I recently updated my computer and parts of the security essentials got moved and some deleted. I cannot uninstall this as it does not show up on the windows uninstaller list. PLZ HELP! I tried installing it again, but it did not work.
Your best bet is a system restore to a point before you updated your computer.
If that cures the problem, you will obviously be offered the same update downloads again, which I recommend you check carefully before deciding whether to install them.
It can also help by installing them one at a time rather than a complete batch all at once.
Go to Start - All Programs - Accessories - System Tools - System Restore.
This will walk you through a System Restore:
