    Hi Guys,

    I need your help/advice for the following. My laptop worked fine until yesterday, after a reboot all my browsers (IE 7.X/FF4.X/Chrome 12.0) crash after a few minutes of surfing the web. Usually without a warning but sometimes they show a memory could not be read error.

    Laptop: Lenovo T410, Intel i5, 3 GB ram, WIN XP SP3

    I did the following:
    - Upgraded browsers
    - Disabled/removed add-ons
    - CCcleaner/drive clean etc.
    - FULL Memtest86, and no faults found
    - FULL scans with Spysweeper/Adaware/Mareware bytes (no errors found)
    - Checked PC for strange hidden files/dir/cleaned temp folders

    Then I started checking the processes with sysinternal process monitor and it shows that during the browsing process strange *.dat files are "created". See screen shots. Example:

    Module: asoorloplop.dat
    Path: C:\DOCUME~1\ALLUSE~1\APPLIC~1\asoorloplop.dat
    Description: tGpPj37u M
    version: 4.685.230.0
    Company: lInrjG&b !RKnTN3m

    Of course these files themselves cannot be found or located... but the process monitor shows these items all over the place while running IE/FF/Chrome. It looks like mallware... but I cannot remove it nor can the scan/sweep programs...

    HELP is appreciated :)

    Welcome to Major Geeks!

    Please read ALL of this message including the notes before doing anything.

    Pleases 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.

    true... I took a shortcut... ;)

    SuperSpyware = No fault found
    MG Tool = couldn't complete the check

    so I continued the war against the spyware/malware.

    I was triggered by the stange *.dat files that the process monitor tool was refering too and noticed that these also popped-up while executing other program such as office applications. It looked like the malware was trying to cause a memory overflow that would eventually lead to a crash.

    Hence, I had to find and remove these files...

    In windows explorer these files didn't exist C:\Documents and Settings\All Users\Application Data\ but while using the command prompt (safe mode (F9), cmd, dir /ah, attrib -h asoorloplop.dat) these files (asoorloplop.dat & polpolroosa.dat) did actually appear to be present on the computer!! I made the files visible in the command prompt environment and deleted the files.

    Reboot and all browser problems, memory errors gone :-D (including the slowdowns I was encountering in MS office)

    NICE! - I hope this may help someone else too. It took me > 8 hours to find the root cause and kill it.

    You may want to add the process monitor tool to the Malware removal toolset, it helped me several times. http://technet.microsoft.com/en-us/sysinternals/bb896645
