Viruses and worms
1

Hi,

Avast is continually warning me about a malware called 800000.cb@.

It seems to be operating as part of windows services.exe

I’ve attached the OTL, MBR, and MBAM scan results to this message.

Any help you can give me would be greatly appreciated.

Thanks for your time

After reviewing your logs, I am going to refer you to our Certified Malware specialist, named Essexboy. He will also review your logs and give you further instructions, however he comes on the forum late UK time. He will respond to you in this thread, so remember to check this thread daily.

Please do not make any further changes to your machine after you have provided the logs.

IMPORTANT: If you are on a home network, disconnect the affected machine from the network. Do not share a USB/flash drive with this affected machine. Do not use this machine unless Essexboy or another malware removal specialist instructs you do to malware removal instructions; use a different machine to check email, sync your phone or other devices.

Let us know if you have any questions. Thank you.

Hi,

I followed your instructions and it seems to have gotten rid of the problem. One thing to note is that OTL froze after a few minutes 3 times when i ran it (including once on safe mode), after restarting the computer however and starting OTL i received a message telling me that files had been deleted so i assume that the freeze happened after the work was done. Regardless i’ve had no virus alert since.

Thanks a lot for your time and effort.

This is a great service,

Cheers

PS the log files are attached

I still need to replace services to finish the job

  1. Close any open browsers.
  2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
  3. Open notepad and copy/paste the text in the quotebox below into it:
FCopy:: c:\windows\winsxs\amd64_microsoft-windows-s..s-servicecontroller_31bf3856ad364e35_6.0.6002.18005_none_2d69d4f782c83d8c\services.exe|c:\windows\system32\Services.exe
Save this as [b]CFScript.txt[/b], in the same location as ComboFix.exe

Refering to the picture above, drag CFScript into ComboFix.exeWhen finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.
