A couple of things, Think_a_lot. Firstly, is it advisable to always keep your anti virus software updated, which, correct me if I'm wrong, it doesn't sound like you have done until just now.
You can download a removal tool for the Blaster worm from the link below:

Teekids is a variant of the Blaster worm, so the tool should remove that for you as well.
Good luck!
