Virus/malware ridden laptop, followed removal instructions

By mesomers19 · 7 replies

  1. First off, first time using this thread.

    So here are the problems:
    Internet history says that I have repeatedly visited some site called NDr___ (last couple of letters/numbers always changes)
    Constant Pop-ups
    An alert message that reads:
    Microsoft Visual C++ Runtime library
    Buffer overrun detected
    A buffer overrun has been detected which has corrupted the program’s internal state. The program cannot safely continue and must now be terminated.

    Also internet/laptop runs a lot slower than usual.

    So, I followed the instructions in the
    Viruses/Spyware/Malware, preliminary removal instructions
    and here are my log results that the thread said I should post.

    Side note: I couldn't figure out how to get combo fix to work so I used the second option listed.

    Also, the results of the Panda Antirootkit scan were all zeros.

    NDr - this could mean non delivery receipt, generally used in emails when you send a message and it does not get received or vice versa, good chance your computer is logging into something that is not responding, might be a good thing depending on what that is, have you tried just typing in the letters of NDr___? and seeing where it takes you, even if it is a dodgy site, spyware etc, you will be fine as long as you do not click on anything, even more so if you are using panda and mcafee.

    Buffer over run could be due to a dll problem.

    I have fixed the problem on my P.C. (Win XP Pro SP2, IE7)
    My overun error was caused by a DLL file that is a bad virus or trojan. As a Jpeg file, It was opened by my son on MSN.
    It took me 4 days to work it out. It lives in the windows\system32 folder. I tried 3 spyware programs & Norton Antivirus 2006 but the file kept coming back. I fixed the problem by downloading a Program called PrevX1,at no cost with a trial period of 1 month.

    Go to http://www.prevx.com/
    Download and run it, It worked for me.
    I am sorry I have forgotten the file name but it changes itself a few times.
    My problem caused windows explorer to crash and IE to go crazy at times loading up new pages very fast.

    Another thing you could try to use is ccleaner, a freeware utility, this is available from www.piriform.com, will do a few things which are all straightforward but there is also a registry check, if you have a dll error in there it will find it and give you the option of fixing ( deleting it ).

    For your spyware - adware errors, have you checked your programme list in your control panel - add or remove programmes, if you look down here there is probably something which has installed itself at the back of one of your downloads and hidden away which is causing your pop ups.
    Should be easy enough to recognise, will usually have "ad" somewhere in the file name or be masquerading as a spam blocker or something, lavasoft adaware is usally quite good at finding these things, do not know what firewall you are using but the comodo one is excellent, comodo pro, will do full scan if you choose to get it and will find the virus problem as well as protecting the integrity of your registry, it is also a free download.
    Best of luck

    Ok, first of all some files are missing from Mcafee. You may want to consider reinstalling.

    Looking much better.

    Manually clear cache

    • Open an Explorer folder window (for example, double-click My Computer).
    • From the Explorer menu select Tools | Folder Options | View. Make sure that you have checked the box next to "Show hidden files and folders" and uncheck "Hide protected operating system files".
    • Start Internet Explorer and click Tools | Internet Options | General tab | Settings | View Files.
    • IE should have opened up a folder window, typically viewing a folder with the name of C:\Windows\Temporary Internet Files. Put your cursor in the Address area of the folder window and add the name \content.ie5 to the name, so in our example the Address bar would now read c:\Windows\Temporary Internet Files\content.ie5.
    • You should see a series of folders with random eight-character names like ADOZMZS1. Delete each of these randomly named folders. You may get an error that some files are in use, this is normal if you are currently at a web site since those files are in the cache. Hold down the Shift key when deleting the files so they do not go to the Recycle Bin.

    Download and Run ATF Cleaner
    Download ATF Cleaner by Atribune to your desktop.

    Double-click ATF Cleaner.exe to open it.

    Under Main choose:
    Windows Temp
    Current User Temp
    All Users Temp
    Temporary Internet Files
    Java Cache

    *The other boxes are optional*
    Then click the Empty Selected button.

    Firefox or Opera:
    Click Firefox or Opera at the top and choose: Select All
    Click the Empty Selected button.
    NOTE: If you would like to keep your saved passwords, please click NO at the prompt.

    Click Exit on the Main menu to close the program.

    Uninstall Combofix
    * Click START then RUN
    * Now type Combofix /u in the runbox
    * Make sure there's a space between Combofix and /u
    * Then hit Enter.

    * The above procedure will:
    * Delete the following:
    * ComboFix and its associated files and folders.
    * Reset the clock settings.
    * Hide file extensions, if required.
    * Hide System/Hidden files, if required.
    * Set a new, clean Restore Point.

    Cleanup using OTMoveit2 by OldTimer
    Now we can clear out the rest of the programs we've been using to clean up your computer, they are not suitable for general malware removal and could cause damage if launched accidentally.

    Download OTMoveIt2 by OldTimer OTMoveIt2.exe and place it on your desktop.

    1. Double click OTMoveIt2.exe to launch it.
    If using Vista Right-Click OTMoveIt and choose Run As Administrator
    2. Click on the CleanUp! button.
    3. OTMoveIt2 will download a list from the Internet, if your firewall or other defensive programs alerts you, allow it access.
    4. Click YES at the next prompt (list downloaded, Do you want to begin cleanup process?)

    * When finished exit out of OTMoveIt2

    I recommend you keep
    1 anti virus program
    1 firewall
    Combo of Anti-Spyware (Spybot S&D and MBAM, or your choice)

    For Spybot you can download the latest version from HERE.

    keep them updated.

    You can also turn on tea timer in Spybot:
    • Click on Mode at the top and make sure that Advanced is checked
    • Expand the Tools tab in the left pane
    • Single click on the Resident Icon also in the left pane
    • check Resident "TeaTimer" (Protection of over-all system settings) Active
    • Close spybot

    Also under Tools you can double-click System Startup in the right pane and disable programs from running at startup. This will free up system resources. For example if you don't use MSN Messenger everytime you run your computer you can disable it, then when you want to use it you can launch it through Start -> all programs, or make a shortcut on the desktop for it. That way it doesn't use resources when you aren't using it. Don't disable any entries in green though.

    And just to be sure
    Set correct settings for files
    • Click Start > My Computer > Tools menu (at top of page) > Folder Options > View tab.
    • Under "Hidden files and folders" if necessary select Do not show hidden files and folders.
    • If unchecked please check Hide protected operating system files (Recommended)
    • If necessary check "Display content of system folders"
    • If necessary Uncheck Hide file extensions for known file types.
    • Click OK

    clear system restore points

    • This is a good time to clear your existing system restore points and establish a new clean restore point:
      • Go to Start > All Programs > Accessories > System Tools > System Restore
      • Select Create a restore point, and Ok it.
      • Next, go to Start > Run and type in cleanmgr
      • Select the More options tab
      • Choose the option to clean up system restore and OK it.
      This will remove all restore points except the new one you just created.
