• How can I remove/uninstall Microsoft "Search Enhancement Pack?

  This program is always displayed as a start-up program. How can I remove it. Thank you

  Hi Nick,

  Go to http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx and run Autoruns and click all.  Look for everything related to the development of research pack or maybe the Windows Live Toolbar or Windows Live or Windows Live Search Toolbar add-in (I've read can be the source of the present) and when you find it uncheck the box to prevent it from start to start.  Check the entire list as there may be several entries.  When you're done, click OK and restart.   The program must start is no longer at the start (but it will still be on your system, if you ever want to use it).

  If you really want to unininstall the "program", recogning it can be uninstalled more that just the pack of development of research, but also a toolbar or an add-in, go to start / Control Panel / programs and features and searching for it (it can be called something different as the above options check all the installed programs).  If Yes, click on it and choose uninstall or remove and then reboot and that should be that. To be honest, if you got out of the above startup programs, I had probably lleave alone - but it's your decision to make if she's not there, if not, then go to installed updates and check here to see if you can find it (but I don't think it's an update installed, if I'm wrong).  If Yes, then you must decide if you want to really uninstall an update or not-, I would check the KB article to see the consequences before you do.  Once again, to be honest, if you guessed start above, I would probably leave - but again, it is your decision.

  If it is not displayed as an update or a program, download Revo Uninstaller: http://www.revouninstaller.com/revo_uninstaller_free_download.html and see if it detects the above names or something similar to uninstall. If so, uninstall it in Advanced Mode and that should solve the problem.

  Unless that has changed recently if you don't see it in Add/Remove or Revo, then click on start / all programs / administrative tools / right-click on command prompt, and then click Run as administrator.  (If you use XP, you can use Start / Run instead).  Then paste this line and press enter msiexec /x {9C9CEB9D-53FD-49A7-85D2-FE674F72F24E}. Reboot and see if that helped.

  If this does not work, try that same process in the previous paragraph, but instead, use the command msiexec /x {299CF645 - 48 c 7-4FA1-8BCD-5CE2200CF180D}.

  I hope this helps.

  Good luck

• How 11g Forms Builder to decide on its name of registry key?

  Does anyone know how Oracle 11 g decides on the registry path?
  
  As we have a common configuration to all developers for their code, it would be nice to have a standard excerpt from the registry (.reg file) with the FORMS_PATH already installed.
  
  However, where 10g is always done KEY_IDS1012 on each machine and you could import a .reg file standard, 11g does something like KEY_OH586109512 which is different on each PC.
  
  Is it possible to perform 11g use a common registry or work key what is the key? -It looks like a random number for me.
  
  TIA
  Steve

  Hi Steve,.

  You can find the name of the registry key in the file -\bin\oracle.key
  If the scripting language of your choice, you can read the key from this file and replace in the .reg file to import on the PC. We used it to automate customization of developer facilities.

• How can I find and repair a corrupted registry key

  How can I find and repair a corrupted registry key

  It would be useful to know a number of facts that you forgot:

  1. Windows version, including service pack
  2. Your HP printer model
  3. The error message that you initially received which led you to try the FixIt
  4. The web address of the FixIt tool you tried (NOT FixIt Center home page, but the page where you downloaded or run the FixIt tool).
  5. The full text of the error message on "registry keys corrupted MSI.

  That being said, it seems that if you have installed and then try to uninstall any software related to the printer.  If this is the case, and the printing software cannot be uninstalled from Control Panel > Add / Remove Programs, you can use either the Utility Microsoft Windows Installer Cleanup or (free) Revo Uninstaller.

  Truth in advertising: you may notice that the link to the Windows Installer Cleanup utility is not a Microsoft site.  It's because Microsoft has removed it stating that he sometimes 'cleaned' more that she was supposed to.  Personally, I would use it again, but I would back up the registry first of all, with a restore of the system or C:\windows\eruntpoint.

  After that you have uninstalled whatever it is, you have tried to uninstall, see instructions here: Article 1

• Ethernet and Wireless NIC inoperative; can not be uninstalled; It comes after virus removal

  After a virus removal, which did not seem to remove the files that would make this kind of problem (in fact he only renamed infected files), my Broadcom network to the ethernet port interface cards (1) and (2) wireless networks and (3) nVidia network controller are inoperative.  (Exclamation point in Device Manager under Network Interfaces error 39 ' no driver not loaded"of course; all implemented by a device MS_PASSTHRUMP driver).  The system is a laptop running WinXP SP2 (with its double chips AMD processor THAT XP SP3 installs successfully not when I tried it).

  Just by the way, the virus scan from a Linux bootable CD based, which seems to be a great idea to prevent some nifty behavior that virii have evolved until today, when they can actually run out of danger.  I wish I knew why the renaming of non-critical files where virus signatures have been found could cause this kind of problem with all the network adapters on the system.  The only linked folder links to networking was in the HP wireless Assistant and I have always used the Windows installation for the control of the wireless connection. (More later on this scanner).

  Additional verification shows that any problem 3 NICs have 'pilot' charged by Windows (if you ask "Driver Details").  For 2 of the 3, there is another very similar device (the exception is the driver of the Mini IP WAN), with their drivers loaded, from which you can determine the driver files.  All driver files are present (especially in the Win/Sys32/Drivers/folder of course).  Non-working devices have all "»" added to their names, to be a unique name, I guess. "  Windows seems to ignore the other copies for use, but does not seem to deal with the extent of their drivers OK loading.

  I tried to disable the problem devices and reboot, but that solves nothing.  If I try to uninstall any of these devices of problem (so that they can be reinstalled?), this operation fails, a message "failed to uninstall; may device is used for the start. "  There is a boot in the BIOS of the ethernet option, but that is disabled in the BIOS.  I wonder if these three devices have been added by the virus as a "shell" around actual devices and drivers for viral use?  If so, just be able to remove the devices of hull could them might solve the problem. with the exception of the hooks, they could have placed in the original device drivers.

  I also tried to reinstall these devices from the files of data recovery of manufacturer (HP) and that seems to unfold, but does not change anything about the netwrok connectivity.

  Things work to the point that a ping to itself (127.0.0.1) succeeds, so stack IP seems to works, but trying to ping the gateway router (which connects the laptop), fails - I used the ethernet (wired) connection in time.

  Tried to go back to a previous restore point, but who also does not work.  The Windows shell commits a violation of memory protection (each time) when you try to restart using (any) previous restore point, so the system restore undoes any changes he might have done could have fixed the issues above.

  Many details above.  I am looking for no idea regarding: (a) what could happen here, (b) how the network problem cards make installable again to get rid of them, (c) any other thing that might apply.

  Thank you.

  =======================

  November 5, 2009

  Problem solved.  Here's how.

  The blackout "Network Interface Cards" were virtual devices, created by the Virus.

  Steps, I made before the previous post (above):
  (1) unplug the machine infected of all access to the internet.
  (2) on another computer, I went to http://www.free-av.com/, click on the download tab and under "Free tools" at the bottom, chosen Avira AntiVir Rescue System.  Then I downloaded it, run, and it burned a bootable "rescue CD".
  (3) has taken the CD for infected people kicked and machine from him.  If you cannot open your CD with power off, another way is to start the system, insert the CD, then restart the system.  Pay attention to all messages early in the boot process before Windows loads.  Depending on your system configuration, you may need to change the boot sequence so that the CD drive is checked before the hard drive.  It's usually pretty easy to do, once you pressed the right key during startup to indicate you want to take control of this small point.
  (4) I forgot the exact option here once the CD boot system, but select that you want to run the virus scan.  It took about 2 hours on my laptop.  The initial default is report results only; I suggest to change that to rename infected files (which will add an XXX at the end of any "infected" file).  The analysis is quite complete, but can be overagressive at times.  It is not a complete scan, given that the big Compact files assessed completely.  Recording on paper for future reference: all of the alerts that were generated, the path and name of the file and the reason for the alert.  Some will probably be partial matches to the viral bosses identified as 'contains a model of detection' (a partial match suspicious), rather than 'contains the threat XYZ' (which means that all paired for identification).  Some of the files "suspicious" may be essential to the operation of your system and you want to UN-rename them back to their original name.  If in doubt, check with someone who knows the PCs.
  (5) now you should have a system contains it a neutralized virus to work for removal.  That's where I was when I filed the report.  My major issue remaining before cleaning the pieces of virus, which was now there is no internet access, no cable, no wireless on the infected system.

  OK, so what next?  My infection cause a virus named ndisvvan.sys driver.  If you also have this bad actor, then you may want to read in detail.  If not, then the following may, or do not apply to your case.

  (6) first, in Windows Explorer (let us remember that we are in Win XP), click on tools, then Folder Options... and select the view tab.  Go to the bottom of the list and select "Show the hidden files and folders" and uncheck "hide the file Extensions known Types.  We will need to go into the hidden folders and know exactly the type of file that we deal with.  I guess it goes without saying that yu has to be a system administrator for what to do next.  Win Vista it makes it much more difficult, since sometimes the administrator has no access to all the files that have been installed by a different administrator ID.  It must mess with you give permission, or appropriate, the files you need to access.  I suggest to make a new folder ("VirusParts") to store all the files that you find on the virus, until you are ready to delete them forever.
  (7) first of all, open the file C:\Windows\system32\drivers\etc\HOSTS (now called HOSTSXXX) and move this file to your VirusParts folder.  This part of your internet access is now unlocked.
  (8) then go to C:\WINDOWS\inf, and browse for the files netsf.inf, netsf. PNF, netsf_m.inf and netsf_m.PNF.  These are the files that most likely loading drivers virus in your system.  Having a peek inside .inf files can help you identify some of the changes made by the virus to your registry.  The virus probably also created a new service on your machine.  In my case, the service was named Passthru, and device to implement ms_passthrump (Microsoft Passthru Miniport).  These names are actually from a document from Microsoft that explains how to develop programs of virtual device to filter the data goes or network devices.  If these are directly related to your virus, the program driver specified inside them will be none other than our ndisvvan.sys enemy.  Research in .inf files (these are files text; the.) The PNF files are binary, not text) can help identify the service or services that the virus added to your system, which are now (essentially) a part of the operating system that starts automatically with Windows.  Since there is no virus in the .inf or the. The PNF files, they will not be detected by an antivirus.  All .inf files sort in order of the date and time of creation.  Suspect not with a close date of one of the files netsf.inf and netsf_m.inf.  Windows compile .inf files in the. PNF files, which can occur a few days later, when windows moves to this task.  If you find these files, move them to your VirusParts folder where they can not be recharged.
  (9) to start the Panel (from the start menu), double-click 'System', then select the Hardware tab, then click the Device Manager button.  Expand the category of Network Interfaces, and some of them should have an exclamation point in a yellow circle showing.  If you right-click on each one and select Properties, you should see an error 39 (driver not found; the antivirus program renamed their ndisvvan.sys file).  If you click on the other tabs in the properties, you can find the device is something like ROOT\MS_PASSTHRUMP\0000.  Now, you know that you are very likely to something.  I had three devices affected with numbers 0000, 0001 and 0002.  Carefully note the names of the Network Interfaces.  Two of my friends were identical to the names of other Interfaces of network but with "»" added.  The interface of third-party network with a problem was named 'Miniport network EXPANDED (IP) -'.  But there is no corresponding legitimate network interface of the same name.  Common Council to recharge a bad driver is uninstall, no new hardware detection and let windows reload from .inf file specifications.  However, if you try to uninstall these interfaces (those with here in exclamation points) Windows tells you that they can't be uninstalled and "perhaps it is used to start" or other similar term.
  (10) this part is a bit tricky.  Ask someone who knows how to work with the Windows registry, if you're not on this topic.  Mistakes here can have disastrous results.  Enough said?  If you search the registry for "passthru", you will get several matches, mostly related in one way or another for the virus and his new 'service '.
  Under a path like HKEY_USER_MACHINE\CurrentControlSet\Enum\Root\MS_PASSTHRUMP\0000, you will find information as the name of the interface (make sure it matches the name that you noted earlier) and manages a definition of tha of the pilot program.  For example {4D36E972-E325-11CE-BFC1-08002BE10318} \0014.  Do the same for MS_PASSTHRUMP\0001 (probably {... (10318} \0015) and \0002 (probably {... (10318} \0016).  The string of numbers and letters within the {...} identifies a particular program for windows, and the \0014 a particular use of the program {... 10318} is actually a standard part of windows and not a part of the virus.  However, uses \0014 \0015 and \0016 of this program have probably added by the virus.  Save the links: MS_PASSTHRUMP\0000 related to {... 10318} \0014.  Now, go to HKEY_LOCAL_MACHINE\CurrentControlSet\Class and you will find a long list of class programs identified by their number {...}.  I suggest from the end of the list and the expansion of each occurrence of our {... 10318} in the list, one by one.  If you select the subitems in the extension of this list, each device has a name.  You are looking for Netwrok Interface devices.  Under the instance of our {... network interface devices 10318} it will be to the less 0014 points and probably at least 0016 (based on the links that we just recorded). 0014 resembled a legitimate wireless LAN interface, so I don't mess with this definition.  However 0015 and 0016 looked like they have been added by the virus.  Inside of each specification, you will find a key named "characteristic".  Its value is what prevents us from uninstall the network interface in the Device Manager.  Its value is a hexadecimal value that integrates several indicators for Windows.  In particular, the value 0 x 20 is the bit that specifies that the device cannot be uninstalled by the user, and 0x08 tells windows ' hide ' this device of the user.  Almost all of my devices had characteristics codes 0 x 29, including those created by the virus.  (I don't know; others might have been modified by the virus, but that seems a bit unlikely).  In any case, for the interfaces added by the virus, network we need to change their characteristic values of 0 x 29 something like 0 x 1 (you can also display the device).  Note that changing the characteristic value is a reversible operation that is likely to harm anything in the system.  We can always go back and change it back to 0 x 29, if we have not uninstalled the device.  In my case, I put the characteristics values on 0 x 1 for 0015-0016 devices, which looked like, they were added by the virus.  I did this in the CurrentControlSet control set and for good measure repeated it in ControlSet001 and ControlSet002 registry.  (Windows retains backups of critical information in the registry, in the different ControlSets and creates the CurrentControlSet Control at the system startup set.)
  (11) now return the Control Panel, then system, then the Hardware tab and then the Device Manager button.  Now you should be able to uninstall the network with exclamation points interfaces in the yellow circles, those we checked earlier was connected to the ndisvvan.sys driver of virus, using the MS_PASSTHRUMP interfaces for Passthru Windows service.  Since it's virtual devices, and we removed their .inf and. The PNF files, they're not coming after we uninstall them.
  (12) now, we have removed the network interface drivers that are added by the virus, but legitimate real pilots are not connected in the system correctly, so our internet connection still does not work.  We need to re - install the drivers of legitimate network interface.  To do this, in the device, right-click Manager and uninstall the device controller network legitimate.  On my HP laptop, it was named "nVidia nForce Network Controller".  After uninstallation, in the window menu in Device Manager, click Actions, and then select "Scan for hardware changes".  Windows should report that she has found a new network interface device and that it is set up, and in a minute or two, it is ready for use.  At this point, on my system, both the wired ethernet port and wireless LAN bustled again.

  I still have to go around cleaning the files renamed by the antivirus program and get them out of the PC, but at least the PC is now working without virus.  The virus may also have damaged the process of restoration of the system, which still fails to restore the previous system configuration.  (Windows Explorer always creates an exception address on reboot).  I still need to work on this problem.  The virus 'off' system restore for all drives by using a parameter, however the TWEAKUI tool (I think it was what I used) allowed me to override this setting and control of group policy.

  There are a lot of viruses out there who adopts this method to take control of low level of connections from the PC to the internet, while allowing to download more viruses and keyloggers in the future in respect of the remote control.  Some of these viruses attach also to the many many files the user program.  In this case it has little alternative except to wipe the drive and start over with a clean, install since often these files cannot be cleaned.  Fortunately, my infection was not serious, and it was possible to remove the virus as described above.  I hope this description helps somebody out there.

  This answer is just a formality to change the resolved state.

• Huawei has installed a malware during the installation of the drivers for the wireless modem: tips to remove the registry keys?

  Huawei sd usb storage

  Applies to: Windows | Windows Vista | Hardware and drivers

  A month before, I let a co-worker install a modem Wireless USB as Huawei to use my laptop somewhere without wifi service.  Subsequently, I uninstalled the software drivers because I don't think I'll ever use this modem again.

  Now, I noticed that there are several registry keys for different devices of e/s as:
  Huawei_sd_storage_usb
  and
  Huawei_some other drive type

  None of these registry keys can be deleted, I get an error saying that "year error occurred during an attempt to delete the key.  Same thing if I try to write data in the registry key.  This behavior resembles a persistent virus and not a register legitimate supporting a legitimate PnP device.

  I then rebooted in safe MODE, thinking which should pick up anything the malware is hung.  No go, same thing, cannot remove the key and cannot modify the data in the key.

  None of the malware scanners were able to detect this, including:
  Paid last AVG
  Windows Defender
  Microsoft Security Essential
  Spybot S & D latest
  Malware Microsoft Fixit

  I don't trust Huawei, and what look like these keys are to monitor my laptops I/O activities through any player or the USB port.

  HP DV5t-1000 CTO
  Pentium dual core 2.54
  4 GB of DDR, Home Premium Vista 64

  I'm moving your question on the forum of Windows for material and the Drivers.These are the registry keys related to the legitimate drivers provided by the manufacturer of the device and are not related to malware.

  Note, however, that you have an overload of running security software and some should be deleted. If you use Microsoft Security Essentials, you must disable Windows Defender in Vista and AVG should be removed, preferably using the AVG removal tool. I have no idea what is the Microsoft Malware Fixit.

  You should never have more than one security product installed on the PC, providing active protection / scan. This can cause performance problems, system instability and may adversely affect the effectiveness of these two products to provide protection.

• Install the software and registry keys for the windows installer I screwed up after a system restore, what can I do?

  After you install an update, which forced me to restart my laptop, I had to do a restore point, because it stops while windows is loading files of the update, which led me to a restoration of the system, which has messed up a large number of windows registry keys install leaving me unable to open the following software:

  • Skype
  • Avira (but not the antivirus) Launcher
  • Java

  I can not install or uninstall these programs, either because I need to an .msi file that does not match the latest version of these programs, the program does not appear in the uninstall Manager or just installer does not at all, so what can I do to correct these programs and be able to install their return

  The just Java installer does not appear when I double click on the .exe, no matter if it is the x 64 or 32 bits, and I can't uninstall it because it does not appear in the uninstall Manager.

  Avira Launcher Installer, ask me for a .msi to remove the last version, but I can't, if the installation fails, also the program does not appear in the uninstall Manager.

  The Skype installer just cannot be updated, and I uninstalled it with a 3rd party uninstaller, but now it's just throw a critical failure when starting to install

  My main question is, how can I solve these installers, should I format this laptop and do a clean install of windows?

  Hello

  Please contact Microsoft Community.

  After the description of the problem, I understand that you are not able to install programs after system restore.

  In this case first I'd say allowing you to run the cities in trouble it automatically repair the issues that block the installation program or delete because of corrupted registry keys.

  https://support.Microsoft.com/en-us/mats/program_install_and_uninstall?WA=wsignin1.0

  After that it fixes if you have any third party anti virus try to disable it from your computer and then try to install these programs.

  WARNING:

  Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to 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, while your antivirus software is disabled, your computer is vulnerable to attacks.

  Try these steps and ley, we know the results.

  I hope this helps.
