• When the operating system starts, a window opens asking me to "choose the program you want to open this file: file: rundll32.exe.".

  original title: 'Open with' problem...

  My office was attacked by malware. I have run virus scan and all updates that were available. When the operating system starts, a window opens asking me to "choose the program you want to open this file: file: rundll32.exe.". There are recommended programs and other programs, but I'm fairly certain that none of them are correct. Can anyone help direct me in the right direction to solving this problem? Every program I try to open, translates into an opening by asking the same question, but the file name changes to whatever program I am trying to the window. Thanks in advance for any help.

  Hello

  Just in case there are persistent pieces of malware here is the method of complete elimination.

  is installed.

  Right-click on it and rename it to ZZMbam.COM (or something different than now) and
  Double-click it, and then run it like this. You can rename it back later. Do the same with
  other programs according to the needs. Use this method to others as needed - NOT assume all
  a program deletes all or that it is no other malicious software.

  2.
  Another method is to use them:

  Use Process Explorer to "Suspend" the process will not stop

  Then use AutoRuns to delete the malicious program startup items.

• run missing files rundll32.exe missing. Unable to open many programs

  Infection Trojan horse on Sunday, McAfee detected and removed on Monday.  run missing files missing rundll32.exe can't open most of the programs without having to 'open with' quick screen.  Have tried the solutions to similar problems, without success.  Cannot use the restore system or clickfree. AM running xp service pack 3, any suggestions?

  He hides on your part.

  The dllcache folder is a hidden system folder (normally).

  The dllcache folder is where XP keeps copies of important system files.  Windows file protection monitors these files when your system is working and if it happen never disappeared, PAM quickly and quietly replace it using the copy in the dllcache folder - this is why you put the rundll32.exe file in both places...  One in the dllcache folder is the backup.

  If you want to use Windows search, you need to go to the Advanced Options section and select the search system folders and enable folders and files hidden research.

  If you use Solution Explorer, while you're looking in the c:\windows\system32 folder, you must:

  Click on tools
  Click on the folder view tab Options
  Enable: Display the hidden files and folders
  Disable (uncheck): Hide extensions of known file types
  Disable (uncheck): Hide protected operating system files

  Then, you'll be able to find and navigate in the dllcache folder.

  When you are finished, you can set your options to view back the way they were then you don't have an accident one day in one of these folders.

• File rundll32.exe missing

  Hello!  My problem is that whenever I turn on my computer, I get the error message saying that the file c:windows\system32\rundll32.exe is missing... while booting and I get an error popup saying my firewall prot. is turned off... my automatic updates is OFF... it's just a waste.

  I bought my BB laptop and Windows XP was already installed so I don't have a CD available.  Is there another way? Please email VERY much appreciated! Thank you

  I have two solutions for this:

  1 - C:\Windows\System32 if you can't find rundll32.exe go to C:\Windows\winsxs

  and search for rundll32.exe if found copy in C:\Windows\System32

  Note: display of file Extensions must be enabled in the browser, organizing options

  2 - Use another computer with the same version of xp and a flash drive copy C:\Windows\System32\rundll32.exe in the other computer to C:\Windows\System32 in your computer

• Lost files to exe Apps

  A few days after having installed successfully the Photoshop and Bridge apps for my laptop developed a fault, and after having resolved this issue I can't launch an App as exe files appear to have been lost.  How can I download and install the Apps again? Because I already downloaded apps on my desktop and my laptop I do not seem to be able to download it again.  Any advice would be welcome.

  First try to run the uninstall programs if they are still there. On Windows via the control panel (and Mac OS X from the location of Applications > utilities > Adobe Installers).

  After that, you should be able to re - install the products.

  Only if necessary next run the cleaning Adobe CC, solution 3 to http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation - problems.html. Remove installed products.

  Then try to re - install.

• Windows cannot find C:\WINDOWS\system32\rundll32.exe

  Hello

  Can someone help me, I am trying to open files and folders, and all I get is Windows can't find C;\WINDOWS\system32\rundll32.exe and stop me so gains access. I was told that I could find the file on another computer stick in my memory stick and reapply, only problem I have is I don't know where its located. I'm on windows XP.

  Thank you very much

  Thanks for the suggestion, Lisa!  I tried the link but it says page is more noticed.

  You happen to know any other solution for that darn missing file?  I can't open all the apps in my control panel! ACK!

  Someone found a solution to this problem yet?  Thanks a lot for any attempt to answer!

  :)

  EDIT: I GOT IT!  Browsing the internet, I came across this answer:

  Find a copy of rundll32.exe in the folder c:\windows\system32\dllcache or c:\windows\servicepackfiles\i386.
  If you find it, go ahead and copy rundll32.exe in the c\windows\system32 of the system folder.

  Otherwise you need a windows disk to extend this fichier.* *.

  I have dd a search on my computer for the file "rundll32.exe" and he came in two different folders on my hard drive.  But it MUST be in c:\windows\system32 (file there lack of).  I found the file in the folder dllcache as shown above, then simply copied and pasted in the system32 folder.  And WALLAH!  Problem solved and control panel and all the rest works just fine now!  So simple!  I hope it works for you, the people who are still struggling with this problem!

• Miss me the windows system32 rundll32.exe. I can't access the Add/Remove in the control panel.

  original title: missing file

  Miss me the windows system32 rundll32.exe. I can't access the Add/Remove in the control panel.

  I tried to start - run with my c/d operating system

  I checked for viruses

  I purchase software to remove etc and REG files.

  Now that the devil do?

  Thank you

  If this

  I tried to start - run with my c/d operating system

  means that you have tried to use sfc/scannow from start > run, your experience is not surprising.  This 'solution' is often suggested by people who don't really understand what this command does.  It does not help to restore a missing rundll32.exe file.

  For what is

  I checked for viruses

  What is the name and version of your anti-virus application?  When (approximately) their subscription expires? What other antimalware applications installed?  What other antimalware applications you used recently to scan your computer?

  If you have not yet used the "software to remove the REG files and etc." return for refund or throw it out.  "Registry cleaners", 'tuners', etc. are not useful.  If you used to "clean" the registry, use its "undo" feature (if it has one) to restore the registry.  Longtime MS MVP PA Bear:

  TIP: If you still think again your registry database must be cleaned, repaired, amplified, to the point, healed, twisted, fixed, enlarged, "swept" or optimized (it isn't), read http://aumha.net/viewtopic.php?t=28099 and draw your own conclusions. See also http://blogs.technet.com/markrussinovich/archive/2005/10/02/registry-junk-a-windows-fact-of-life.aspx

  What probably happened is that your antivirus application deleted or quarantined in your file rundll32.exe thinking he was infected.  He could have, but probably not.  In any case, read the post that begins, "That 'solution' is not on my list." in the following thread: http://answers.microsoft.com/en-us/windows/forum/windows_xp-performance/systemrundllexe-not-found/6e30aff2-a88e-4d86-a654-753d54f632d1 you can also read the rest of the posts in this thread.

  Note that c:\windows\system32\dllcache is a hidden folder, but you who type in the address bar of Windows Explorer (or copy and paste), the folder should open anyway.

  Assuming you manage to restore rundll32.exe, download, install, update and run full scans (not at the same time) with each of the following free tools.

• On the computer of the opening, this message: c:\windows\system32\rundll32.exe.

  I searched the drivers and utilities cd that came w/my computer and the operating system cd and do not find this file there.  Don't know what to do from this point on.  Cannot remove programs without this file.  Thanks for any help!

  When you try to open a control panel applet, you see a message like this:

  Control Panel
  Windows cannot find 'C:\WINDOWS\system32\rundll32.exe '.  Make sure you typed the name correctly and then try again.  To search for a file, click the Start button, and then click search.

  If the file is actually missing, it was probably quarantined (actually deleted) by some program antivirus or antimalware you use.

  You might want to reconsider some anti-virus or anti-malware software, you use and whether or not they are effective to protect your system.

  You can look in the c:\windows\system32 folder and see if the file is actually missing or not, but if it is really missing, you must replace it somehow.

  Since the file is one of the protected files 3498 who cares about XP, needed a backup copy of the file on your system in a few other cases.  You must do what the message says and search for the file.

  Click Start, search, for files and folders... and in the search box, enter:

  Rundll32.exe

  The click the search button to search for you the hard drive for a copy of the missing file.

  You can find a copy of the file that is missing in these folders:

  c:\Windows\System32\dllcache
  c:\windows\ServicePackFiles\i386

  If you find a copy in one of these two files, copy and paste it in the c:\windows\system32 folder.  There may be other files rundll32.exe on your system of MS updates, but they can only be those you need (they could work maybe).

  Answered in the affirmative if invited to replace the existing file.

  If you cannot find a copy of the file in one of these two places, there is one on my SkyDrive, you can download.  Here's how:

  I downloaded a copy of XP Pro SP3 file you need on my SkyDrive (everyone has a SkyDrive for file sharing).

  You can download it and when you do, place a copy of the file in these two folders (assuming that Windows is installed on your C drive):

  c:\Windows\System32
  c:\Windows\System32\dllcache (this is where XP keeps backups of important files).

  Here is the link to my SkyDrive and you can get the file you need here:
  https://SkyDrive.live.com/?CID=6a7e789cab1d6f39&ID=6A7E789CAB1D6F39! 311

  When you see the files available for download, you can not see the file extension (.exe, .dll, .cpl, .sys, .zip, etc.), but when download you them they will have the right extension.

  When you download the file (especially if you use Internet Explorer), when you get a chance to save the file, your browser is unable to save the file with an extension (by example, .exe, .dll, .cpl, .sys, .zip, etc) then you will need to manually add the extension appropriate to the file when you download the file before you save it.

  You can download the file without the extension, and then rename the file to add the appropriate extension.  You do not want to use a file called rundll32 when the name of the file should really be called rundll32.exe (if the downloaded file has no extension, you will need to change the name of the file to add the appropriate extension to make it work.

  You then put the downloaded files in the correct folders on your system.

  Note that advice to run sfc/scannow will not replace a file rundll32.exe missing in the system32 folder.  If you need to prove that to yourself, I also have instructions for it.
