I wish to digress, as this is supposedly a serious topic. There is no word "viri", and if you attempt to use that as the plural of "virus" you open yourself to well-deserved ridicule.

Also, you may decide to use "fora" as the plural of "forum" when referring to platforms such as this one. Technically, you are not wrong so to do, but you cast yourself as a clown if you do. We see a lot of that here.

Now back to the subject...
