Unhappy unwanted network traffic on tcp port 135


I have a DSL connection to my home PC through which I surf the internet. I need to pay for every byte tranmitted or recieved by my PC.
I am finding that requests are comming on a number of IP addresses on TCP port 135 and my computer replies with ICMP, thus making me pay for them. Can you tell me if there is way out to stop this unwanted traffic?
here is the output from Ehtereal.

Yeah - you can turn off icmp echo requests and block port 135 using iptables.

"I need to pay for every byte recieved by my PC."
It's a joke?

I should do a company like this and ping all my customers.

Yah, cos in India, nobody seems to care for these subtle things, they just go for easy implementation. Like for example, if I'm using a different browser than IE, I won't be able to view my internet usage by logging into my provider's site. It clearly says "Sorry, IE is required". I guess they don't have contract with Microsoft.

Please tell me how I turn off ICMP and request on port 135?
I'm just a newbie in those administration things.
