So how is this useful in any way? Surely whoever sent a virus mail to my iOS device can easily send it to someone else? Probably sends it to millions others? And why would I forward this virus mail instead of deleting it immediately?
Because that might be a freaking infected Microsoft Office file that is supposed to deliver to someone else !
You guys have no idea how people here are addicted to Microsoft Office. People just can't do anything, I mean, ANYTHING, without Microsoft Office. Every kind of document you may imagine is .doc or .ppt. They did even put codes, yes, bloody, XML, CODES, in those freaking WORD files!
It's also extremely common to co-work on a same Office file through email too. For countless time we have to wait for documents to be amended and forward to final submission right after we received the email. And unfortunately, most mail servers here has no anti-virus installed. Yes I know there is something called file server from last century. Go telling my boss about that.
The truth is: we're surrounded by idiots. And that's why we need anti-virus to protect THEM, but not ourselves.
