    rundll32.exe multiplies!

      Hi All,


      I am using Wndows Vista with Internet Explorer 9.


      I have an issue which has not been fixed even with McAfee Total Protection. Here it is:


      Suppose I have couple of browser windows (IE 8 or 9) open and used. When I close the last browser window (IE 8 or 9), a process called rundll32.exe starts and it multiplies in seconds. They absorbe memory and process power and eventually make the computer stops responding. I tried to remove this thru McAfee Total Protection; no luck.


      An image of the situation attached.


      Anybody knows this issue and a remedy? Thanks All.


      with regards,

          OK you show 2 there is that all you get?


          In case it is an infection run the following

          Update your dat files and scan your PC with Virusscan in Safe Mode.


          To do this, tap F8 repeatedly while booting up. You'll get a boot screen with choices. Pick Safe Mode. Your PC will boot in a low resolution state as most processes won't be running. Go to "MyComputer" (XP) or "Computer" (Vista), right-click the hard drive and select "Scan" from the drop-down menu. You'll see an extra taskbar icon which will show a progress report if youhover over it.


          Then do  the following :

          - Run the free Mcafee Stinger program from http://vil.nai.com/vil/stinger/ -


          Download here latest version of mcafee tool getsusp https://community.mcafee.com/thread/32269

          Before you use Getsusp, you should go to this document and also add your email to preferences


          and download the PDF file explaining what Getsusp is and how it works, and this document


          which downloads the installation guide PDF document.


          If you want another opinion, or to be on the safe side, then you can do a scan with the free versions of these tools :

          Malwarebytes and SuperAntiSpyware

            I know for a fact that when you open Google Chrome with multiple tabs, you get another Rundll,


            However, it does not use 50% of the CPU.

              When Internet Explorer closes down, rundll32 kicks in to perform any clean-up tasks that you've specified in the IE browser settings - deleting temporary files, cookies, add-on data and so on. It should complete those tasks within a short space of time unless you've got a lot of browsing data to delete. If you've got two instances of IE open you'll have one instance of rundll32 for each.


              You seem to have a problem with excessive memory use and/or processor time. What's your operating system and version, how much RAM have you got, and what's your processor speed?


              I'll have a look in the Microsoft tech forums for anyone else who's reporting this.
