I have a laptop with Windows 8.1 that got infected by rootkits.

Here is what I have already done:

Ran Malwarebytes Full Scan - (see notes below this list)

Ran SuperAntiSpyware Full Scan - multiple times until it found nothing

Ran Avast! Full Scan and Boot Scan - multiple times until they found nothing

Ran TDSSKiller - it found nothing
Ran AdwCleaner - 2 times, second time it found nothing

Ran Junkware Removal Tool (JRT) - 2 times, second time it found nothing

Ran MacAfee Rootkit Removal Tool - it found nothing

 

Notes:

 

At this point, Malwarebytes keeps finding new files, folders, and registry entries during the Heuristic portion of the scan. No matter how many times I run it, it finds them, cleans them, and then they return.

I am suspicious of 2 things in particular

 

1) In C:/Windows/ProgramData there is an UpdateTask folder with a file called vmhost.exe that I cannot delete. Every time I check, the file has been modified within the last hour or so.

2) In C:/Windows/ProgramData there is a MediaDev folder with a sub-folder in it called 1403631292 with a file in it called mediadev.exe that I cannot delete.

 

Would anyone be able to help me?

 

Thanks,

 

Matt

Sorry for the delay to remove the rootkits you will need to repost..

Please follow the instructions in THIS GUIDE starting at Step 6. If you cannot complete a step, skip it and continue.
Once the proper logs are created, then make a NEW TOPIC and post it HERE. Please include a description of your computer issues, what you have done to resolve them, and a link to this topic.
If you can produce at least some of the logs, then please create the new topic and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.
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.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

Thank you!!

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.
Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 3 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
