Hi all, just needed to get some info concerning a problem i have...

I installed a firewall recently on my home PC.... it uses a dial-up ....

Basically about two days ago i started getting Net Bios (port 137) requests coming in at a rate of about 10 per hour. It usually starts about five mins after i log on to my dialup, and i am receiving requests from taiwan, US, mexico, and even malaysia too mention but a few.

I already researched the port 137 probe and already know what thats all about, however my question is basically, how the hell are they finding me? IMHO it doesnt seem to have be a conscious effort of these individuals to be scanning me and considering the fact that i use a very small local ISP I just wonder how these people or this program (dare i say : virus?) is detecting and querying my IP so soon after i log in. Is it just lucky guessing or is there something I am missing.

Thanks very much for any help..
