Odd network traffic
I use NetMeter to monitor in and outbound traffic to my computer, and starting a coupple of months ago, every once and a while, a series of a thousand or so 2.25 to 3Mb/s upload spikes start, amounting for almost 1Gb per day!!!!!

the spikes occur every 20 seconds, like clockwork.

i'll post a screenshot from netmeter next time it happens.

the odd thing is, no antivirus i've tried has found anything! same goes for antispyware!

whenever i start deleteing processes from the process list, it stops, then comes back after a coupple of minutes! also, if i am running on wifi, plug in my network cable, wait for it to connect, and disable wifi, the pulses subside for a bit, then come back!

i'm concerned because of the incredible ammount of data involved, and, it seems to have been increasing iver the past month.

Luckily, all the important data on my machine is encrypted, but, if the spikes are a data transfer, encryption won't mean $#!7.

any ideas?
screenshot comming soon.

Welcome to TSG.
What other programs are running at startup?
Maybe an Antivirus checking in for updates?
Do you have anything set on a schedule?

i have a few things starting at startup:

McAffe Security Center (free w/Comcast)
Dell QuickSet (control over hardware: LCD brighness etc...)
Network Sthuff (lan, wifi)
NetMeter (network traffic meter)
ATI control pannel
touchpad utilities
realplayer monitor
ctfmon
Spybot S&D
MSN Messenger
Windows Search
bunches of WinLogon BS you can't get rid of if you want windows XP to work

i've tried disabling each thing individually (using Spybot S&D), and nothing has seemed to stop the pulses

i've also noticed that if a program tries to use alot of a particular system resource, the spikes quiet down, but don't go away.

the antivirus wouldn't update every 20 seconds 24/7/365...

nothing runs on a schedule of anything less than 24 hrs...

-thanks,

My cable connection does pretty much the same thing,but I have never used anything to try monitoring it. It just sends and recieves to the cable provider to keep my connection open and retain my IP Address.

Try using WinPatrol to do your startup control. You don't need to remove the MS stuff from your machine, just disable it from autostarting.
I have only my firewall,network connection, and 3 antispyware starting at startup. Everything else are started as needed.

Can't you tell what process is producing the upload? Usually there is a monitor of some sort in the firewall that would tell you. It has to be an "allowed" application, after all.

Take a look at Current Ports to easily see all your connections, closed, open, waiting, and established.
