Hi colfos, welcome to DaniWeb :D
You need to go to Windows Update and get SP1a for both XP and IE
Get the PocketKillbox from here:
http://bleepingcomputer.com/files/spyware/KillBox.zip
Unzip the file to your desktop.
Go offline until this is completed (you may wish to print these instructions).
Boot into Safe Mode and do a search for these files and delete any instances found:
param32.dll
guninst.exe
popup_bl.dll
systr.dll
svrhost.exe
If any could not be deleted, (most likely param32.dll), run the PocketKillbox and paste the full file path of file in the box and click on Delete on Reboot. Click on the button with the red circle and an X in the middle; you will get a message saying File will be deleted on next reboot, Process and Reboot now?, Click Yes to reboot. (Note: the 'file path' will be something like C:\WINDOWS\System32\param32.dll)
Reboot normally and delete any unwanted icons from your desktop.
Empty your Recycle Bin.
Scan with hijackthis, and have it fix the following entries:
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://www.jimbutt.com/stuffs/ (unless you set this yourself)
R0 - HKLM\Software\Microsoft\Internet Explorer\Main,Local Page = C:\WINDOWS\SYSTEM\blank.htm
