I'm having this weird issue with SpybotSD.exe where I try to open it and nothing happens. I'm running Windows Vista 64-bit SP2. When I try to open it, I get the Windows UAC prompt and then once I click to allow it, it never opens. However, it shows up under Task Manager. There is SpybotSD.exe*32 in the processes tab and I cannot shut it off. If I try to end the process, nothing happens. If I try opening Spybot again, it just shows up as a second process in the Task Manager and the actual program never opens. But for some reason I can end that second process but the original one will never go away.

I can't figure out what it could possibly be. It's driving me crazy! Please help!!
