Does Windows Phone 8 have a virus?

[Valiant Lumia 720]

Do Windows Phone 8 get affected by any kind of virus?
What will happen if I insert an infected microSD to it or if I connect it to an infected PC?
Thanks.

In theory they could but i don't think there are any out yet. If you put a SD card in a PC with a virus then in your phone it won't be a problem because the virus' won't work on both platforms. I wouldn't worry about virus on WP.
