Were you able to unpack it or not ?
To unpack PeCompact2, there are some nice scripts for OllyDBG.
Openrce.org has links for them, if I'm not mistaken.

After you unpack the binary, you can disassemble it with IDA, W32Dasm or
some other disassembler.
Or, you can use OllyDBG to analyse and debug it, but remember, you are
running the exe, so the machine will get infected (it's a test machine
correct?).

Regards,
Pedro
