If these information virii are using you as a host are you culpable for actions they inspire? (which boils down to, "is there free will?" an age-old and classic debate, to which many people have decided the answer is "no")
There is free will. Not choosing to believe in it doesn't change the fact that it exists...it's just a cop out for irresponsible actions.
This reminds me of a discussion I heard recently where someone asked "is sin solely based on your genes?"
