First there is no Spyware on OSX. No actual Virus's either. Shared shows network shares. How are you getting your internet? Router? WiFi? Neighbors WiFi? If you are using your own WiFi are you using an encryption key like WEP, WPA, WPA2 on the router or WiFi Access point? That is a computer connected to your network. Is yours the only computer on your network?

im using a router in my house...and i believe its a WEP...there are multiple computers in my house on the same network...is it just some one else in my family on the network/..thanks for the fast response

It could be a computer in your house. Does that name look familiar at all? Check all the computers hooked to your router and see if any network name looks like that share. If not, WEP is easily hacked. That is why we always recommend here at Mac Forums for people to use WPA or WPA2. MUCH stronger encryption that is very hard to ever hack.

well there is one other mac in the house and considering that there are 5 other house in my cirlce and nothing else around us and they all have theirs locked maybe its someone in my house...but just cause someone has access to my wireless doesnt mean they have access to all my information does it?

No, it's just a computer on your network. They can't log in unless you give them access.
