Missing desktop & Start menu

[ajs1951]

I have a pop-up for "Total PC
Defender" on my desktop and I can't remove it. I have no start menu so I can't download  anything and can't access taskbar manager. When I restart computer I get everything returned to normal for about 20 seconds and then it all disappears and the pop=up returns. I have tried inserting my Windows XP utility and driver disc but nothing happens. Any ideas?
