Viruses - yes, a clever one could steal private-key passphrases, But if you're virus-protected and firewalled, it would find it hard to tell anyone about it. In any case, this is not a fatal objection because (if it was that easy) it would already be being done on a huge scale with credit-card details. And, sure, it does happen, but it's not common - and with far greater incentive than stealing keys would have.
Mailing lists - not a problem, because the posters sign their emails, not the list. The list isn't the originator of the post and so doesn't sign it.
