The screensaver options etc don't appear, I had spywayre, but got rid of it, but it must be still around. I have Spyware Doctor as well as Search and Destroy. I ran a couple of things to change the reg, but no joy. I know feck all about registerys etc so any help would be appreciated.

You can go here http://www.kellys-korner-xp.com/xp_tweaks.htm and scroll down to line 128, second column Restore Desktop and Screensaver Tabs.
Download the fix, run it and it should be fine then.
