Binary Analysis

I recently came across a suspicious binary (.SCR) file in a
compromised system. As I started to analyse it by running a
'strings' against it I noticed there was very little readable text
in it, but the first line caught my attention: PECompact2.

I did some research and it seems this indicates the binary is
somehow compressed/obfuscated by using some sort of PE compression
tool (probably

Now I would like to unpack the executable to carry on with the
analysis. From what I could understand this would only be possible
by running it in a test win32 system, probably using a dissasembly
tool, since it only "unpacks" itself when being executed. Is that
correct? Would there be some other way of doing so, perhaps using
some sort of decompression tool? I was not able to find any so far.

Thanks for any help.
