Why wasn't SP2 installed 4 years ago?
You can't possibly have a functional anti-virus application installed if SP2
isn't installed so see...

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.
