go to ther comntrol panel and then select add/remove programs there you will find the list of programs installed, find the xpsp2 update and then remove, the pc is likely to need a reboot to complete the application removal but make sure you have a firewall before you remove sp2
check that you dont have spyware/adware, i have a program called Webroot Spyware sweeper it cost me £30 ans has a yrs update included, i was shocked to find how much unwaed eyes were found
a free program called Spybot search and destroy can also be used but not as powerful
