I just downloaded Combofix and ran it. I got an error saying that I was running Windows 2000 and the software could not work on Win2K.  i am currently running Window 8.1 with all updates on a Lenovo ideapad with Core i7-4500u CPU @ 1.8Gig and 8G of memory.
When I run Malwarebytes then HitMan Pro, neither finds any problems. However, my Browser Chrome Version 39.0.2171.71 m, is running extremely slowly which is usually a sign of it being hijacked. Hence my decision to try and run Combofix.
Can anyone out there help me diagnose what's wrong with my laptop?
Just let me know what files to upload.

This topic will be moved to another area -


Please note that ComboFix is not designed to run on a Windows 8.1 unit, also if you are infected it can do more harm than good. If you are infected, please read below.

For general ComboFix details please see ComboFix usage, Questions, Help? - Look here


You can post to Am I Infected for a first opinion, or follow directly as below. There can be a wait of a few days if the Experts get very busy.


Please follow the instructions in the Malware Removal and Log Section Preparation Guide starting at Step 6.

  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 6 there are instructions for downloading and running DDS which will create two logs. Note: Windows 8.1 Users will not be able run DDS and create a log

When you have done that, Copy and Paste your logs in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team.

Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs or you're using Windows 8.1, then still start the new topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.

After doing this, please reply back in this thread with a link to the new topic so we can close this one, to prevent others answering incorrectly.



Thank You -

That's odd. I've run Combofix on regular 8 with no problem.

People do dumb things. And I'm not talking about paying too much for car insurance either.

:step2: ComboFix System Requirements:

Currently, ComboFix is compatible with:
Windows XP - (32 bit only)
Vista and Windows 7 (32-bit and 64-bit).

Note: Although not listed in the Authorized Guide, ComboFix will run on Windows 8 (32-bit and 64-bit).

ComboFix is not compatible with Windows 8.1 yet so you cannot get it to run...see the review comments on the authorized download page. If you attempt to use ComboFix on Windows 8.1, it should provide a message alert: ComboFix is not meant to run in 'Compatibility Mode' and exit. This message is intentional by design when attempting to run ComboFix on that operating system.

-- if used on Windows 2000, ComboFix will display this message:

sUBs has advised that he is holding off releasing any working version of his tools for Windows 8.1 which includes both ComboFix and DDS. Meaning he is fully aware of the compatibility issue but needs time for thorough testing to ensure they work safely on that OS. As such, no release date has been provided.
