Surprised no one has said this yet but...
Those anti-static bags are designed to transfer the static electricity from the item in the bag, so a static charge doesn't build up on the item in the bag. This is atleast as far as I know. Otherwise you'd get static buildup on the item in the bag.
But I haven't personally tested the conductivity of the bag, but if its designed to work the way I always thought they did, your attempt to keep your computer protected might have just backfired on you...unfortunately.
But I wouldnt know without testing it.
