My firewall logs show connection attempts named nbname(137) and nbdgram(138) almost every minute from the local LAN network.
As I researched some information about them, I have realized that they are not look good.
The nbname is meant to stop someone from joining the network, isn't it? And the nbdgram is to broadcast datagrams, according to this page. http://www.mycplus.com/out.asp?CID=1&SCID=186
I have two PCs and one file server in the same network. The file server is the one sending the nbname packets to everywhere. And the both pcs seems to be infected with the nbdgram since both pcs' firewall logs indicate each of their connection blocks with the name of nbdgram(138).
My question is, how can I remove them? I tried to search entire harddisks by the keywords of nbname and nbdfram, but with no luck I wasn't able to detect any files.
I need you experts help. Thanks in advance.
