By default your shared files / downloads will normally be located here: C:\Documents and Settings\"your account name"\Shared
So if they are there, you are safe. That is a long way from your Programs folder.

As for purchasing from LimWire.org, no you obviously didn't but found a site using a search like google which said LW, but wasn't. That is what scam sites do. eg: http://www.gnutellaforums.com/open-d...s-success.html

You can find a list of scam sites here: Known Scam Sites (click on link)

I'd be curious to know where you purchased your original 360 ProShare because it definitely was not LW.org site. And the price is different.

You should be safe using LW Basic.
