Worms will often give themselves randomized names to avoid user detection, you won't find many worms that will names themselves "IAMAVIRUS.worm". It's impossible for us to tell what the worms would do without seeing their inner workings, but to be honest you should probably just remove them from your machine if Windows Defender flags them.
