Have a feeling this will attract a bit of people due to the high generalism of my title...

First of all, Ide like to say hi to everyone, as I am new to this community. Infact, this is my first post. However, I am not new to Limewire. I have been using since, well, probably the first time I heard about it.

What brings me here is this-

I have a question that I think I will find a true answer to by posting in this community.
I have only used limewire for majorly music, and a few odd and end searches, just a program or two. But, I have never downloaded any videos of any sort. Well, maybe one or two, but thats it.

Recently I have refound interest in a certain show I watched way back when.
I did a search on it on LW, and it turned up results for ALL the episodes of the series, which was glorious and just what I expected. But, it also did another thing I highly expected- "waiting on busy hosts" and "needs more sources" was yet again a common hinderance for most the downloads.
Well, I thought to myself "why not search 'i general' for this set of episodes instead of what I previously did- search only for video type files", because perhaps someone had compressed all the episodes (there were less than 30 altogether) into a zip/rar file. If so, then downloading it would be much faster than waiting for sources or non busy hosts.

I did just that, and it turned up several results. I queued several of them, jsut to be sure I got all I wanted.
When some of them were done downloading, I unzipped them, only to find this common amongst the downloaded zip files- a setup.exe file with the name of what was downloaded.

My question is, should I run the setup or not? Are show seasons that have episodes commonly downloaded as a setup.exe, or is this a sure sign of a virus?

Is there a way to find out the contents of the setup.exe file without actually running the .exe? Just to make sure its what I want...
