Bearshare Auto-Install?

    Here's a rundown of the network we share with the neighbor...

    Cable --> Modem --> Neighbor's Router

    Neighbor's Router goes to Neighbor's Computer and My Router

    My Router connects to my 3 computers (A, B, C)

    Everything was fine and dandy up until a week ago when one of my computers tried to change Neighbor's Router to run on subnet 0.0.0.0.

    Neighbor's Router then kicked computers B & C out of the network, while leaving Neighbor's Computer and Computer on. Only side effect was slight slowdown on the internet.

    This happened for a few days off and on, after my neighbor reset things.

    Then, a few days ago, one of the computers automatically installed BearShare on Neighbor's Computer! Only Computers B & C had been running BearShare. I have since uninstalled Bearshare from B & C, but have not reconnected them to the network (neighbor doesn't trust them yet), but have not checked for anything BearShare related in their registries....

    Any idea on what may have caused this?

    It is not possible for your computer to change your Neighbor's router's subnet. Perhaps you meant your PCs subnet's change. Someone would have to manually reprovision your neighbors router to make it change which subnets it is allowing IP addresses to be assigned.. In addition your PC gets all of it's assignments thru your router via DHCP and your router get's it assignment via DHCP (or static address is programmed) from your Neighbor's router. If A, B, & C were on the same subnet they should all have dropped not just B & C. Unless they are using wireless then their could be other factors at your end of the network. At any rate this is not an topic for the Malware Forum.

    I assume this question is about Bearshare. It is considered malware and should not be used. In addition P2P programs in general are not safe, especially in this ( I would assume illegal) configuration. Do you and your neighbor have file sharing turned on? Are the shares password protected and do only you know your passwords and only your neighbor knows his?

    The question was mainly about BearShare auto-installing itself on my neighbor's computer. I have since uninstalled it from my computers, and deleted all executables/archives pertaining to it.

    Not surewhat you are refering to when you say 'I would assume illegal configuration'.

    We have file sharing turned on so that my 3 computers can access each other, and we have been able to access his computer. They are not password protected. If this were done, would user on computer A need to enter a password in order to listen to music stored on computer C?

    Two different people sharing a cable connection! What do you mean by neighbor? Same house? Or is this an apartment? Ask the cable company if it is legal! You explanation just did not sound legal to me but I'm not the cable police. ;)

    It is a very bad idea to not password protect the shared drives. Yes it means you would need to enter a password and that is what you want to have for proper security.

    It's a duplex, and we *have* talked to the cable company.....

    As for passwords, would they be entered when starting a program (iTunes), or when loading *each* file?

    Then you should be OK!

    It would normally be requested as you connect to the drive. So as long as you stay connected with the program, it would only ask as first connected. Another method to use is to Map a network drive which mounts the drive just like a local disk when your PC starts up. Obviously if the other PCs are not on they will not be found at the time you startup and you will get an error message but you can just OK past them and tell them to look again next time.
