Vista Service Pack Installation Error 80041315

I've tried to install Service Pack 1 via Windows Update several times and it goes all the way through and gets ready to let you restart yoru computer.  It goes through all the stages of installing (takes FOREVER) and then says it wouldn't install and is reverting back.  This also takes forever.  I can't figure out what is wrong.  I am mildly computer literate, but not an IT person by any means.  HELP!

Note: Enable the security software back once everything is done.
Step 2: Download the update to the hard disk (on the desktop).
Step 3: Create a system restore point; look for the steps to create system restore points in the link below.
Step 4: Boot the computer in safe mode, to do this, follow the steps below,
Access the advanced boot options menu by turning on your computer and pressing the F8 key before Windows starts. On the advanced boot options menu select safe mode
Now try to install the update saved on desktop, once the update is installed restart the computer in normal mode and check if the issue persists.
