I have a client who accdentally opened an email and was hit with a Zues botnet Trojan. I have reason to believe there is also a rootkit because of the file named xecavay.exe that will multiply. It is running out of file location \AppData\Roaming\Irobsyef. I have run Malwarebytes, TDSSkiller with loaded mods., and finally ComboFix. The computer keep giving BSOD when trying to run TDSS and ComboFix. I would love to supply the ComboFix log but the dog ate it ( I had to maunally restart the computer to finish the scan that I had to exit out of becuase it wouldnt finish.) While I was writing this post a file download wanted to open from cdn.fastclick.net. I only have the TDDSkiller logs.

Hi there,
my name is Marius and I will assist you with your malware related problems.

Before we move on, please read the following points carefully.

  • First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
  • Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
  • Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
  • Stay with me. I will give you some advice about prevention after the cleanup process. Absence of symptoms does not always mean the computer is clean.
  • My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.

I had to escalate this ticket. If the person who solved this for me did some strange way of removal I will be sure to post it. Thanks for the response.

As this seems to be a topic that was started by a commercial IT service, it is now locked down.

We only provide support for private persons or small businesses without an own IT dept.
