Yep, sounds like the Obliterator virus as described in Robey 'PrecinctOmega' Jenkins' article for Fanatic Online. It sounds like your character is at about stage 4...

here and you'll find a link to a copy of the article (and if you have any more questions about the article, the author can be found on the Conclave too).
I too have got a character in the early stages of infection by the virus -
Harry Cronenberg.
