Does the Mac version of BitDefender detect Windows malware? I need to know if BitDefender scans incoming emails and external drives?

I emailed BitDefender's support after installing the trial but never received a reply.

I currently use Kaspersky Internet Security but would consider switching when my Kaspersky subscription runs, as long as BitDefender can at least scans incoming emails.
The BitDefender website does claim that the Mac version will remove Windows malware. I can't find anything specifically mentioning email or network drives, but it would be a significant and unlikely oversight.

It's worth pointing out that BitDefender contains (and has contained) security vulnerabilities that can be exploited in itself.
