I am trying to scan my computer with Microsoft Security Essentials, but an error pops out stating that it couldn’t scan my computer. My computer is up to date so I really don’t know why the error is showing.
The error code is 0x8050800c.
What should I do to fix this?
Microsoft Security Essentials

An unexpected problem occurred. Install any available updates, and then try to start the program again. For information on installing updates, see Help and Support.

There’s no problem with the real-time scanning of Microsoft Security Essentials, the status says that your computer is still protected. Your only problem is when you are doing a manual scan of your hard drive. Try following what is suggested in the dialog box. Update Microsoft Security Essentials. If updating the software did not help, try checking its settings. Make some changes on the settings. Do a trial-and-error in changing the settings to isolate the problem.
If disabling and enabling some options did not give a good result, try uninstalling the application. You can still download it again from Microsoft’s website. When the application is completely removed from the system, check your computer for any possible errors. Use a disk utility application to check the system. For a much thorough diagnostics on the system, use a disk utility application like Norton Utilities or Norton SystemWorks.
If you still have the installer for Microsoft Security Essentials, install it then try doing a scan again. If you don’t have the installer, you can download it at http://www.microsoft.com/en-us/download/details.aspx?id=5201.
