Howdy,

I run XP SP3 on my laptop...

About an hour ago, I found browsing (wireless) to be
unusually slow.

Next, I closed IE, and then was surprised to see that the
Wireless Network Connection icon on the tray remained "lit."

There was continuous traffic, but I could not figure out
what it was.

Next, I ran Ad-Aware, and SpyBot, and each found a few
seemingly trivial problems. I deleted those, rebooted, and
still have the network activity I have described.

In addition, I will mention that I run Kaspersky AV, and it
has found nothing.

Finally, I looked at my running processes, but don't spot
anything I know to be weird.

Thanks for suggesting next steps.

All the best,
