Hmm! I haven't used it, but I'd be pretty confident it works (this worm is pretty easy to clear off).

FixBlast is a little hyper-focused on the one worm and its variants. Most people don't know what they have, per se... so the best freebie is McAfee's Stinger. It's not as hyper-fast to add in variants as a one-off like the Symantec FixBlast, but I'd recommend it for most users who may not be sure what they've got on there.
