    This alone can hardly be conclusive that you've been rootkitted, unless you've understated the mouse surfing on its own accord of course. :o

    So far sounds like a memory leak; runaway process somewhere in XP sucking overhead. Mouse erraticism could very well be related.

    Is this on your home LAN where you have a router that you could independently monitor whether your machine is making or requesting connections out to the net without your knowledge? What you might want to consider as a medium, longer term strategy is setting up an independent IDS like snort to monitor all traffic in and out of your gateway, and ideally on a one way RX only line so you can be absolutely sure of its integrity.

    I'll once again state the obvious that if you've been owned, there's nothing you can possibly do to know 100% that you're not anymore but to do a complete reinstall. Especially, when your attempts originate from the owned machine in question.

    > Any more suggestions ?

    Ditto from above. Peace of mind = complete reinstall, In the future use a 3rd party IDS like snort.

    Still, from what you've desribed, it might still be nothing more than a memory leak.
