Hello,

Last night while using my Toshiba Portege R705 laptop, I began to get various warnings implying a hard drive failure. I did not suspect anything until "Windows 7 Recovery" required me to go to a website which was not part of the microsoft.com domain to purchase the "advanced" module. I then researched this issue and discovered that it was a virus/malware. I discovered some advice on the issue, including bleepingcomputer. After trying to vain to shut down the offending processes, I discovered that I would have to use Rkill to stop the program before I could start the cleaning process. After killing the program, I ran Malwarebytes anti-malware program, which eliminated some problems and generated the attached logs. I ran unhide.exe so that I could again view my files. I then downloaded an ran Combofix (unknowing that I wasn't supposed to run this without first being asked). I was forced to uninstall Webroot to get Combofix to complete. Once completed, it generated the log attached. Finally, I downloaded and installed Avira Free antivirus so that I could reconnect to the internet and create this post. I would like someone to help me determine:

1. Have I sufficiently cleaned my system, as best can be told from the attached logs?
2. What will I need to do to get my computer back to its preinfected state? My desktop seems back to normal but other settings and my start menu have not returned to normal.
3. What steps do I need to take to prevent this from happening again?

Thanks very much for being willing to provide this free service on the internet. This was a most unpleasant experience, but glad to know there are good Samaritans out there willing to help people get their computers back working again.

Attaching DDS log.

Laptop worked fine for a day or so, then the virus resurfaced this morning. Avira attempted to quarantine the virus, but it managed to start and hijacked it again, disabling Task Manager, preventing me from loading web pages, and giving the fake hard drive warnings. I did a forced shutdown, but then the computer would not boot, it just stayed on the windows 7 splash screen. Finally went to Target and bought Kaspersky anti-virus with a rescue disk, and am now doing a full system scan after booting into a Linux environment with the boot disk. Many trojans found, will post log after it completes (still estimates 3+ hours to complete scan).

Hello and welcome to the forums!

My secret agent name on the forums is SweetTech (you can call me ST for short), it's a pleasure to meet you. :)

I am very sorry for the delay in responding, but as you can see we are at the moment being flooded with logs which, when paired with the never-ending shortage of helpers, resulted in the delayed responding to your thread.

I would be glad to take a look at your log and help you with solving any malware problems.

If you have since resolved the issues you were originally experiencing, or have received help elsewhere, please inform me so that this topic can be closed.

If you have not, please adhere to the guidelines below and then follow instructions as outlined further below:

  • Logs from malware removal programs (OTL is one of them) can take some time to analyze. I need you to be patient while I analyze any logs you post. Please remember, I am a volunteer, and I do have a life outside of these forums.
  • Please make sure to carefully read any instruction that I give you. Attention to detail is important! Since I cannot see or directly interact with your computer I am dependent on you to "be my eyes" and provide as much information as you can regarding the current state of your computer.
  • If you're not sure, or if something unexpected happens, do NOT continue! Stop and ask!
  • In Windows Vista and Windows 7, all tools need to be started by right clicking and selecting Run as Administrator!
  • If I instruct you to download a specific tool in which you already have, please delete the copy that you have and re-download the tool. The reason I ask you to do this is because these tools are updated fairly regularly.
  • Do not do things I do not ask for, such as running a spyware scan on your computer. The one thing that you should always do, is to make sure sure that your anti-virus definitions are up-to-date!
  • Please do not use the Attachment feature for any log file. Do a Copy/Paste of the entire contents of the log file and submit it inside your post.
  • I am going to stick with you until ALL malware is gone from your system. I would appreciate it if you would do the same. From this point, we're in this together ;)
    Because of this, you must reply within three days
    failure to reply will result in the topic being closed!
  • Lastly, I am no magician. I will try very hard to fix your issues, but no promises can be made. Also be aware that some infections are so severe that you might need to resort to reformatting and reinstalling your operating system.
    Don't worry, this only happens in severe cases, but it sadly does happen. Be prepared to back up your data. Have means of backing up your data available.
