how do i close my icmp port?

i want to close every port on my system, so that i don't get someone testing each of my ports every couple of hours and doubling my ping. playing counterstrike:s is great and all but when my ping jumps from 60 to 400 for 3 minutes coz someone's testing all my ports, its bloody annoying. i dont have any spyware, i've checked a thousand times, and i have all the proper defences, but i don't want ppl checking my ports! it's annoying. running pentium 2.8 1g ram or so with win xp sp2 all the updates, avg running 24/7 updated etc spywareblaster in position all that

Could there be another reason i am getting 400 ping every couple of hours? it isn't me downloading something (or anyone else on my network)

could my other computer have spyware.. hm i haven't checked that yet, i'll go check it now.

 

Huh? If you want to close all your ports yank the plug to your modem... Im not sure what your saying? It might be bad/faulty cabling/telephoneline wiring; Or it might be crappy servers or something in ur pc causing studder.

 

nah when im playing for like 1 hour 50 minutes, it's perfect ,30 ping, and all

every hour or so i get a 5 minute batch of 400 ping

nothing to do with ANYTHING Else, and it seems like it could be someone port scanning me.

is this possible? maybe i should ask in somewhere where people know how to deal with malicious people.

 

I think your being overly paranoid. Too much CS for ya'

 

hmph. overly paranoid? im playing just fine then blam ping jumps to 500 and i've jumped from 90 frames per second to 5.. i turn in a circle and it's like someones taking pictures and showing them to me. maybe it's too much cs was wondering if there is a way to stop it.
