Windows Live OneCare

I’m curious if anyone has tried Windows Live OneCare (via Amazon note: affiliate link used) with Firefox, and especially with Thunderbird. I personally haven’t tried it. A quick Google search doesn’t turn up to much info. Is it detecting viruses in emails correctly and problem free? Or is it causing chaos? I’d love to hear from someone who has used it.

As a reminder, just because you don’t use Outlook doesn’t mean your immune from viruses. You still need a virus scanner.
