20 thousand rundll32.exe processes after startup

Recommended Posts

20 thousand rundll32.exe processes was the latest I've seen in task manager, have no idea what's causing this on my older PC, I suspect some of my family have been installing things without realizing they contain a potential virus etc, or it could be unrelated but would like to rule that out here. 

My computer is completely unresponsive after ~10-20 seconds from start up in non-safe mode. If I force reboot after a complete lockup, I can get into safe mode with or without networking and use the PC in its limited state just fine, so this is why I suspect it's a virus/hi-jacking software and I'm typing this right now in safe mode with networking.

At first I thought it was a page file issue because when I changed the size of the page file the issue went away, but now it seems to be consistently returning after another reboot since changing the page file and now it has no effect, the computer is useless in this state. 

WIndows 7 64bit ultra

CPU: AMD 8350@stock clocks

Ram: 16GB

GPU: 980ti

HDD: 500GB seagate ---> this could be dying?, it was purchased in 2011

I am able to reformat and re-install windows, i'm just hoping I can save this current windows install before using drastic measures. Thanks for all and any help in advance.

Hello Onepercentand welcome to Malwarebytes,

Leave in Safemode with NW and continue:

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.


Download RogueKiller and save it on your desktop, ensure to download correct version..

RogueKiller (X86)

RogueKiller (x64)
  • Exit all running applications.
  • Double-click on RogueKiller.exe to launch the tool. On its first execution, RogueKiller will disply the software license (EULA), click on "Accept" to continue.
  • If RogueKiller is unable to load, do not hesitate to try launching it several times or rename it winlogon.
  • Click "Start Scan" to begin the analysis. This may take some time.
  • Once the scan is complete, click the "Open TXT" button to display the scan report.
  • Copy/Paste it's content in your next reply.

Do not use the Remove Selected option until i`ve had a look at the log..

Post those logs with your next reply...

Thank you,

Hello again Onepercent,

Yes I thought I remembered your screen name.. Continue please:

Run RogueKiller again in safemode with NW, when the scan finishes make sure all found entries are selected, then use the "Remove Selected" option. Reboot to normal mode...


If your system runs ok in normal mode run the following:

Open Malwarebytes Anti-Malware.
  • On the Settings tab > Protection Scroll to and make sure the following are selected:

    Scan for Rootkits
    Scan within Archives
  • Scroll further to Potential Threat Protection make sure the following are set as follows:
    Potentially Unwanted Programs (PUP`s) set as :- Always detect PUP`s (recommended)
    Potentially Unwanted Modifications (PUM`s) set as :- Alwaysdetect PUM`s (recommended)
  • Click on the Scan make sure Threat Scan is selected,
  • A Threat Scan will begin.
  • When the scan is complete if anything is found make sure that the first checkbox at the top is checked (that will automatically check all detected items), then click on the Quarantine Selected Tab
  • If asked to restart your computer to complete the removal, please do so
  • When complete click on Export Summary after deletion (bottom-left corner) and select Copy to Clipboard.
  • Wait for the prompt to restart the computer to appear, then click on Yes.
  • After the restart once you are back at your desktop, open MBAM once more to retrieve the log.

To get the log from Malwarebytes do the following:
  • Click on the Reports tab > from main interface.
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply

  • Use "Copy to Clipboard, then Right click to your reply > select "Paste" that will copy the log to your reply…

let me see those logs in your next reply..

Thank you,

Hello Onepercent,

Excellent, good to hear your system is back to normal for you. Continue to clean up...

Delete RogueKiller portable from your "Downloads" folder also delete this folder if present: C:\ProgramData\RogueKiller


Download "Delfix by Xplode" and save it to your desktop.

Or use the following if first link is down:

"Delfix link mirror"

If your security program alerts to Delfix either, accept the alert or turn your security off.

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

Make Sure the following items are checked:

  • Remove disinfection tools <----- this will remove tools we may have used.
  • Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created.
  • Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection

Now click on "Run" and wait patiently until the tool has completed.

The tool will create a log when it has completed. We don't need you to post this.

Any remnant files/logs from tools we have used can be deleted…
