Hi, I was infected with antivirus live fake virus scan. I was able to successfully remove it using malwarebytes anti-malware, but I still am running at 100% CPU usage and occasionally when my AVG virus scan runs it will find these two items: Trojan Horse Vundo.JK and Trojan Horse Generic 16.KTZ

Also, when I have attempted to restart using Safe Mode (any form; w/ networking, w/o ect.) the computer will go into blue screen after loading all the files and before moving to another screen.


Here is the Malwarebytes log that found and removed the antivirus live:

All subsequent scans have came clean.

I have also ran ATF-Cleaner and SUPERAntiSpyware (properly updated), and using the correct method as posted in a previous thread on how to remove Trojan Horse Generic 16.

I have just updated malwarebytes and I am running it again to be certain that is clear, I will post the log when that is finished.

I have also ran trend micro house call which came up with nothing. I have tried Kaspersky but they are updating as I am sure you know.

Thanks in advance for the help I anticipate your response.

ps. this is a different computer then I have last had problems with just in case you guys do a past post check to see if this is related to past problems.

Hello, there are two more things I would like to try here.

SUPERAntiSypware has a built in "Repairs" feature to fix policy restrictions and certain Windows settings which are sometimes targeted by malware infection. To use this feature, launch SUPERAntiSypware.
  • Click the Repairs tab.
  • Click on (highlight) "Repair broken SafeBoot key" and then click the Repair button.
  • You may be asked to reboot your computer for the changes to take effect.

We Need to check for Rootkits with RootRepeal
  • Download RootRepeal from the following location and save it to your desktop.
  • Extract RootRepeal.exe from the archive (If you did not use the "Direct Download" mirror).
  • Open Posted Image on your desktop.
  • Click the Posted Image tab.
  • Click the Posted Image button.
  • Check all seven boxes: Posted Image
  • Push Ok
  • Check the box for your main system drive (Usually C:), and press Ok.
  • Allow RootRepeal to run a scan of your system. This may take some time.
  • Once the scan completes, push the Posted Image button. Save the log to your desktop, using a distinctive name, such as RootRepeal.txt. Include this report in your next reply, please.

Ok there are 2 rootkits there. Did Safe Mode work?

Failure to follow the proper removal process can and will cause serious damage to a machine. Recovery of the machine may be difficult, if not impossible.

You will need to run HJT/DDS.
Please follow this guide. go and do steps 6 thru 8 ,, Preparation Guide For Use Before Using Hijackthis. Then go here HijackThis Logs and Virus/Trojan/Spyware/Malware Removal ,click New Topic,give it a relevant Title and post that complete log.

Let me know if it went OK.

Thanks for the help, I did not get to check safe mode yet. I am going to do that later today.

I won't be able to remove rootkits for a few days, what are your thoughts on using the computer in the interim? should I keep it off, there is another usable computer. Is it bad to run while the rootkits are still on the computer?

Thanks.

Hi you should post in HJT soona s it will take a few days.. Then stay disconnected as much as possible.

Rootkits, backdoor Trojans, Botnets, and IRC Bots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. Rootkits are used by Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:

What danger is presented by rootkits?
Rootkits and how to combat them
r00tkit Analysis: What Is A Rootkit

If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised and change each password using a clean computer, not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/286915/computer-1-tons-of-rootkits-found/ 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 HJT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in 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 HJT 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 HJT Team members are EXTREMELY 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 HJT 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.

Please be patient. It may take several days, up to two weeks perhaps less, to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
