Bandwidth consumption problem

    Hello, I was hoping to get some help here. There is something consuming large amounts of bandwidth on my father's internet connection. We suspect it started some point around a week to ten days ago when a bad link or two got activated. I'm a college graduate student home for the summer, and it's my main job to get this fixed. I've tried several things, but it still hasn't solved the central problem. I had luck here, on this forum, a couple years ago so it seems like a good place to try again.

    This bandwidth problem is espeically problamatic because my parents live in a rural area where standard broadband is not available. My father has a hughes net connection with a 550 meg cap. Whatever the problem is currently, it is using upwards to 200 megs a day on its own whether it is idle or not. Perhaps this problem wouldn't even be an issue on a starndard broadband connection, but it is in this case.

    The first suspect for the problem was something called sdra64. We got it successfully removed and through the use of other virus scanners and adware scanners, removed a lot of other stuff; however, the bandwidth consumption remains. Even now such programs as malwarebytes and other free utilities are showing the PC as clean. Our spyware scanners aren't showing much either outside the odd cookie or something

    In no order stuff that's been ran:

    malwarebytes
    house call
    avg
    avast
    spybot
    adaware

    Our netstat shows, sometimes, several odd connections on it. Addtionally, I will provide perhaps the most odd information via screenshots from netlimiter2.
    There are several open connections coming through one of the svchosts. This is where most of the junk downloading is coming through. Or, at least, I think most of it comes through one of the svchosts.

    Hijack Log:

    Logfile of Trend Micro HijackThis v2.0.2
    Scan saved at 3:56:08 PM, on 6/23/2010
    Platform: Windows Vista SP1 (WinNT 6.00.1905)
    MSIE: Internet Explorer v8.00 (8.00.6001.18904)
    Boot mode: Normal


    Edit by chaslang: Inline HJT log removed. READ & RUN ME FIRST. Malware Removal Guide sticky not followed.



    In sum, something is using lots of bandwidth in an unsolicited fashion. It's eating up the bandwidth cap and leading to throttling from the isp. None of our scanners are working at fixing the problem. Even a system restore to a month ago did not fix the issue. This is my last attempt at fixing it before a reformat so I hope you folks can help.

    Thanks.

    Welcome to Major Geeks!

    Please read ALL of this message including the notes before doing anything. Also make sure you observe the instructions about having only one antivirus program installed since you have more than one ( AVG and Symantec).

    Please follow the instructions in the below link:

    READ & RUN ME FIRST. Malware Removal Guide


    and attach the requested logs when you finish these instructions.
    • **** 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. MGtools will frequently run even when all other tools will not.

    • After completing the READ & RUN ME and attaching your logs, make sure that you tell us what problems still remain ( if any still do )!
    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 boot 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 and Malwarebytes ( 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. If you cannot seem to login to an infected user account, try using a different user account (if you have one) in either normal or safe boot mode and running only SUPERAntiSpyware and Malwarebytes while logged into this other user account. Then reboot and see if you can log into the problem user account. If you can then run SUPERAntiSpyware, Malwarebytes, ComboFix and MGtools on the infected account as requested in the instructions.
    4. To avoid additional delay in getting a response, it is strongly advised that after completing the READ & RUN ME you also read this sticky:
    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.
