Well that may explain it. .exe and .rar files are notorious for being infested with virii, worms and a lot of other FUN stuff. If it were me, I would DELETE it Now unless you enjoy fixing your computer. P2P is probably NOT the place to dn/ld program files.
You can try Bitzi. I have seen program files rated on Bitzi but the thing about that is everyone that gets a paticular file all use the same hacked key.
Use your own judgement here and Good Luck.
