if it has that many viruses on it then maybe a system restore wont fix the problem but its worth a try
if you need a full re-installtion of Xp let me know and if you want a trip to udon i will show you how
it all depends how many extra programs you have installed on your PC to how difficult it will be
i can back up all your files on my portable hard drive
it should only take about an hour and half
