'HOT XXX' dialer help please!!!

i, im having real problems with this HOT XXX spyware. I'm not too knowlagable in computers so i would be extremely grateful if you would help me.
HOT XXX puts a recurring shortcut on my desktop and start menu, changes my homepage, and after about 15 minutes of internet time pops up with a pornographic dialer and disconnects me.

I have run 'hijack this', and this is my current log file
