Back-up any personal data [1] (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://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 using a flash drive or SDCard that isn't brand-new or hasn't been
freshly formatted:

Tip: After getting the computer fully-patched, download/install KB971029
manually:

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.
