The AV plugins don't need converting since they use system() so we can't do anything about that blocking. Though you may need to make sure you get rid of a lot of stuff BEFORE you run AV just to mitigate any hanging that may occur because of this.
Yeah, the standalone AV plugins call system(), but the ones that directly communicate with AV daemons (I'm thinking clamdscan) has to be rewritten (if I'm not misunderstanding).
