Subject: Q about virus and cleanup (attn Chris) (semi-OT)

Sorry if this has already been discussed...

I have a couple questions regarding the virus embedded in Fafis 2.0:

(1) Is it likely that my system is fine considering my antivirus software caught
the suspicious newly-created file before it was run? I can't find any other
traces (e.g., modified hosts file, modified registry keys, etc.)

(2) I'm not familiar at all with exe compression/encryption. But isn't it
possible that the worm attached itself to the clean fafis exe first (and without
the author's knowledge)--*before* the author compressed? The author could have
tested the uncompressed exe for a while before finally packaging it up for
distribution. (Note : It still would apparently be the first reported case of
this worm attaching itself to files, but that's not what I'm asking about.)

Thanks,
Michael
