    McAfee is crippling my computer , please advise

    Danii

      Hi Folks, (I have Vista32)  ............Several times a week a process goes on that virtually renders my computer unusable for several hours. I am posting a screenshot of the taskbar processes. As you can see the mcshield.exe  is showing 21,302,596 input and output. The light on the computer is always running and it sounds like a train with the fans on high when this is happening. Opening a simple 40kb jpg takes 40 seconds.

       

      There are no scheduled scans in Security Center.

       

      Can anyone tell me how to stop this? When I try to hit "end process in Taskbar....it says it cannot.

       

      Thanks for any direction from anyone with knowledge of this.

          Probably Technical Support can help you more than we can with this type of issue but off the top of my head I would say it's probably either caused by an overstuffed email inbox which it scans periodically - solution put the emails in special mail folders for storage, or it's having a problem updating - it checks every few hours for updates.   Do you have a continuous Internet connection on?

           

          Also is this Vista SP2 and fully updated, including IE9?   Whether or not you use IE that's important because McAfee does regardless of your default browser settings.

           

          Try running the Virtual Technician to see if it finds and fixes anything:  http:mvt.mcafee.com/

           

          If that fails try uninstalling via Control Panel > Programs > Uninstall a Program

          Then run the MCPR cleanup tool and reboot

          reinstall from the online account, not from any CD you may have.

           

          If all that fails contact Technical Support.  It's free by phone or online chat and linked under Useful Links at the top of this page.

            Hello Danii,

             

            Could you please disable Windows Auto-Update and revert if the CPU utilization  is reduced.

             

            Open Internet Explorer > Tools > Windows Update

             

            On the left pane click > Change Settings > Turn Off Windows Updates - Ignore warnings

             

            Please note that the above steps are not a workaround or Troubleshooting  for this issue, just a Test to see if Windows Updates is causing this high CPU usage.

             

            If the above does not help Open "msconfig" and uncheck the unwanted services that start with windows. Please make sure you have hidden the Microsoft services.

             

            Post back with the Outcome..!

             

            Regards

              Auto Windows updates are OFF and have been off for some time. I don't understand what would be "Unwanted services" that start with windows. I am not an IT person.

               

              I do know that this is not a startup issue.............this may happen after I've been on the computer for two hours without any problem and it kicks in and the thing all but freezes.

               

              and Ex_Brit.........I have roughly 5,000 read e-mails in my inbox.....these are already read old e-mails. I keep them because of business. Why would McAfee  "Re-scan" these old e-mails??? I presume they were scanned before they came in.

               

              Thank you for taking the time to answer.

               

              I never use IE....ever.....I use Firefox

               

              Does the screenshot I provided showing 21 million I/O for  the mcshield.exe have something to do with this??............after I posted that shot it went up to 26 million I/O on the taskbar.

                McAfee scans your inbox.  I keep multiple sub-folders for storage, but that's up to you.   I'm only telling you what I've been told.

                 

                You don't have to be using IE for it to be important that it be up to date.   McAfee and various Windows processes do use it regardless of your default browser choices..

                 

                I agree those I/O's shouldn't be happening and I have no idea why they would.   Selvan is best equipped to troubleshoot that.

                    Is that superantispyware the free or licenced version. The licenced version has real time scanning active that will clash with Mcafee. Just a thought.

                      I was wondering the same thing Peacekeeper. After seeing it listed as a (Running) process in the Task Manager screenshot. Opposed to being installed as a "On Demand" scanner. It,s quite possible Danii is

                      experiencing issues similar to what midgefrank was ....just a thought as well.

                       

                      Brrrrrr !!!! It,s (Cold) here in the Carolina,s !!!!

                        SAS is the paid pro version and I guess it is indeed scanning in real time..............It definately  finds things that McAfee does not.

                         

                        How would that make the mcshield.exe have 26 million I/O's though?

                         

                        Thanks

                          The two would possibly compete with each other and cause each other to work all that much harder to scan.   Try turning off the real-time scanning in SAS  and see if it continues after a reboot.
