Windows XP- Cannot Open Anything! Cannot find rundll32?

by Jazzbat / April 4, 2011 6:30 AM PDT

I am using Windows XP and I have a problem where when I try to open anything, it goes up to the open with window. When I right click on My Computer, it says it cannot find rundll32.exe. All I have at the taskbar now is the sound, I have AVG and it is not there. Please help! I am desperate and do not want to loose my computer!

You may need to download all of this on a clean computer, copy it to a flash drive or CD, then transfer it to the problem machine..

First, start the computer into "Safe Mode with Networking".. Next, open Internet Explorer and go to Tools-Internet Options-Connection Tab. Click on the LAN settings button. IF there is a check mark next to "Use a proxy server for your LAN", uncheck it. Click OK. Then OK, again.

Next, go to the link below and scroll down to line 12 (left column). RIGHT click on "EXE (lnk and regfile) Fix for Windows XP", choose "Save Target As " or "Save Link As", to download a reg file fix. Save the REG File to your hard disk. Double click it or right click it and choose "merge" and answer yes to the import prompt.



After that, if you can download the tools below on your current computer, and get them to work, then fine, but frequently the problem malware prevents the programs from running correctly. If that's the case, then download ALL of the tools below on a friend or family member's, CLEAN computer and copy them to a CD or flash drive, then transfer them to the problem machine and use them while in Safe Mode.


After transferring it to the problem machine, run the following tool to help allow the removal programs below to run. (courtesy of Grinler at BleepingComputer.com)
There are 3 different versions. If one of them won't run then try to run the other one. Be patient.... as a black window should open, then close after finding all the background programs.
Vista and Win7 users need to right click and choose Run as Admin
You only need to get one of them to run, not all of them.





IMMEDIATELY after running the "Rkill" tool above, run/install the Malwarebytes and SuperAntispyware installer and update files from the links below which you've also copied to a CD or flash drive, and transfered to the problem machine. Do NOT restart the computer after running Rkill.

Once downloaded and before transferring Malwarebytes and SuperAntispyware to the problem machine, rename the program installer "mbam-setup.exe" file to something else like "Gogetum.exe", then copy the installer file and the update file to a CD or flash drive.. Transfer the file to the problem machine, then install the "Gogetum.exe" file, then run the update to get the program current.. After that, run a full system scan and delete anything it finds.

Malwarebytes Installer Download Link (Clicking on the links below will immediately start the download dialogue window.)

Malwarebytes Manual Updater link

Next, install and run a full system scan with the SuperAntispyware program and the manual updater from the links below. As before, you may need to rename the installer file to get the program to install.:


SuperAntispyware Manual Updater

In a few situations, in order for the program to run, it was also necessary to rename the main "mbam.exe" file also after installing it.. It resides in the C:\Programs Files\Malwarebytes Antimalware folder....

And after that, if everything's fine by you can't connect to the internet, then follow the procedures below to check your network "proxy" settings again.

Open Internet Explorer and go to Tools-Internet Options-Connection Tab. Click on the LAN settings button. IF there is a check mark next to "Use a proxy server for your LAN", uncheck it. Click OK. Then OK, again.

Hope this helps.

Grey Post. win for me

one suggestion for those who are in a similar situation. When trying to apply the reg file you may need to manually reassociate the file to C:\windows\System32\regedit.exe. you can do so by right clicking on the reg file and then open with. from there browse to regedit.exe and tick the box for always use this ect. this will then merge the file into the registry enabling exe's to be called correctly. the rest ofhis steps run rkill and then get your malware and AV scanners up and rolling.

Good save Grif!

I had the exact same thing on my Dell.

I'm not sure but I suspect the latest windows update to have caused this, I also hve AVG.
AVG found a threat and vaulted it (which was a randomcharacters.exe) but also vaulted rundll32 in the process. No rundll32 means you can't open any .exe file on your computer, which prevents you from doing anything.

Here is what worked for me:

I downloaded exehelper.com from here : http://www.raktor.net/exeHelper/exeHelper.com
on a different computer and copied it to the "infected" computer with a usb drive.

Nest double click on exehelper and a dos box should appear, run for about a minute and produce a report. This should restore your .exe programs.

having retored this, you can now perform a system restore to a point before the crash happened.

I did this, and then ran malware bytes and AVG and both show clean reports. I haven't had any problem since then.

Hop it helps!
