I would recommend you doing the following things.

Windows XP if you have installed Service Pack 2 which I presume you have installed has a firewall in it, all you need to do is go into Control Panel then Security then click on the Firewall Settings and Enable it if it isn't. If a pop-up is telling you to get a firewall ignore it because it can lead to more Spyware.

I would recommend the following two programs they are both free:

For Spyware Removal Get Ad-Aware 2007 it is found at

For Viruses Get AVG by Grifsoft:

there is a firewall in windows you can use but you need antispyware or virus protection to quarintine your virus. http://www.oldapps.com will get you a copy of AVG antivirus programs for free. I like Zone alarm firewall also on same site. Try not to use pc until you get rid of virus othewise its a reformat hard drive.
These are the things I do and they work. You can print and try.
