Hi there,

I've been trying to get rid of this infection for some months now, with no luck.

The infection is very stealth. I wouldn't have noticed it if it wasn't for the unusual, persistent lag that started some time ago, that really annoys me when playing fps online. It made me search for a problem. I found very few symptoms: I keep sending DNS requests for strange names like cfrlam.com or prhnakms.com, etc., to some 13 servers which turned out to be the DNS root servers. I also found that there is some trafic with other computers on other ports as well (like 445 and others). NO firewall would detect any of this traffic (and I tried 5-6 different ones), even when I select a "full internet stop" option, the DNS requests would just keep on going. There are no running programs or services that seem unusual to me, and no anti-virus software found a problem so far. The only thing that sees the DNS packets is Wireshark, and the only scan that found something so far is Gmer, which mentions a mbroot/sinowal infection.

I am getting tired of reading through forums and articles about computer viruses and such, stuff I really don't care to know a lot about. I need help. If I understand correctly, even a format of the two XP partitions might not do any good, if its a mbroot virus.

So I stand ready to install things and post logs. Bare with me and please be patient, as my kids may require more attention than my computer. :-)

Thanks,

igouce

  • 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.
  • Now 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.

IMPORTANT! If for some reason GMER refuses to run, try again.
If it still fails, try to UN-check "Devices" in right pane.
If still no joy, try to run it from Safe Mode.

It looks like you're indeed infected with HelpAssistant Virus (Sinowal).
In this case...

...you will need help from the malware removal team. I would like you to start a new thread and post a DDS log HERE and include a link to this thread. Please make sure that you read the information about getting started before you start your thread.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient. Help is on the way!
