Help! Vundo Virus won't go away!

I have XP, service pack 2. I have used Uniblue, Spyware doctor, AVG (which now will not work) spyhunter, CCleaner, and numerous others to destroy the variants with no luck. I cannot use Google, or get into facebook etc.
My msn messenger and IE was not working but Avast corrected that. how do i get rid of the rest please?

 

Sorry, I didnt see before that your not supposed to put you HJT log on here... I'm new at this. My computer also cannot go into safe mode and gives me a svchoste.exe error when I boot up. I will have to come back later and go through the steps on what I can post on here. I've been battling this virus every waking moment when I'm not at work for weeks now and I'm bug eyed right now
