Uninstalling Norton 360 makes Blu-Ray Drive disappear?

On my custom-built rig here; specs in the flyout below. I got a new Norton Anti-Virus 2012, so I needed to uninstall my expired Norton 360.

When I did, however, somehow that's caused my Blu-Ray Drive (ONLY optical drive), AND all of my MagicISO virtual drives, to lose their drivers. I system restored, tried again, & they disappeared again. I re-imaged back to July, and it disappeared AGAIN.

It shows in Device Manager with an exclamation mark, but nothing seems to help. When I try to reinstall the driver (I made an iso of the BRD's installation disc), it says it cannot find the hardware & therefore cannot continue.

Now, WHY on Earth is this happening? I'd imagine my optical drive should have nothing to do with uninstalling Norton 360. Most importantly, HOW can I fix/get around this?

Found it, and while it seems so iffy, this did work. For others' future reference, since over 10 years I've come to realize that un/installing Norton likes to do funny things:

• I don't think you have to restart right off the bat. I didn't.
• Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E25-11CE-BFC1-08002BE10318}
• (May want to export this selection as a backup; I certainly did!)
• Select "Lower Filters," right-click, and delete.
• Select "Upper Filters," right-click, and delete.
• MUST restart.
• Drive is back, like nothing ever happened.

Curse you, Norton. Such a wonderful ally. Switching versions? Can be your worst nightmare. And yet we love you?

They've always been the best for me. On the computers I've had, if they were up to date, they never had a single problem. I've found nearly every part of every program & version easy to use & configure. I only seem to have troubles when I happen to switch from the regular Anti-Virus, or Internet Security, to 360, or vice-versa. For the other 364 days a year, I love it. =)
