Help!

Adaware tells me I have the Win32.P2P-Worm.Alcan.a worm.

It persistantly reimplants itself on start-up after I remove it with adaware.
It has something to do with Limewire because limewire constantly turns itself on despite the settings in the program (off on startup, uninstall + reinstall), my computer cant:
-can't run regedit
-can't access task manager
-can't use ctl+alt+delete, it doesnt open

When I uninstall Limewire, the program still turns on a persistent window looking for a lost file.

I have seen many people in recent years on the net who have had the same problem with the Win32.P2P-Worm.Alcan.a worm.

Can someone help me through removing this thing before I start my thesis on my pc in January?
-cant get to registry
-cant access task manager
-cant use ctl+alt+delete
-persistent startup of limewire
-
Where should I start?
