Definition: in the wild
Something still in use or available to the public. For example, "audio formats in the wild" means all the audio file formats that are still in current use. When a tweet, video or other post has been published, it may also be said it is in the wild.
Viruses in the Wild
The phrase often refers to viruses that have not been contained. Although tens of thousands of viruses have been unleashed, most of them have been eradicated and exist only in computer labs for research purposes. However, at any given time, there may be a couple hundred viruses that are still "in the wild," contaminating computer systems of unsuspecting users.
