking of using my phone as a flash drive to download any programs you guys want me to use and transfer any logs the same way to this computer. Thank you in advance.

So, I was on step 6 on the guide and after I clicked on "Finish" I got an error message that said,

Malwarebytes' Anti-Malware

"An error has occured. Please report this error code to our support team.

MBAM_ERROR_UPDATING (12007, 0 WinHttpSendRequest) "

I was still able to run the scanner and continue with the guide.

Once my computer restarted, a window of another bogus scanner named Antimalware Doctor appeared.

Reboot and run the scan again.

I ran the scan a few times and also did it in safe mode, and it always found a few infected files. Antimalware Doctor still appears at start up along with a few computer error messages.

The first error message that appears says,

Generic Host Process for Win32 Services

Generic Host Process for Win32 Services has encountered a problem and needs to close. We are sorry for the inconvenience.

If you were in the middle of something, the information you were working on might be lost.

Please tell Microsoft about this problem.
We have created an error report that you can send to help us improve Generic Host Process for Win32 Services. We will treat this report as confidential and anonymous.

To see what data this report contains, click here.

[Debug] [Send Error Report] [Don't Send]



The second error message that appears says,

Fatal error (10)

The key file does not exist.

[ OK ]

I'm not sure, but I want to say those errors pertain to Security Tool and Antivirus XP trying to reinstall/restart up again.

Also, there were two different kinds of Antimalware Doctor windows, Malware bytes got rid of one, but not the one that is left.

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.

    Posted Image
  • 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.
  • Uncheck all the boxes on the right hand side except Sections, 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 be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Would you like me to post the new logs here or make a new thread?

Also, thanks for all your help and work Budapest; I know you guys aren't paid to do this and your work is voluntary--you are much appreciated.

Edit: Oh, I just realized it's a new forum where I'm supposed to post, so my question is answered. Thanks again Budapest.

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic
