cannot unregister .dll

I have a .dll file that came as a Trojan horse. It is named 6to4v32.dll. I renamed it to 6to4v32 - old.dll to stop the Trojan horse, but it did not work. My AV don't delete or make changes. He says that access is denied.

When I go to the command prompt to remove it, I'm in the directory and then type
regsvr32/u 6to4v32 - old.dll
I return an error message stating
LoadLibrary ("' 6to4v32 - old.dll" ") failed - access denied.
I tried as an administrator on the computer and the domain. I have also all permissions, but I'm having no luck. Any ideas? Thank you.

Hello

I suggest boot in Safe Mode and run a full scan. If that fails also, the best option may be to back up all the data and reinstall.

Microsoft safety scanner: http://www.microsoft.com/security/scanner/en-us/default.aspx

Note: The Microsoft Safety Scanner ends 10 days after being downloaded. During these 10 days, it will remove all the files infected by the virus and records. I suggest you create a backup of your data, and then install Microsoft Safety Scanner.

  • Satellite A60-723, cannot load DLL files at startup

    Hi, I bought an A60-723 for my education and one day I turned on my pc and it crashed, so I rebooted.

    When I rebooted there are scratches on the screen from the top down. Until the loading screen windows might appear, I had an error that a certain .sys is missing or damaged. I used the recovery cd, but it did not help .sys sometimes a another file was missing (examples: ntfs.sys, setupdd.sys)

    So I decited to format the entire disk. After that the bands would not disappear. And there was no error no that was asked to a bootable cd. So I inserted the windows xp pro cd and tried to install windows.

    While Setup was loading it crashed ad loading of DLL files, and an error has been reported error code 7, as well as another 4 error

    Here is a picture of the scratches that I was talking

    Just found out that if I push next to the touchpad then scratches disappear and I hold up my fingers they come back again: S

    Anyone know what I need to do?

    Hello

    About scratches, put service! There is something of physically wrong with your machine.

    Regarding the startup problem, (do this test before putting service to the band-problem!) first try to use the recovery CD. Retrieve the device and see what happens. Do you find these missing errors file? If this isn't the case, at the same time, cause a little. Try to see if there is a "connection" between the bands and the missing files.
    Get missing files-errors only when you see the scratches? Maybe these 2 problems are really from the same source.
    In this case they should both set if you turn service.

    Hope this helps you.

  • error when pass array 1 d by data in table pointer via Labview-built c++ dll

    I'm trying to generate a Labview VI to a DLL and let it be invoked by vc ++, by which a 1 d array is passed. However, I can't generate the DLL when you use the data pointer to the table, which gives the error like below:

    [ERROR]
    Code :-2147221480
    Strengthening of the DLL.
    Error when compiling the DLL as a function name or a parameter is illegal. Check function and parameter names are legal C identifiers and are not inconsistent with the LabVIEW headers.
    Additional information: 9 project link errors
    Type Library generate error. MIDL.exe failed during the compilation of the odl file used to create the type library.
    Note: The error indicates that the odl file has unknown types. This error is possible when
    works with non-standard types is exported using the method qualifier exporting files in
    release the configuration that have not been recompiled during the build process.

    The Prototype of VI define is as below

    But, if I use the pointer to manage through the table, the generation is successful, error-free. I write something to call the DLL built labview, which basically reads 1000 double the data of an instrument.

    #include "TestDQMaxDLL.h"
    #include 
    
    using namespace std;
    
    int main(int argc, char** argv) {
        cout << "Start testing DQMax DLL" << endl;
    
        int leng{ 1000 };
        DoubleArray rawDPData = AllocateDoubleArray(leng);
        test_dqmax_dll(&rawDPData);
        cout << "Successfully invoked the DLL!" << endl;
        cout << "DoubleArray.len: " << (*rawDPData)->dimSize << endl;
        for (int i = 0; i < leng; i++)
        {
            cout << (*(rawDPData + i))->elt[0] << "\t";
            if (0 == i % 10)
            cout << endl;
        }
    
        system("pause");
    
        DeAllocateDoubleArray(&rawDPData);
    }
    

    But the printed results are not correct.

    My questions are:

    1. why cannot generate DLLS with the data of table pointer. In this case, the argument of the function is as simple as a double array.

    2. for table handle pointer, when the resutls are incorrect and how to get the good ones.

    Any comments would be appreciated.

    BTW: I use Labview 2012 with Visual c ++ 2013 on Windows7 64 bit.

    I never needed to pass a table of LabVIEW handle external code. Search this forum for posts of RolfK, it is most likely to have posted such an example. I recommend that you keep things simple and remodelling your table a table 1 d 2D before moving on to external code and manage as a 1 d table (it's just a little extra math).

    Sorry I don't have a solution on why you can't build with a 1 d as a pointer of table table. If you post your project I'm happy to try to build (I'm on LabVIEW 2012, however), but as you said, it will rely on another machine, it seems more likely to be a problem with something on the specific computer where there is a problem.

  • Error-17004 only when you use CVI RTE

    I am not advocating a solution. I plead for measures of additional debugging I can try to determine what is happening.

    I'm trying to call a function in a built CVI DLLS (INSTR.dll) my TestStand sequence. My DLL linked statically to a second DLL (SYSTEM.dll) including the SYSTEM.lib library in the project of the INSTR. SYSTEM.dll is linked statically to a library of utilities. DLL SYSTEM and INSTR residence in the same folder, and the utility library is located in a folder in the environment variable %PATH%.

    When I put the CVI adapter to run in an external instance, my function work correctly. But when I put the not to run with the CVI RTE (whether through the adapter or the option "Always run In Process", I get an error saying that the DLL cannot be loaded:)

    "Error loading step 'Action' sequence"MainSequence"in the folder"Test.seq". Cannot load DLL or external library 'C:\Temp\test.dll '.

    Code error-17004, could not load DLL or library.

    Source: "THOMAS".

    I tried to use fast (from Windows Sysinternals) and it shows that all my DLLs are found in the course of her probe and are loaded correctly.

    Even if I run the sequence of CVI as "The executable to debug" Editor, I get the same problem. When I do this, I put a breakpoint in my DllMain function and this function is never called.

    If I use a test client executable located in the same folder as the SYSTEM and INSTR, it loads the dll correctly. (But I just realized that the test client is statically linked to the dll INSTR, while TestStand dynamically load the DLL; I'll have to try to change the test client to do this)

    My problem is that I can not reproduce this with a simple set of DLLs, so I can't give an example. I tried to use fast and dependency walker (even if it's expired) and they did not help.

    Someone at - it other ideas or tools that I could try?

    Well, I feel stupid. My project of junior dll and therefore my dll, was named "SYSTEM" (the name was given to us by the customer). And of course, this causes collisions of naming when you try to load this dependency by using the CVIRTE (the development environment must use a different dll loading order).

    I added a prefix file name and everything works now.

    Sometimes, it is more clear what lack us.
