    McAfee won't stay "on" ?

      I downloaded McAfee maybe a month ago and it was working just fine. However, in the last week or so, whenever I open the page it says that "Real-time Scanning is Off" and when I go to turn it on, it doesn't stay on for more than five seconds. This prevents my computer from being protected from viruses, and won't even scan my computer when I click on the scan buttons.

      I'm not sure how to fix this, I don't know if I have a virus or what, or maybe something went wrong with the download. But isn't McAfee supposed to prevent viruses from infecting my computer? I followed a suggestion that informed me to turn my computer on using safe mode with networks, and to scan my hard drive by going through my computer, and it says it scanned it with one item detected and fixed.

      If there's someone who could help me figure this out, that would be great.

          Could you please provide the below information so that we could help you to fix this issue.

          What is the operating system of the computer ?
          Do we have any third party security software installed in the machine ? or in the past ?
          Do we receive any pop ups from anonymous programs (virus alerts) ?


          Thanks and Regards,

            I am having the same problem.  I am operating Windows Vista and do have some other programs running on my computer (Malwarebytes and Ad-Aware).

              Mine is doing the same thing I have Windows 7, the only other thing I have running is windows defender.

                I had the same problem when I downloaded Babylon translator - see above post.  I'm only guessing here, but maybe if a download shares a file with McAfee and if you uninstal the download, as I did, then it messes other things up.

                  Can you all provide me the error that shows up in security center so as we can proceed accordingly. If possible provide me with a screenshot for the same. (that will provide more insight on the issue)

                  Additionally, to speed up the process,

                  Check and delete if you have any other security software installed in the computer.
                  Check and install the available windows’ updates
                  Run MVT from
                  http://mvt.mcafeee.com and post me your session id’s

                    I have recently starting have this issue with my computer, i'm running windows 7 and have not installed any other security software.

                    When i try to switch on real-time scanning there is no error message it just switches straight back off, when i try to run a scan of my pc i'm given a message saying


                    'An unexpected problem occured during your scan

                    Please click OK to go back to the Home page, and then try running your scan again.'

                      Hi, got the same error today with WIN7 Pro. There is a solution in McAfee KB that works for me:

                      You have to change rights of user "system" to full access for  "%Systemroot%\temp" directory.


                      Best regards

                          Cheers for the replys, just to let you know I managed to fix it by scanning userinit.exe, found a few things in there which were removed and the problems gone away since.


                          I haven't ever installed any other security software on my computer and there i had nothing to indicate that i had a virus on here, the first i knew something was wrong was when mcafee told me the real-time scanner was switched off and i was unable to switch it back on, this was the only warning message i received. Windows was also fully up to date as well
