It sounds like you will need to reinstall your OS, Try to start your computer with the original DVD that came with the computer, holding down the "C" key while the computer restarts, I see in your statement that you did this, timing is everything. If you have a current Time Machine back then you can proceed to format your hard drive with disk utility and then install Mac OS X on the hard drive then use Migration Assistant to transfer your data from your backup.

Thanks. I actually tried to do a complete erase and reinstall of the OS. What's on the computer is not important, so backing it up isn't an issue. But, the computer just spits the disc out. Any idea why this is all happening all of a sudden?

Something is wrong with your DVD, or your computer's DVD drive. Check the disk and make sure it is clean and is not damaged. And make sure it is a system disk not an update disk, like a Snow Leopard system update disk.

Well done! You've succeeded in turning your Mac into a useless brick.
Deleting the System/Library/extensions folder and the associated manager removed most of the functionality from your OS.
And all to get rid of what sounds like the MacDefender trojan or a variant.
You may have a slim chance of recovering if it will still boot in Target Disc Mode; in which case you can use another Mac to install the system remotely.
And I doubt your warranty with Best Buy is going to cover user "error."

Way to go, alienating someone who knows he messed up even further. Awesome job there. There was absolutely no need for this post at all, other than for you to be feel superior. Happy now?

Boot the computer holding option. When it gets to the grey screen, then try inserting the dvd.
If the dvd is pretty scratched up, it may be as simple as getting another 10.6 installation disk.
