• Update Microsoft Security Essentials removed

  Original title: Microsoft Security Essentials

  I use Windows 7 and Office 2007.  Microsoft Security Essentials asked me if I wanted to update the program.  The updated program was a digital signature from Microsoft.  Everything seemed to go well and when the download is complete, it asked me to restart my computer.  After the restart, Security Essentials has completely disappeared from my computer.

  If that's the problem with Microsoft Security Essentials, then try to install it from:

  http://www.Microsoft.com/security_essentials/default.aspx

  Also, check in the start menu and see if you can open it or not

  And if still problem then contact support:

• Update (error code 80070103) Windows Update fails & Microsoft Security Essentials does not install (error code 0 x 80070643)

  I keep trying to update and all these errors reappear. I can't install Microsoft Security Essentials and any update of Windows. I tried to do system Recoery by pressing F11 after reboot, and it does not work either.  I'm guessing that something might be wrong with the registry or there is a virus but I am not a computer wiz. I don't have the Vista recovery disc and the original disk to restart.  is it possible to fix this?

  I paid to get it to format in November 2010... I installed a fake Windows Vista on it (32 bits but my PC on a 64-bit password) so I had to clean install it.

  I don't understand: If you paid someone to format the HARD drive and do a clean Windows, when install I YOU "installed a 32-bit Vista?"

  If your parent friend had lost the Windows CD comes with the brand new computer, the person you paid use to do the clean install of Vista 64-bit?

  I do not see KB948465 in installed updates, only KB956250 & KB256506

  I asked only KB948465. In any case, KB256506 is not an update or a section of the play.

  No, I never had any other than Microsoft Security Essentials antivirus

  Again, I don't understand. If you have never had any other antivirus MSE and MSE has been installed since November 2010, why you try to 'install Microsoft Security Essentials' now?

  Q: which, if any, of these updates ARE LISTED in updates installed (no update history)?
  A: See the number 3, I don't see anything else apart from those two

  What "number 3"? You see nothing else, in addition to the two updates to date?

  I give up. I can't help you if you do not answer my specific questions in your very next answers!

  I think you'd better take the computer back to the repair shop & pay to figure what's wrong (yet). Good luck.
