Cleaning a Compromised System

Yes, it's a compromised system. Back-up any personal data (none of which
should be considered 100% trustworthy at this point) then format the HDD &
do a clean install of Windows. Please note that a Repair Install (AKA
in-place upgrade) will NOT fix this!

HOW TO do a clean install of WinXP: See
http://michaelstevenstech.com/cleanxpinstall.html#steps and/or Method 1 in
http://support.microsoft.com/kb/978307

After the clean install, you will have the equivalent of a "new computer" so
take care of everything on the following page before otherwise connecting
the machine to the internet or a local network (i.e., other computers) and
before connecting a flash drive, SDCard, or any other external drive to the
computer:

Tip: After getting the computer fully-patched, download/install KB971029
manually before connecting any external drive to the computer:

NB: Any Norton or McAfee free-trial that came preinstalled on the computer
when you bought it will be reinstalled (but invalid) when Windows is
reinstalled. You MUST uninstall the free-trial AND download/run the
appropriate removal tool BEFORE installing any updates, Windows Service
Packs or IE upgrades AND BEFORE installing your new anti-virus application
(which will require WinXP SP3 to be installed).

If these procedures look too complex - and there is no shame in admitting
this isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA or Geek Squad) computer repair shop.

To do a repair install, you need a CD that is at the same SP level than
the installed OS, you have SP3 installed? you need to slipstream SP3 to
your Windows installation CD, assuming it is not a factory restore CD.

Going back to SP2 is not a good idea because M$ is only supporting SP3
now as far as XP is concerned so you won't get security updates.

Since this machine is second hand, you don't really know what has been to
it so the best thing to do is to create a new installation CD with SP3,
and do a clean installation of Windows.

You really do not want to go back to SP2 - support by Microsoft for SP2 has
already ended. You will be leaving yourself wide open for trouble.

A clean install would be good since I did get it used.
Thanks to everyone who posted,
