About two hours ago my AVG Anti-Virus Free 2011 detected around 3 Trojan Horses that were infecting my computer. I cleaned those viruses out, yet the Trojan Horse Agent_r.XJ was persistent beyond belief. I freaked out, and I began to run Malwarebytes, Ad-Aware, and my AVG scanner. I don't recall what happened, but my three programs detected some infections and removed them (other than the Agent_r.XJ). After searching on google, I followed an instruction to run my computer on safe-mode and run the Kaspersky TDSSKiller.exe . The TDSSKiller found an infection and was able to remove it. Now, when I run all my scanners (Malwarebytes, Ad-Aware, AVG), none of those programs are able to detect a single infection. Am I completely safe? What can I do to make sure the virus is completely gone? What precautions can I take next time to avoid this from happening again?

p.s. I am not very computer savvy, so I apologize if I do not completely understand what you have posted.

Thank you for your help!

You should have nailed it with TDSS as it was that rootkit.

We can try an online scan if AVG 2011 allows it, that program hates a lot of things.

ESET Online Scanner:

Note: You can use either Internet Explorer or Mozilla FireFox for this scan. You will however need to disable your current installed Anti-Virus, how to do so can be read here.

Vista/Windows 7 users: You will need to to right-click on the either the IE or FF icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run as Administrator from the context menu.

  • Please go here to run the scan.

    Note: If using Mozilla Firefox you will need to download esetsmartinstaller_enu.exe when prompted then double click on it to install.
    All of the below instructions are compatible with either Internet Explorer or Mozilla FireFox.

  • Select the option YES, I accept the Terms of Use then click on: Posted Image
  • When prompted allow the Add-On/Active X to install.
  • Make sure that the option Remove found threats is NOT checked, and the option Scan archives is checked.
  • Now click on Advanced Settings and select the following:
    • Scan for potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth Technology
  • Now click on: Posted Image
  • The virus signature database... will begin to download. Be patient this make take some time depending on the speed of your Internet Connection.
  • When completed the Online Scan will begin automatically.
  • Do not touch either the Mouse or keyboard during the scan otherwise it may stall.
  • When completed select Uninstall application on close if you so wish, make sure you copy the logfile first!
  • Now click on: Posted Image
  • Use notepad to open the logfile located at C:\Program Files\ESET\EsetOnlineScanner\log.txt.
  • Copy and paste that log as a reply to this topic.
Note: Do not forget to re-enable your Anti-Virus application after running the above scan!

NOTE: In some instances if no malware is found there will be no log produced.

Ok ,this looks good it found something that it cannot clean. Good because now we know where it is. Now tho we'll need specilized tools and an assistant to clean this.

Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here. Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
Name it Java/TrojanDownloader.OpenStream.NAY trojan (unable to clean)
If Gmer won't run,skip it and move on.
Let me know if that went well.

Hey boopme, I just finished all the steps and have made my post on the "Virus, Trojan, Spyware, and Malware Removal Logs" as you said. I think I did everything correctly, sorry if I made any mistakes. Thanks for your patience and help so far, I appreciate it greatly.

Malware topic here: http://www.bleepingcomputer.com/forums/topic386849.html

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 MR Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
The power of accurate observation is commonly called cynicism by those who haven't got it.
