It's a Blessing in Disguise. Delete It. You are Flirting with some Dangerous Stuff.
Programs, Games and I'm sure other Apps. and Images are something you want to stay away from on the Gnutella Network.
A very Large percentage, (like 99%) are either Viruses, Worms, Spam or just Corrupt.
About the only things to download are Audio, Video, and E-Books and then your still not safe. Scan EVERYTHING with a Good AV Before Opening.
There is a Ton of Info on these Forums about this Stuff. Take some time to read and learn about what you may get yourself into While using LW.
I would Run a Full System Scan with your AV, ASAP since you did try to Open that Program. Hope this Helps
