Hello All, I have a log of an RKILL I performed, where there are countless amounts of Missing digital signatures, and I have not been able to find any means of fixing this, and I am insom seriously desperate need of help. 

 

I've been using RKill on a almost daily basis with my work and I've never seen anything like this, and I would like to find any means in how to repair this, or if this computer just needs to be wiped and reimaged... Preferably not obviously, but any help would be greatly appreciated.

 

 

It's attached below, but I am at a loss on where to go with this nightmare. Please advise?

On this particular machine, about 6 months approximately, same log more or less, but this isn't my computer. Nothing major has changed, it's an office computer, the user does not have Local Admin rights, so any changes would be logged. I had this same kind of result last time, but as I couldn't find anything on Google or any forums about how to fix this, and after performing a system cleanup and removal of some malware, the computer was working well enough.

 

Recently the system was acting up, and I was contacted regarding it, but I'm trying to see if there's any method to fix this particular type of issue.

Rkill will scan various Windows files to determine if they are signed. If a signature is not detected on a file that should have one, RKill will report it. Rkill will also provide a list of possible replacement files (noted by [Pos Repl] tag) for the file that failed the signature test.

Your log also indicates a number of "Possibly Patched Files" which can be indicative of a serious malware infection.

I recommend further investigation. Many of the scanning we use in this forum are not capable of detecting (repairing/removing) all malware variants so more advanced tools are needed to investigate. Before that can be done you will need to create and post a DDS log for further investigation.

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, post 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, 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 closed this one.
