Impossible to connect to internet error C:\ProgramData\perfkill64.dll could not be started

Original title: what is perfkill64.dll?

My aunt has a PC Windows 7 Home Premium, I tried to restore access to the Internet.  For some unknown reason, he absolutely refuses to connect to the Internet.  IPCONFIG reveals a valid IP address assigned by the modem.  However, I can not navigate to the modems of the user interface through the gateway address.  I rebooted the computer and the modem, disabled and enabled NIC, flush DNS, try IP assignment for the NETWORK card, released and renewed the INVESTIGATION period, turned off all firewalls (windows and McAfee) but nothing I've done seems to solve this issue.

If I boot the system in safe MODE I can access the Internet fine which, naturally, leads me to believe that it's a software problem.  I can't figure out who it is that is blocking access.  The only possible clue on what I have to go is a mistake during the loading of the GUI of Windows after restart, which advises "C:\ProgramData\perfkill64.dll could not be started."  This file does not yet exist in this directory, nor any amount of Google search reveals what could be this file.
I am quite open to suggestions at this point... I'm puzzled.

Hi sigmapi332,

·         What is the full error message?

·         He has already worked?

·         Did you do changes on the computer before the show?

Follow these methods.

Method 1: Temporarily disable the security software .

If you do not disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network during the time that your antivirus software is disabled, your computer is vulnerable to attacks.

Method 2: As the problem does not persist in SafeMode with network, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

Note: After completing the steps in the clean boot troubleshooting, follow step 7 the link to start the computer to a Normal startupmode.

    How can I solve this problem?

    Hi all

    I have a workaround which is a little less boring that the patch "restart the PC": If you get the error where MYOB crashes when you try to send an e-mail, open Task Manager (ctrl-alt-del or right click on the start bar), then go to the "Processes" tab and close all instances of wlmail.exe using the button "complete the process".

    It seems that this error occurs if you have Windows Live Mail opened when you try and send emails of MYOB. If you then close WLMail after that get the error the process seems to never close, so you have to close it manually. If you send all your emails with closed WLMail MYOB it seems to be OK.

    Blue C:\WINDOWS\wmcicif.dll error (Windows XP) specific module could not be found

    My printer kept jamming so I went to reboot my computer and this is the message that appeared and continue to appear each time that I reboot or turn my computer now.

    I deleted and re-installed my printer in the hope that it could solve my problem, however, it did not work.

    It is easy to get rid of the error message by doing something like disable the startup item in msconfig (if you can still find), but I suggest you solve the problem and not only correct the symptoms of the problem in just the startup message.  Deactivation of the item in msconfig 'fixed' nothing but the annoying startup message.
    I would recommend also you start to search in the register, unless you have a backup because there is no 'Cancel' or 'quit without saving changes' option in regedit.  If you make a mistake, that's all.
    These ideas relieve 'rapid' and sometimes risky of the symptom, but may not actually solve the problem.  Also, I'd be suspicious of ideas that begin with the words "try."  You don't need to try things, you need to fix things.
    Here are the detailed instructions that protect you and solve your problem in the 'right' way.
    There is very little. DLL files that should be loaded from the C:\WINDOWS folder and is not one of them.
    Describe your current antivirus and software anti malware situation: McAfee, Norton, Spybot, AVG, Avira
    !, Defender, ZoneAlarm, PC Tools, MSE, Comodo, etc..
    A "Cannot find...". ', ' Failed to start..., "Could not load..." ». "Might not work... "" Cannot run ""error loading... ". "or"specific module could not be found"message at startup is usually related to the malware that has been configured to run at startup, but the referenced file has been removed after a malware scan, leaving behind him a startup item or the registry entry pointing to a file that does not exist.
    It might be a removal of malicious software or an application not installed.  The entry may have a curious looking name since it was probably generated at random when the malware was installed. If you search your system for the referenced file, you may not find.
    Windows attempts to load this file but cannot locate because the file has been deleted for most probably during an analysis of the malware. However, an orphaned associate of remainders of startup parameter or registry entry and tells Windows to load the file when you start or connection.
    So you should delete the referenced entry Windows stop trying to load or run the file. It may or may not be included in the registry, but you can find it.  Autoruns (see below) you get the elements no matter where it is.
    If you just locate and uncheck the item in msconfig, which disables the element but does not remove the reference to the element of false starting your computer.   The msconfig program is not a Startup Manager, that's a troubleshooting tool.  Disabling things in msconfig to put an end to the messages and think that your problem is solved is short-sighted and leave behind him a sloppy XP configuration.  Just disable the display of a start-up error message should not count as a 'solution' to the problem.
    If you are comfortable editing the registry, you can find and remove the reference directly from there or remove it using a popular third-party tool called Autoruns.  The problem can always be found in the registry well.
    Before making any changes to your registry by hand or with third-party tools, don't forget to first make a backup of the registry. There is no cancellation or exit without saving the option in regedit.
    Here is a link to a popular registry backup tool:
    You can use Autoruns to find the element of start remains little matter where he's hiding.  Autoruns does not install anything on your computer.  It will display all startup locations where the reference may be then you can turn it off or remove it completely.  Here is the download link for Autoruns:
    Run Autoruns.exe and wait that he at the end of the filling of the list of entries.
    When the Autoruns is finished scanning your system, it will say "Ready" in the lower left corner.  Autoruns can be a little intimidating to first if you have never seen it before because it displays a lot of information.  You are really interested only a few sections.
    The problem is usually to start the system or the user startup entries, then click the connection tab and see if the startup item is there.
    Scroll through the list and look for a boot entry associated files in the error message.
    If you can't find on the connection tab, look in any tab.
    You can also click file, search to search for logon, or any tab for all or part of the name of the element.
    Right-click on the offending entry and choose Remove
    .  If you are not sure what it is, you can simply disable, restart and if the problem is resolved and then remove the offending entry.  If you don't see it in Autoruns, you may edit the registry and remove the item from your startup folder it.  Autoruns shall display the same information however.
    Given that you had or have an infection, followed with this:
    Perform scans for malware, and then fix any problems:
    Download, install, update and do a full scan with these free malware detection programs:
    Malwarebytes (MMFA): http://malwarebytes.org/
    SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
    They can be uninstalled later if you wish.
    Restart your computer and solve the outstanding issues.

    I tried to install Windows 7 Home Premium Upgrade, 32-bit version. My current system is an Intel iMac (later), with Windows XP - SP3 loaded as a virtual machine with Parallels Desktop 4.0 build 3848 (according to their website, it is supposed to support Windows 7).

    I allocated enough space RAM and HARD drive of the virtual machine to run Windows 7. No matter what I do, when I try to run setup.exe, I get the error message: "the file 'autorun.dll' could not be loaded or is corrupt. Setup cannot continue. Error code is [0x7E].

    The file 'autorun.dll' is present on the disk.

    I saw on the internet that other people have also had this problem, with or without Parallels Desktop, and get a replacement DVD of Windows 7 program made no difference to them. Nor is it an available answer, I've seen.

    My Windows 7 disc is new, so I was hoping that Microsoft could solve the problem for me?

    Thank you.



    OK, so, this response is a little late to come, but if you never solved...

    I just encountered the same problem - editing similar (Mac, Parallels 5 in my case, the SP3 of XP, MS Windows 7 Home Premium Upgrade) - you must make sure that the DVDROM drive hardware is mapped to "D:" on your XP installation. Thus on the Parallels Desktop menu go to devices, CD/DVD1 and make sure that all your actual DVD player is called is selected (should be the vertical entry in the menu) - not true CD/DVD. The reader should then start and auto run.
    I hope this helps...
