    I noticed serious performance problems with cpu at 100%.
    Several suspicious files in root; like dn660.exe; shh.exe; eejevkk.exe and some batch files that seem to disable the firewall and then ftp to another site to bring in files. Also in one of the files I found a call to calc.exe.
    What I've done:
    Restored registry twice to earlier dates.
    Booted in Safe mode and deleted visable files.
    Ran up to date scan with Trend Micro - found one file.
    They keep coming back.

    Any body ran across this one?
    thanks

    Please follow the instructions in the READ & RUN ME FIRST link given further down and attach the requested logs when you finish these instructions.
    • If you have problems where no tools seem to run, please try following the steps given in the below and then continue on no matter what you find. You only need to try the TDSSserv steps if having problems getting scans in the Read & Run Me First.
    • If something does not run, write down the info to explain to us later but keep on going.
    • Do not assume that because one step does not work that they all will not.
    READ & RUN ME FIRST. Malware Removal Guide


    Helpful Notes:

    1. If you run into problems trying to run the READ & RUN ME or any of the scans in normal boot mode, you can run the steps in Safe Mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
    2. If you have problems downloading on the problem PC, download the tools and the manual updates for SUPERAntiSpyware, Malwarebytes and Spybot ( links are given in the READ & RUN ME) onto another PC and then burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.
    3. To avoid additional delay in getting a response, it is advised that after completing the READ & RUN ME you also read this sticky:
    4. Any additional post is a bump which will add more delay. Once you attach the logs, your thread will be in the work queue and as stated our system works the oldest threads FIRST.
