My wife's laptop is infected with a Sirefef virus and is stuck in a reboot cycle every two minutes which seems to be the standard for this infection. The MSE running on the computer picks up the Sirefef virus but of course cannot remove it in time. Per my research of others with the same virus who have posted on this forum I've run the FRST64 program and attached the log files for your review. I'm anxiously awaiting your response.

Thanks for your help,
Dave

I was able to resolve my virus problem by running Kaspersky TDSSKiller which kept finding the services.exe as infected. While it never had time to fix the problem I tried the following just to get to a point where it wouldn't reboot after 2 minutes so I could run a full scan:

1) Boot into Windows Repair mode
2) Select Command Prompt
3) Go to c:\windows\system32 and make a copy of services.exe
4) Go to Repair mode's windows\system32 directory (in my case x:\windows\system32
5) Copy the services.exe from the Repair Mode directory to c:\windows\system32 (overwrites the infected services.exe)
6) Reboot and start in regular start mode
7) With the new services.exe I was able to complete a full scan using MSE and the reboot issue has gone away
8) Rebuilt the Security Services following manual instructions found here http://www.doitscared.com/1259/recover-from-the-sirefef-y-virus-infection

While this appears to have fixed things on the surface I know that this particular virus can spread itself wide so if you still want to review the FRST64 logs and have me run anything I am more than willing to try additional measures to make sure it's not just hiding under the surface waiting to appear again or delivering private information via backdoor holes that I can't see right now.

Thanks,
Dave

Greetings And Welcome To The Forums!!

My name is Gringo and I'll be glad to help you with your malware problems.

I have put together somethings for you to keep in mind while I am helping you to make things go easier and faster for both of us

  • Please do not run any tools unless instructed to do so.
    • We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability.
  • Please do not attach logs or use code boxes, just copy and paste the text.
    • Due to the high volume of logs we receive it helps to receive everything in the same format, and code boxes make the logs very difficult to read. Also, attachments require us to download and open the reports when it is easier to just read the reports in your post.
  • Please read every post completely before doing anything.
    • Pay special attention to the NOTE: lines, these entries identify an individual issue or important step in the cleanup process.
  • Please provide feedback about your experience as we go.
    • A short statement describing how the computer is working helps us understand where to go next, for example: I am still getting redirected, the computer is running normally, etc. Please do not describe the computer as "the same", this requires the extra step of looking back at your previous post.
NOTE: At the top of your post, click on the Watch Topic Button, select Immediate Notification, and click on Proceed. This will send you an e-mail as soon as I reply to your topic, allowing us to resolve the issue faster.

NOTE: Backup any files that cannot be replaced. Removing malware can be unpredictable and this step can save a lot of hartaches if things don't go as planed. You can put them on a CD/DVD, external drive or a pen drive, anywhere except on the computer.

NOTE: It is good practice to copy and paste the instructions into notepad and print them in case it is necessary for you to go offline during the cleanup process. To open notepad, navigate to Start Menu > All Programs > Accessories > Notepad. Please remember to copy the entire post so you do not miss any instructions.


I would like you to rerun FRST64 for me and send a new report

download Farbar Recovery Scan Tool x64 and save it to a flash drive.

Plug the flash-drive into the infected PC.

Enter System Recovery Options.

  • Use the arrow keys to select the Repair your computer menu item.

  • Select the operating system you want to repair, and then click Next.
  • Select your user account an click Next.

To enter System Recovery Options by using Windows installation disc:
  • Insert the installation disc.
  • Restart your computer.
  • If prompted, press any key to start Windows from the installation disc. If your computer is not configured to start from a CD or DVD, check your BIOS settings.
  • Click Repair your computer.
  • Select US as the keyboard language settings, and then click Next.
  • Select the operating system you want to repair, and then click Next.
  • Select your user account and click Next.
On the System Recovery Options menu you will get the following options:
Startup Repair

Thanks for the reply Gringo. At this point the computer seems to be running okay and virus free after scans using several different programs. Since my wife is using the laptop heavily at the moment I won't have time to rerun the scans and don't want to keep you waiting so let's go ahead and consider this one closed for now.
