I had this one too, and the fact that Microsoft Security Essentials can't detect it is cause for concern.
#RUNDLL32 EXE WHAT IS IT WINDOWS#
It's easy to confuse this service with the real Windows service "themes". With the file deleted, the service can't hurt you, but you shouldn't have junk in your registry. This deletes the Windows service that was causing that program to run.

In addition to deleting winthemes.dll, you should run 'sc delete winthemes' in a command window. In fact, the only thing I see that they have in common is rundll32 and unwanted processes. That's actually a different worm with different symptoms. In the Windows/system32 folder I found a file called "winthemes_service.dll" I know this is a very old post, but I have had this identical issue for two days and I did find the culprit. I really need help to get rid of this because before I was cool with this and thought it would go away but now I am getting sick of this.
#RUNDLL32 EXE WHAT IS IT PRO#
I have Microsoft Security Essentials and it cant find a virus, also have advance system care which didn't find anything, and I recently tried RegCure Pro but that did nothing at all. Ok so what should I do because like you said there is a rundll32.exe under image path that is running under "C:\Windows\SysWow64\rundll32.exe" The only reason it would be hiding in your app data is if it was actually malware that wasn't able to write itself to the system drive due to security. If you look in task manager the rundll32.exe should always have an image path (if image path is not turned on, select it in View -> Select Columns) of "C:\Windows\System32\rundll32.exe" or "C:\Windows\SysWow64\rundll32.exe" rundll is an important system executable and lots of malware likes to pretend to be it to avoid drawing attention Those look like telltale cases of malware. I would get these BSOD after playing for about 1 hour. I have tryed almost everything I can.Īlso I started getting Blue Screen of Death while playing games like Skyrim and GTA 4. There are two of them that run and each of them takes up like 26-40% of my cpu so that means my computer is running 99% every time these two things are open. When I open task manager this is what shows on the command line: rundll32.exe -o http//::80 -u 123 -p123 -I 1 I can delete these folders and files but they just come back once I reboot my computer.

An example of this folder name is B672.tmp These two rundll files are under my temp files user/username/AppData/Local/Temp and they will be under these two random named folders. My whole computer becomes a pool of heat. As for my processor each core will hit up to 60c and slowly rise. Right at the minute they open up my Graphics Card fan Starts speeding up as my GPU will hit 60C-75C. It will take about 4 minutes for these two to open up once my computer boots up.

Out of no where there are two rundll32's running at the same time once my computer starts up. Out of no where my computer is starting to have some big problems and I want to blame rundll32.exe.
