spybot will not open

[00dev]

my computer has been infected with what i believe to be vituomode (or whatever it's called)
I'm getting pop ups slow internet and spontanous shutdowns
I tried running spybot in safe mode and still nothing i would double click on the icon and nothing happens except a brief hourglass icon.
hijackthis will not work
nor will combofix or sdfix
so I can't post a log right now

also when I shut down my computer i will get the end a non-response prompt
for spybot.
i
have windows XP

any ideas?
