I got the usual "automatic updates for your computer are now available. Please click here to install updates." So I clicked. "Service Pack 3" okay, must be important! (BTW, I use XP)

And ever since I've been having troubles =[

Typically it's the blue screen of death popping up saying something something, and then I restart, sign back on, and an error message pops up saying a file with a name that's a bajillion miles long is missing.

Does service pack 3 have, like, serious bugs or is it something else?

This didn't start until I installed it by the way...

EDIT: While I'm at it, is there any way to reverse some file deletions done by Spybot: Search and Destroy? x_x
