Sobig.F was packed with tElock. It's a PE file protector. It "encrypts" the 
program's code and data, and tries to detect debuggers before giving control 
to the real program. If you don't have the right tools and skills it could 
be difficult to unpack it. IIRC, it took the anti-virus companies two days 
to successfully unpack the program. All they really needed to do was dump it 
from memory while it was running and they could've analyzed it immediately 
with any disassembler.
